plugins is an array used by $ZSH/oh-my-zsh.sh. You need to initialize the former before calling the latter. Just initializing plugins by itself doesn't do anything in Zsh (apart from creating a plain old array).

zsh-syntax-highlighting and zsh-autosuggestions mention explicitly in their documentation that they should be sourced after any other plugins.

Finally, if you're going to manually source a plugin, then you do not need to add it to Oh-My-Zsh's plugins array.

So, therefore, for your setup, this is the correct way to do things:

You're making two mistakes in your .zshrc file:

1. If you do source $ZSH/oh-my-zsh.sh, then you shouldn't also do autoload -U compinit && compinit, because the former includes the latter.
2. plugins=( ... ) should be done before doing source $ZSH/oh-my-zsh.sh. The former does not do anything by itself.

So, change the top of your .zshrc file to this:

Something you do in .zshrc following source ~/.fzf.zsh breaks it. Make sure ~/.fzf.zsh occurs after that, most easily accomplished by moving it to the end of the file.

I was facing a similar issue. I was able to apply the workaround and later on, Jupyter notebook worked as expected.

Alternatively, you can check the path variables as well.

Try removing the npx plugin from plugins=(...) in .zshrc. I had the same problem and that solved it for me.

Use jq's -r option (docs):

It looks like you're trying to use plugins that are not installed. See the following documentation on how to install them:

• zsh-syntax-highlighting
• zsh-autosuggestions

(basically you want to clone the repos into $ZSH_CUSTOM/plugins and source them in your .zshrc, but see the documentation of each for actual commands to use. NOTE: zsh-syntax-highlighting must be the last plugin sourced.)

The other part of your question is answered in your terminal output:

To fix your permissions you can do so by disabling the write permission of "group" and "others" and making sure that the owner of these directories is either root or your current user.

It looks like the owner is already your current user, however your permissions are rwxrwxr-x, which are read, write, execute for users and group, and read, execute for others. From the warning message you should remove the write permission from group:

To fix the first issue try moving zsh-syntax-highlighting to the very end of plugins. From zsh-syntax-highlighting FAQ:

Why must zsh-syntax-highlighting.zsh be sourced at the end of the .zshrc file?

zsh-syntax-highlighting.zsh wraps ZLE widgets. It must be sourced after all custom widgets have been created (i.e., after all zle -N calls and after running compinit). Widgets created later will work, but will not update the syntax highlighting.

To fix the second issue add the following at the end of ~/.zshrc:

Somewhere you're sourcing the whole of the bash_completion project - don't. Bash completions don't work in zsh and even if they did, they are worse than the native zsh ones. bashcompinit is only useful with individual, carefully selected and tested functions. But is still better avoided.

It isn't clear where it is being sourced. The syntax highlighting plugin is unlikely. oh-my-zsh shouldn't be doing it either but I'd try disabling it first. Also check other startup files like .zshenv, .zlogin, .zprofile and system files such as /etc/zshenv.

Also, regarding the .zshrc you quoted: there's no need to pass +X to autoload, that's pointless. The second assignment to the plugins array is replacing the value from the first assignment. Did you want += instead? And if you want $ for a a normal user in the prompt and # for root, you can do that directly with %(!.#.$)
