I just started learning Meteor JS on a fresh copy of OSX. I used the Meteor install instructions to install it. Everything works well - I can install Meteor packages and run the local instance. But where is Node.js and npm? I assume it must be installed with Meteor because everything runs, but the npm and node command is not available. Am I supposed to install Node separately?
Thanks,
Kevin N.
Edit: Corrected npm in the question title which OS X keeps changing to nom.
As of METEOR#1.1.0.2, node and npm are stored in :
/home/username/.meteor/packages/meteor-tool/1.1.3/mt-os.linux.x86_64/dev_bundle/bin/
(The path depends on both the username and architecture of course).
If you're doing only Meteor dev, you won't need node on its own, you might however need npm to install Meteor related tools such as Meteor Up (mup), in which case you need to install npm separately or alias the command to use the Meteor one.

I am using react native and Expo. I am unable to build new app because after I use expo init appName it shows the following error.
Heres the full message:
📦 Using npm to install packages. You can pass --yarn to use Yarn instead.
√ Downloaded and extracted project files.
× Something when wrong installing JavaScript dependencies. Check your npm logs. Continuing to initialize the app.
✅ Your project is ready!
To run your project, navigate to the directory and run one of the following npm commands.
- cd Scanner
- npm start # you can open iOS, Android, or web from here, or run them directly with the commands below.
- npm run android
- npm run ios # requires an iOS device or macOS for access to an iOS simulator
- npm run web
I tried multiple times to create a blank project, also tried npm install to install failed/not downloaded libraries and continue after failure but it showed another error:
npm ERR! code Z_BUF_ERROR
npm ERR! errno -5
npm ERR! zlib: unexpected end of file
also tried npm cache verify that showed cache is ok Content verified: 3562 (252580364 bytes).
So, How can I solve this issue?
Problems related to npm installation are very common If you do any mistake in early installation, but is avoided. Learn more about npm tree.
Steps worked for me are :
npm cache clean --force
npm cache verify
npm -g uninstall expo-cli --save
npm install expo-cli --global
expo init app-name
cd app-name
npm start
Always run as administrator if working on Windows and in root directory.
The solutions above didn't work for me but if you use 'npm install' in the directory of the app you get a clue that you shuold try 'npm install --force'
err message
You should have all these files folders and files at the start of the project otherwise not all the dependencies have been installed which is why we were getting the problem.folder structure
After you have added --force to npm install you have all the dependencies installed. Now you can run the app with npm start.
Unfortunately, all the solutions described above didn't work on my machine...
Here is my latest solution for this problem...
This worked 100% on my machine...
Use npm i -g expo-cli
This will automatically add the required packages and also remove the unnecessary ones.
Yes, surely, you don't need to uninstall and re-install it again.
Just follow my steps.
And, you can create your expo project using expo init.
I hope my solution will help you out from this annoying problem....
I just did npm install and it worked for me, but I had do that every time I create a new expo project.
I also encountered this problem, and finally found that it was the problem of react native cli，I installed the latest version of react native cli，Expo is back to normal
This Error is regarding to the git account. expos need a git account to setup react native project
If you are using windows you need to install git in your local PC
after that open your Terminal and type this command
git config --global user.name "your_username"
git config --global user.email "your_email_address#example.com"
after that clone any github project to your local computer. it will ask to login to Github
after all these steps try expo init <projectname>
The simple way to settle that error is by using "expo-cli init app-name" instead of "expo init app-name".
I tried and worked perfectly for me. Hope it will help you guys.
i have faced a similar problem and running yarn set version 1.22.1 fix it
Run the Command Prompt as an administrator. And run the following command:
npx create-expo-app AwesomeProject
Because I use the Netlify CLI tools on travis, I need to have a node version above 8 but the R container I use only has 6.12 according to the error message. I saw that it is possible to specify the node version for java script projects and there is an answer for PHP projects here on StackOverflow, but I tried both and they did not work for my case. What is the proper way of installing a specific node version in an arbitrary travis container such that other applications can access it ? Or maybe even better, (how) can I make npm satisfy the minimal version dependency on node when installing the Netlify CLI tools? I have no prior experience with npm. You can find the version history of my .travis file here.
To install Netlify CLI, make sure you have Node.js version 8 or higher
Based on the docs for Netlify here
Quickest solution for Travis
Optionally, your repository can contain a .nvmrc file in the repository root to specify which single version of Node.js to run your tests against.
The quote from the docs say to add a .nvmrc file to your project at the root with the version
.nvmrc
8.14.0
Note: replace the version with the one compatible with your project that meets all requirements. Also, the .nvmrc file is only read when node_js key in your .travis.yml files does not specify a nodejs version.
Based on the solution provided by #talves, I figured out I can modify the before_script step to install a specific version of node, e.g. 8.14:
before_script:
- nvm install 8.14
- npm install -g netlify-cli
- Rscript -e 'blogdown::install_hugo()'
As nvm and npm were already installed. To install the latest stable release replace 8.14 with node above. That way, I don't need the .nvmrc file.
I am trying to deploy an app that has been upgraded to meteor 1.7 using the setup for passenger outlined at puhsionpasserger.com, however when I try and access the app I get an error in the console of
Error: The core-js npm package could not be found in your node_modules directory. Please run the following command to install it: meteor npm install --save core-js
Being shown on the web page (although the favercon is correct so its trying).
The app runs fine locally (as in on the dev machine).
Give its deployed, meteor doesn't exist on the machine.
I tried npm install --save core.js and it reported one package installed, but still no joy on the app front.
I'm not sure where to go from here. Any thoughts?
Edit:
I just tried building the app without the --server-only flag with no change. Deployed the app the way I do with the v1.3 instances of the app and no change.
One thing that I did get when running npm intall from the /programs/server directory was
Binary is fine; exiting
npm WARN lifecycle meteor-dev-bundle#~install: cannot run in wd %s %s (wd=%s) meteor-dev-bundle# node npm-rebuild.js /opt/bundle/programs/server
added 131 packages in 13.857s
I'm not sure if the warning means anything in particular.
I know how to package and then deploy meteor application. But recently for one project i'm stuck at an error which i couldn't resolve.
Steps I followed for package and deploy of my meteor app:
1. meteor build package
2. cd package
3. tar -xf inventoryTool.tar.gz
4. cd bundle/programs/server
5. npm install
6. cd ../..
7. PORT=<port> MONGO_URL=mongodb://127.0.0.1:27017/dbName ROOT_URL=http://<ip> node main.js
Here is the log for the error when i run the npm install(STEP 5) command.
Is there anything missing in my execution?. I'm not using the fibers package anywhere in my project. Does anyone have solution to this problem? Thanks in advance.
Why this happens (a lot)?
Your local version of node is v8.9.4. When using the build command, you will export your application and build the code against this exact node version. Your server environment will require this exact version, too.
An excerpt from the custom deployment section of the guide:
Depending on the version of Meteor you are using, you should install
the proper version of node using the appropriate installation process
for your platform. To find out which version of node you should use,
run meteor node -v in the development environment, or check the
.node_version.txt file within the bundle generated by meteor build.
Even if you don't use fibers explicitly it will be required to run your Meteor app on the server correctly.
So what to do?
In order to solve this, you need to
a) ensure that your local version of node exactly matches the version on the server
b) ensure that you build against the server's architecture (see build command)
To install a) the very specific node version on your server you have two options:
Option I. Use n, as described here. However this works only if your server environment uses node and not nodejs (which depends on how you installed nodejs on the server).
II. To install a specific nodejs version from the repositories, you may do the following:
$ cd /tmp
$ wget https://deb.nodesource.com/node_8.x/pool/main/n/nodejs/nodejs_8.9.4-1nodesource1_amd64.deb
$ apt install nodejs_8.9.4-1nodesource1_amd64.deb
If you are not sure, which of both are installed on your server, check node -v and nodejs -v. One of both will return a version. If your npm install still fails, check the error output and if it involves either node or nodejs and install the desired distribution using the options above.
To build b) against the architecture on your server, you should use the --architecture flag in your build command.
After upgrading Meteor to 1.3.x version NPM really came to play. But as always there is back side of the coin: build size.
On meteor 1.2.x build size is ~50MB, ~7k files
On meteor 1.3.x build size is ~190MB, ~27k files.
Twenty seven thousand files. That's quite a number. Not to mention path size exceeding 256 (a trouble for windows users).
I've dig into what meteor included into the build and it seems that all the npm_modules is here with all the stuff that is need to build some modules and their dependencies.
The question is: how to build meteor app without unnessesary npm files, leaving only the ones that are actually used by app at runtime?
Update:
On meteor 1.4.1_3 if you create a simple project meteor create dummy-project and go through all the common stuff like npm meteor install and meteor npm prune --production and them make a bundle out of it with meteor build c:\dummy --directory you will get a folder with the same 7k files and almost 2k folders (by the way it will not run node main.js out of the box as you might expect). If you tinker through folders you can find babel compiler inside that takes ~3.5k files.
Why do I need babel compiler inside compiled app?
To gain an introspective of your packages,
npm list --depth 0
to see the current packages in your project with only one level.
Inspect that list, and decide if you don't need a package and uninstall it.
You can also use other flags such as
npm list --depth 1 #the number represents the max depth
npm list --long true #for more information about the packages
npm list --global true #to check your global packages.
npm help-search <searchTerm>
Hope that helps you gain more insight in your packages. help-search Link
You may see that multiple packages depends on the same packages, and then it's up to you to decided what your application needs to run successfully.
Edit 1
You can exclude the packages inside your devDependencies, so that when you're publishing/deploying your code you have a cleaner package.
You do this by using npm prune --production - that removes all your devDependencies, and will require your users to do a npm install for your package to work. For info here
