If you have gotten this error or similar file permission issue on mac you can follow the steps listed in this gist to resolve the problem with node & npm. With this method of installing node you can eliminate using sudo for npm. Please follow along.
For mac here is how node, npm should be installed using nvm. This is the official nodejs.org recommendation for macbook pro. With this approach it eliminates the need of using sudo for npm and file permission issues are automatically addressed.
touch ~/.bash_profile
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash
source ~/.bash_profileExit the terminal and open new terminal & check nvm is installed successfully by running. This prints the version of nvm as 0.33.11.
nvm --version
Next, to see a list of available node versions run this command
nvm ls-remote
Pick the latest version and install node by running
nvm install v10.6.0
nvm use v10.6.0
nvm alias default v10.6.0
nvm current
nvm ls
Exit the terminal. Open a new terminal. Check the prefix value by running
npm config get prefix
If you still see an older location and not the one installed by nvm, then you have to set the new location as latest by running
npm config set prefix /Users/<username>/.nvm/versions/node/v10.6.0
Exit terminal & open again Check versions to see if the node & npm are installed
MacBook Pro:~ vp$ npm -v
6.1.0
MacBook Pro:~ vp$ node -v
V10.6.0
MacBook Pro:~ vp$ npm config get prefix
/Users/<username>/.nvm/versions/node/v10.6.0See locations of node & npm installation directories on the system
MacBook Pro:~ vp$ which node
/Users/vp/.nvm/versions/node/v10.6.0/bin/node
MacBook Pro:~ vp$ which npm
/Users/vp/.nvm/versions/node/v10.6.0/bin/npm
Install angular globally (Note: DO NOT USE sudo for npm)
npm install -g @angular/cli
Change directory to your project project-abc
Remove any existing node_modules directory by running sudo rm -Rf node_modules
Git undo checkout package.json (if in case any previous changes due to npm install exist)
Remove package-lock.json and run these commands to start angular app locally. Add package-lock.json to .gitignore.
npm install
ng s
This runs the angular app on default port 4200.
If you want to run the app at a different port run this
ng s --port 4444
To upgrade npm run this command
nvm install-latest-npm
Nvm has a list of commands that are very useful
MacBookPro:angular-lab vp$ nvm
Node Version Manager
Note: <version> refers to any version-like string nvm understands. This includes:
1. full or partial version numbers, starting with an optional "v" (0.10, v0.1.2, v1)
2. default (built-in) aliases: node, stable, unstable, iojs, system
3. custom aliases you define with `nvm alias foo`
Any options that produce colorized output should respect the `--no-colors` option.
