Angular CLI安装报错errno -13（EACCES权限问题），求解决方法

Hey Wei, that EACCES error is a super common hiccup when installing global npm packages—basically, your user account doesn’t have write permissions to the default global node_modules folder at /usr/local/lib/node_modules. Let’s walk through a few safe, practical fixes:

Option 1: Temporary Sudo Install (Quickest Short-Term Fix) #

If you just need to get Angular CLI installed right away, you can run the command with elevated privileges:

sudo npm install -g @angular/cli

Just enter your system password when prompted. Note: Packages installed this way will require sudo for future updates, and might cause file permission quirks down the line.

Option 2: Change Ownership of npm’s Global Directories (Recommended) #

This adjusts permissions so your regular user owns the directories npm needs to write to, eliminating the need for sudo entirely:

1. First, confirm npm’s global prefix directory:

   npm config get prefix
   

   This should return /usr/local for your setup.
2. Update the owner of the relevant subdirectories to your user:

   sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}
   

3. Now you can run the original install command without issues:

   npm install -g @angular/cli
   

Option 3: Use a Custom Global npm Directory (Most Secure) #

If you don’t want to modify system directory permissions, set up a dedicated global folder in your user directory:

1. Create the custom directory:

   mkdir ~/.npm-global
   

2. Configure npm to use this directory as its global prefix:

   npm config set prefix '~/.npm-global'
   

3. Add the custom directory’s bin folder to your shell’s PATH (so your system can find globally installed tools like ng):
   • Open your shell config file (e.g., ~/.bashrc for Bash, ~/.zshrc for Zsh):

     nano ~/.bashrc
     

   • Add this line at the end:

     export PATH=~/.npm-global/bin:$PATH
     

   • Save and exit, then refresh the config:

     source ~/.bashrc
     

4. Now install Angular CLI normally:

   npm install -g @angular/cli
   

Quick Side Note #

Your Node.js version (v8.11.1) is quite outdated—newer versions of Angular CLI may not support it. If you run into additional errors after fixing permissions, consider upgrading Node.js to a supported LTS version (like 14.x or 16.x) to ensure full compatibility.
