zsh compinit: insecure directories, run compaudit for list
You can list those insecure folders by:
The root cause of "insecure" is these folders are group writable.
There's a one line solution to fix that:
compaudit | xargs chmod g-w
Please see zsh, Cygwin and Insecure Directories and zsh compinit: insecure directories for reference.
I encountered the same problem after following https://docs.npmjs.com/getting-started/fixing-npm-permissions, and I solved it using:
% cd /usr/local/share/zsh
% sudo chmod -R 755 ./site-functions
% sudo chown -R root:root ./site-functions
I found the answer here: https://stackoverflow.com/questions/13762280/zsh-compinit-insecure-directories
I'm using WSL and the above solutions didn't fix it for me, but they did lead me towards this incantation which did fix it:
compaudit | xargs chown -R "$(whoami)"
compaudit | xargs chmod -R go-w
