How can I fix not working oh-my-zsh plugins - zsh

Question

I've just discovered oh-my-zsh, but I can't get it to work. While themes work just perfectly, plugins do not. I have some plugins selected, eg. macports, but neither I get port command completion nor do appropriate aliases work. Here's my ~/.zshrc:
# Path to your oh-my-zsh configuration.
export ZSH=$HOME/.oh-my-zsh
# Set name of the theme to load.
# Look in ~/.oh-my-zsh/themes/
# Optionally, if you set this to "random", it'll load a random theme each
# time that oh-my-zsh is loaded.
export ZSH_THEME="steeef"
# Set to this to use case-sensitive completion
# export CASE_SENSITIVE="true"
# Comment this out to disable weekly auto-update checks
# export DISABLE_AUTO_UPDATE="true"
# Uncomment following line if you want to disable colors in ls
# export DISABLE_LS_COLORS="true"
# Uncomment following line if you want to disable autosetting terminal title.
# export DISABLE_AUTO_TITLE="true"
# Which plugins would you like to load? (plugins can be found in ~/.oh-my-zsh/plugins/*)
# Example format: plugins=(rails git textmate ruby lighthouse)
plugins=(git osx github macports textmate svn)
source $ZSH/oh-my-zsh.sh
# Customize to your needs...
export
PATH=/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/local/sbin/:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/local/sbin/:/usr/bin:/bin:/usr/sbin:/sbin:/usr/X11/bin:/usr/local/cuda/bin:/usr/local/cuda/bin:/opt/local/bin:/opt/local/sbin
textmate and osx plugins also do not seem to work. zsh complains about unknown command and stops. git and svn have some basic completion but I'm not sure whether it's done by plugin or just a normal zsh completion. Do I have to export something to use those plugins? Or if not, what to do to have that fixed?

Answer 1

Make sure that you define your plugins variable before you initialize zsh:
plugins=(git wd)
export ZSH=/home/<user>/.oh-my-zsh
source $ZSH/oh-my-zsh.sh

Answer 2

I got bitten by this.
What happened is you did a manual install and the instructions for the manual install don't mention that you need to set the PATH yourself.
So you end up with the default PATH. The source for the automatic setup code copies your current path and appends it to the .zshrc, which isn't enough if you depend on non-standard PATH entries (e.g. you run Homebrew on a Mac).
So the fix is simple:
Fire up your old shell and its configuration file and then copy and paste the value of $PATH into the top of your ~/.zshrc file.
Ciao!

I had the same problem just now! There was a package called grml-zsh-config installed in my Archlinux. I removed this package and oh-my-zsh themes started to work.

Answer 4

In my case, in ~/.zshrc I had repeated plugins variable
plugins=(git)
.
.
.
plugins=(git autojump zsh-syntax-highlighting zsh-autosuggestions)
Check to see if this is the case with you because with this only your git plugin will be used.
Remove the first plugins variable and it should work.

I was running into this with the kubectl plugin.
Looking at the contents of ~/.oh-my-zsh/plugins/kubectl/kubectl.plugin.zsh I realized I didn't have the same content as what was on the github repo. Manually updating the file with the contents from the oh-my-zsh repo helped and the plugin started to work. Guess I had to update my oh-my-zsh installation to get the latest plugin content but this worked for me.

Answer 6

In my case,I forgot to add custom plugin name to .zshrc file:
plugins=(customPluginName)
And reload .zshrc:
source ~/.zshrc

Answer 7

make sure the folders of the plugins are located in the ~/.oh-my-zsh/custom/plugins folder. I will advise you are on this directory when you git clone the plugins.
Secondly ensure that you seperate the list of plugins in the ~/.zshrc file with a single space NOT comma.
.
.
.
plugin = (git zsh-syntax-highlighting)
.
.
.
So in the above example, two plugins are added there: git and zsh-syntax-highlighting.

Answer 8

If your .zshrc has this at the top
export ZSH="~/.oh-my-zsh"
try to changing it to:
export ZSH="$HOME/.oh-my-zsh"

Answer 9

Try manually source your plugins like this:
source ~/.oh-my-zsh/custom/plugins/zsh-autosuggestions/zsh-autosuggestions.zsh
Full .zshrc example:
# Which plugins would you like to load? (plugins can be found in ~/.oh-my-zsh/plugins/*)
# Example format: plugins=(rails git textmate ruby lighthouse)
plugins=(zsh-autosuggestions)
source ~/.oh-my-zsh/custom/plugins/zsh-autosuggestions/zsh-autosuggestions.zsh
