How to: `[oh-my-zsh] theme 'powerlevel10k/powerlevel10k' not found`
When opening a terminal, or starting zsh manually, you may encounter this error message:

```text
[oh-my-zsh] theme 'powerlevel10k/powerlevel10k' not found
```

1. First, run `typeset -p P9K_VERSION` to check whether Powerlevel10k has been loaded.
   - If `typeset -p P9K_VERSION` succeeds and prints something like `typeset P9K_VERSION=1.19.14`
     (the version could be different), remove the following line from `~/.zshrc`:
     ```zsh
     ZSH_THEME="powerlevel10k/powerlevel10k"
     ```
   - If `typeset -p P9K_VERSION` fails with the error `typeset: no such variable: P9K_VERSION`, run
     the following command:
     ```zsh
     git clone --depth=1 https://github.com/romkatv/powerlevel10k.git "${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/themes/powerlevel10k"
     ```
2. Restart Zsh with `exec zsh`.
