zsh: command not found: sanity after reinstalling CLI

This is a classic PATH issue with npm global installations. The zsh: command not found: sanity error means your terminal can't find the globally installed Sanity CLI binary. Here's how to fix it:

Quick Fix

The most reliable solution is to use NVM (Node Version Manager) as it properly manages your PATH configuration:

1. Install NVM if you haven't already:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash

2. Install Node through NVM:

nvm install 16  # or whatever version you prefer
nvm use 16

3. Set default Node version:

nvm alias default 16

4. Reinstall Sanity CLI:

npm install -g @sanity/cli

This should resolve the issue permanently for all new terminal sessions.

Alternative: Manual PATH Fix

If you prefer not to use NVM, you need to add npm's global bin directory to your PATH:

1. Find your npm bin path:

npm bin -g

2. Add it to your .zshrc (note the .bin at the end):

export PATH="/Users/yourusername/node_modules/.bin:$PATH"

3. Reload your shell:

source ~/.zshrc

Using npx as a Workaround

While fixing your PATH, you can always run Sanity commands using npx:

npx -y sanity@latest [command]

The NVM approach is recommended because it handles all the PATH configuration automatically and avoids permission issues with global npm installations. Based on the Sanity CLI documentation, this is a common setup issue that's typically resolved by proper Node.js environment configuration.
