Report #13144

[bug\_fix] npm ERR\! code EACCES npm ERR\! syscall mkdir npm ERR\! path /usr/local/lib/node\_modules/typescript

Change npm's default directory to one owned by the current user: mkdir ~/.npm-global, npm config set prefix '~/.npm-global', then add ~/.npm-global/bin to the PATH \(e.g., export PATH=~/.npm-global/bin:$PATH in ~/.bashrc\). Alternatively, use a Node version manager like nvm or fnm which handles permissions correctly by installing to the user directory.

Journey Context:
You install Node.js using the official installer on macOS or the NodeSource repo on Ubuntu. Later, you try npm install -g typescript. It fails with EACCES permission denied on /usr/local/lib/node\_modules/typescript. /usr/local is owned by root. You consider sudo npm install \(anti-pattern\). You check the npm documentation and find the guide on fixing EACCES. You create a local directory ~/.npm-global, tell npm to use it as the prefix, and add the bin subdirectory to your PATH. After reloading your shell, global installs work without sudo. You realize using nvm would have avoided this by managing Node in the user directory from the start.
