I am trying to get #next/mdx running with the new app directory. I followed the setup in the Readme of the package but i get the following error message when I try to render an mdx page. I can not find any information on this package what so ever.
Module not found: Can't resolve 'next-mdx-import-source-file'
1 | import { Fragment as _Fragment, jsx as _jsx, jsxs as _jsxs } from "react/jsx-runtime";
> 2 | import { useMDXComponents as _provideComponents } from "next-mdx-import-source-file";
3 | function _createMdxContent(props) {
4 | const _components = Object.assign({
5 | h1: "h1",
This error occurs if the file mdx-components.js is not present in the project root directory.
This dependency is not an actual package but rather some next magic which actually imports the mdx-components.js file. In my case I missed out on on the plural.

I want to use https://github.com/bazelbuild/rules_webtesting. I am using Bazel 5.2.0.
The whole project can be found here.
My WORKSPACE.bazel file looks like this:
load("#bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
http_archive(
name = "io_bazel_rules_webtesting",
sha256 = "3ef3bb22852546693c94e9b0b02c2570e74abab6f800fd58e0cbe79492e49c1b",
urls = [
"https://github.com/bazelbuild/rules_webtesting/archive/581b1557e382f93419da6a03b91a45c2ac9a9ec8/rules_webtesting.tar.gz",
],
)
load("#io_bazel_rules_webtesting//web:repositories.bzl", "web_test_repositories")
web_test_repositories()
My BUILD.bazel file looks like this:
load("#io_bazel_rules_webtesting//web:py.bzl", "py_web_test_suite")
py_web_test_suite(
name = "browser_test",
srcs = ["browser_test.py"],
browsers = [
"#io_bazel_rules_webtesting//browsers:chromium-local",
],
local = True,
deps = ["#io_bazel_rules_webtesting//testing/web"],
)
browser_test.py looks like this:
import unittest
from testing.web import webtest
class BrowserTest(unittest.TestCase):
def setUp(self):
self.driver = webtest.new_webdriver_session()
def tearDown(self):
try:
self.driver.quit()
finally:
self.driver = None

When I try to do a bazel build //... I get (under Ubuntu 20.04 and macOS):
INFO: Invocation ID: 74c03efd-9caa-4174-9fda-42f7ff37e38b
ERROR: error loading package '': Every .bzl file must have a corresponding package, but '#io_bazel_rules_webtesting//web:repositories.bzl' does not have one. Please create a BUILD file in the same or any parent directory. Note that this BUILD file does not need to do anything except exist.
INFO: Elapsed time: 0.038s
INFO: 0 processes.
FAILED: Build did NOT complete successfully (0 packages loaded)
The error message does not make sense to me, since there is a BUILD file in
https://github.com/bazelbuild/rules_webtesting/blob/581b1557e382f93419da6a03b91a45c2ac9a9ec8/BUILD.bazel
and https://github.com/bazelbuild/rules_webtesting/blob/581b1557e382f93419da6a03b91a45c2ac9a9ec8/web/BUILD.bazel.
I also tried a different version of Bazel - but with the same result.
Any ideas on how to get this working?
You need to add a strip_prefix = "rules_webtesting-581b1557e382f93419da6a03b91a45c2ac9a9ec8" in your http_archive call.
For debugging, you can look in the folder where Bazel extracts it: bazel-out/../../../external/io_bazel_rules_webtesting. #io_bazel_rules_webtesting//web translates to bazel-out/../../../external/io_bazel_rules_webtesting/web, so if that folder doesn't exist things won't work.
My use-case is this:
I have a static library which I want to be available for some profiles (e.g. "gcc", "arm-gcc", "mips-gcc").
I also have an application which links to this library, but this applications should only build using a specific profile (e.g. "arm-gcc").
For this I am modifying the app-and-lib QBS example.
The lib.qbs file:
import qbs 1.0
Product {
qbs.profiles: ["gcc", "arm-gcc", "mips-gcc"] //I added only this line
type: "staticlibrary"
name: "mylib"
files: [
"lib.cpp",
"lib.h",
]
Depends { name: 'cpp' }
cpp.defines: ['CRUCIAL_DEFINE']
Export {
Depends { name: "cpp" }
cpp.includePaths: [product.sourceDirectory]
}
}
The app.qbs file:
import qbs 1.0
Product {
qbs.profiles: ["arm-gcc"] //I added only this line
type: "application"
consoleApplication: true
files : [ "main.cpp" ]
Depends { name: "cpp" }
Depends { name: "mylib" }
}
The app build fails. Qbs wrongly tries to link to the "gcc" version of the library instead of the "arm-gcc" version, as you can see in the log:
Build graph does not yet exist for configuration 'default'. Starting from scratch.

The following products could not be built for configuration default:
app
The build fails only when selecting one profile in the app.qbs file, and this profile should not be the first profile in the qbs.profiles line in the lib.qbs file.
When selecting two or more profiles - the build succeeds.
My analysis:
I think this problem is related to multiplexing:
The lib.qbs contains more than one profile. This turns on multiplexing when building the library, which, in turn, adds additional 'multiplexConfigurationId' to the build-directory name (moduleloader.cpp).
The app.lib contains only one profile, so multiplexing is not turned on and the build-directory name does not get the extra string.
The problem can be solved by changing the code (moduleloader.cpp) so that multiplexing is turned even if there is only one profile i.e. with the following patch:
--- moduleloader.cpp 2018-10-24 16:17:43.633527397 +0300
+++ moduleloader.cpp.new 2018-10-24 16:18:27.541370544 +0300
## -872,7 +872,7 ##
= callWithTemporaryBaseModule<const MultiplexInfo>(dummyContext,
extractMultiplexInfoFromProduct);
- if (multiplexInfo.table.size() > 1)
+ if (multiplexInfo.table.size() > 0)
productItem->setProperty(StringConstants::multiplexedProperty(), VariantValue::trueValue());
VariantValuePtr productNameValue = VariantValue::create(productName);
## -891,7 +891,7 ##
const QString multiplexConfigurationId = multiplexInfo.toIdString(row);
const VariantValuePtr multiplexConfigurationIdValue
= VariantValue::create(multiplexConfigurationId);
- if (multiplexInfo.table.size() > 1 || aggregator) {
+ if (multiplexInfo.table.size() > 0 || aggregator) {
multiplexConfigurationIdValues.push_back(multiplexConfigurationIdValue);
item->setProperty(StringConstants::multiplexConfigurationIdProperty(),
multiplexConfigurationIdValue);
This worked for my use case. I don't know if it make sense in a broader view.
Finally, the questions:
Does it all make sense?
Is this a normal behavior?
Is this use-case simply not supported?
Is there a better solution?
Thanks in advance.
Yes, the default behavior with multiplexing is that the a non-multiplexed product depends on all variants of the dependency. In general, there is no way for a user to change that behavior, but there should be.
However, luckily for you, profiles are special:
Depends { name: "mylib"; profiles: "arm-gcc" }
This should fix your problem.
Custom Function what I made did not work in presto on EMR.

I got the source from github (branch 0.188) on my Mac and built presto.
When we placed the above UDAF on its presto, it worked perfectly.
Perhaps there is a mistake in the installation procedure for presto on EMR.
Solved!!
The Custom plugin did not work because it was not a plugin creation, but a way of deploying on EMR was wrong.
Since I did not deploy to all nodes in the procedure I performed, I confirmed the operation by registering the following shell as a bootstrap action.
#/bin/bash
aws s3 cp s3://hogehoge/presto-udaf-1.0-SNAPSHOT.zip /tmp/
sudo mkdir -p /usr/lib/presto/plugin/
sudo unzip -d /usr/lib/presto/plugin/ /tmp/presto-udaf-1.0-SNAPSHOT.zip
10.1. SPI Overview — Presto 0.198 Documentation
Plugins must be installed on all nodes in the Presto cluster
(coordinator and workers).
Create Bootstrap Actions to Install Additional Software - Amazon EMR
You can use a bootstrap action to copy objects from Amazon S3 to each
node in a cluster before your applications are installed. The AWS CLI
is installed on each node of a cluster, so your bootstrap action can
call AWS CLI commands.
From what you wrote there are two things which are missing.
make sure that you used maven packaging presto-plugin in your pom.xml
also implement com.facebook.presto.spi.Plugin which in getFunctions method would return your function.
Take a look in presto-geospatial Presto module and see com.facebook.presto.plugin.geospatial.GeoPlugin and its pom.xml as reference.
I'm getting this error in my vuejs webApp, hope some one tell me how to solve it:

this is the script in my vue file:

I assume you have installed firebase via a node package manager using npm command. If so, the following import statement should fix the problem.
import { db } from 'firebase'
I'm trying to define parsers in a build.sbt file.
I'm using this plugin, by adding this line in plugins.sbt:
addSbtPlugin("com.gilt" % "sbt-dependency-graph-sugar" % "0.7.4")
When specifiying this in build.sbt:
import sbt.complete.DefaultParsers._
val servers = token(
literal("desarrollo") |
literal("parametrizacion")
)
SBT complains with this error message:
reference to literal is ambiguous;
reference to token is ambiguous;
it is imported twice in the same scope by
import sbt.complete.DefaultParsers._
and import _root_.gilt.DependencyGraph._
How can I avoid this namespace clashing of basic SBT classes?.
One solution is this:
import sbt.complete.{DefaultParsers ⇒ DP}
import sbt.complete.DefaultParsers._
val servers = DP.token(
DP.literal("desarrollo") |
DP.literal("parametrizacion")
)
I don't fully like it, because it adds clutter.
The ideal solution is to hide unwanted imports.
This solution creates a new scope, so there's no interference with imports:
name := "MyProject"
{
import sbt.complete.DefaultParsers._
val servers = token(
"desarrollo" | "parametrizacion"
)
}
