This week I upgraded my Macbook to the latest version and since the update, I realized that every time I opened a new terminal I had this warning issue from Oh-my-Zsh.
[oh-my-zsh] Can't update: not a git repository.
If you search a bit, there are several messages explaining that this error may be due to the application folder has been messed up and the .git folder being lost.
It wasn’t my case:
❯ cd .oh-my-zsh
❯ ls -la
...
drwxr-xr-x 14 ruben staff 448 4 nov 10:25 .git
drwxr-xr-x 7 ruben staff 224 4 nov 10:18 .github
-rw-r--r-- 1 ruben staff 102 4 nov 10:18 .gitignore
-rw-r--r-- 1 ruben staff 131 14 abr 2022 .gitpod.Dockerfile
-rw-r--r-- 1 ruben staff 259 14 abr 2022 .gitpod.yml
...The hint to find the fix came when I tried to update oh-my-zsh I got this error message:
❯ omz update
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
Searching a bit more, you can find that the error is due that you have to accept again the license term of the macOS command line developer tools.
To fix it, you just need to run this command:
❯ xcode-select --install
A popup will appear asking if you want to install the tools.
After finishing the installation you should be able to update Oh-my-Zsh and the «Can’t update – not a git repository» won’t appear again.
❯ omz update
Updating Oh My Zsh
