How to solve zsh compinit: insecure directories issue on MacOS (other solutions failed)

Question

I'm aware there are many copies of this question here, but all of their answers recommend adding

ZSH_DISABLE_COMPFIX="true"

to the top of my ~/.zshrc file. I have done this and still every time I open zsh I am greeted with

zsh compinit: insecure directories, run compaudit for list.
Ignore insecure directories and continue [y] or abort compinit [n]?

It seems that others asking this question didn't have the quotes around the true in the first sample, but I have added that. I have also run source ~/.zshrc Which as far as I can tell reloads the zshrc configuration. This still gives me the above warning. I'm not sure if any of these details could be relevant but I'll include them:

• This is a new zsh installation on an M1 Macbook running Big Sur
• I also have Oh My Zsh installed on top of zsh
• I earlier ran several export commands to set my nvm directory but I don't think that would be relevant

Any idea how to resolve this permissions issue? Thanks

Edit:

compaudit returns

/usr/local/share/zsh/site-functions
/usr/local/share/zsh

Also, here are the other nonstandard entries in my ~/.zshrc file (in order, but there is some built-in stuff inbetween):

ZSH_DISABLE_COMPFIX="true"
export NVM_DIR=~/.nvm
source $(brew --prefix nvm)/nvm.sh
export PATH="/usr/local/opt/icu4c/bin:$PATH"
export PATH="/usr/local/opt/icu4c/sbin:$PATH"
export PATH=$HOME/bin:/usr/local/bin:$PATH
plugins=(git)
source $ZSH/oh-my-zsh.sh
zstyle :compinstall filename '/Users/jonahsaltzman/.zshrc'
# End of lines configured by zsh-newuser-install
# The following lines were added by compinstall
autoload -Uz compinit
compinit

First of all, one problem here is that you run compinit twice: Once through Oh-My-Zsh (when you do source $ZSH/oh-my-zsh.sh) and once manually. You have two options to fix this:

• If you want to keep using Oh-My-Zsh, then you should remove the bottom 3 lines from your .zshrc file.
• If you want to stop using Oh-My-Zsh, then instead, you should remove both plugins=(git) and source $ZSH/oh-my-zsh.sh.

Secondly, note that $ZSH_DISABLE_COMPFIX is specific to Oh-My-Zsh and is not used by compinit itself. It has no effect when you call compinit manually. You can remove it from your .zshrc.

Finally, compinit doesn’t show that warning for nothing. Rather than suppress it, you should instead do chmod g-w,o-w on the directories listed by compaudit. That will fix the problem and make the warning go away.
