EACCES errors typically stem from insufficient permissions, often caused by attempting to install global packages. Here's what you need to do to fix it:
Step 1: Identify the problematic directory. Before diving into a solution, pinpoint the source of the problem. Run the following command in your terminal:
npm config get prefix
Take note of the directory that appears - the issue's root.
Step 2: Create a new directory for global packages. Instead of modifying permissions for the problematic directory, we'll create a new directory to store global packages. Execute the following command:
This generates a new directory called "npm-global" within your home folder.
Step 3: Configure NPM to use the new directory. With our new directory in place, let's tell NPM to utilize it. Run this command:
npm config set prefix '~/.npm-global'
NPM now knows to reference the newly minted directory for global package installations.
Step 4: Update your system's PATH. For your system to find the installed packages, we must update the PATH. Open or create a file called ".bash_profile" (or ".zshrc" if using Zsh) in your home directory:
Add the following line to the file:
Save the changes and exit the editor.
Step 5: Apply the changes to the current session. Lastly, we'll apply the changes to the active terminal session. Run the following command:
Voilà! You have successfully reconfigured NPM to resolve EACCES errors on MacOS. Now, you can install global packages without worrying about those frustrating permission issues.
