ng: command not found (Angular) error [Solved] #

To solve the error "ng: command not found", install the angular cli package globally by running npm install -g @angular/cli@latest and restart your terminal. If the command fails, run it with sudo and make sure the correct PATH is set in your system's environment variable.

Open your terminal and install the Angular cli globally by running the following command.

Copied!
# 👇️ install angular cli globally
npm install -g @angular/cli@latest

# 👇️ get package version
ng version

# 👇️ create workspace
ng new my-project

# 👇️ run the application
cd my-project
ng serve

Copied!
# 👇️ If you got permissions error, run with sudo
sudo npm install -g @angular/cli@latest

ng version

ng new my-project

cd my-project
ng serve

You can link your project to the globally installed Angular package by opening your terminal in your project's root directory (where your package.json file is) and running the npm link @angular/cli command.

Copied!
npm link @angular/cli

The npm link command creates a symbolic link from the globally installed package to the node_modules/ directory of the current folder.

If that doesn't help, run the following command:

Copied!
npm config get prefix

The command will show you the path where npm puts your globally installed packages. The global packages will be in the bin directory at the specified path.

Look at the PATH environment variable on your operating system and add the path that the npm config get prefix command outputs (if it isn't already there).

If that didn't work, try to add the path to the bin folder (from npm config get prefix) to your PATH environment variable and restart your terminal.

For example, on macOS, you can update your path with the following command:

Copied!
# make sure path matches with npm config get prefix
export PATH=/usr/local/share/npm/bin:$PATH

And on Windows, the output of the npm config get prefix command will look something like: C:\Users\Your_User_Name\AppData\Roaming\npm.

Edit the environment variable on your machine and add the specified path (replacing the placeholder with your username).

If you are on Linux, you can add the output from the npm config get prefix command to your .bashrc file.

Copied!
# 👇️ make sure to update the path with the output
# from the command
export PATH="/usr/local/share/npm/bin:$PATH"

If that doesn't help try to reinstall Node.js on your machine and then install the Angular CLI globally by running npm install -g @angular/cli@latest.

Copied!
# 👇️ install angular cli globally
npm install -g @angular/cli@latest

# 👇️ get package version
ng version

# 👇️ create workspace
ng new my-project

# 👇️ run the application
cd my-project
ng serve

Copied!
# 👇️ If you got permissions error, run with sudo
sudo npm install -g @angular/cli@latest

ng version

ng new my-project

cd my-project
ng serve

Alternatively, you can see how you can fix the permissions error on this page in the official npm docs.
