The short answer

In some cases, you might end up with a broken installation of npm, preventing you from managing your locally or globally installed packages.

To force reinstall the npm command-line tool on macOS and Linux, you can run the following curl command:

That will fetch and execute the official npmjs installation script.

Once executed, you can verify that the installation was successful by displaying the current version of npm using the -v option flag:

Note that if you're facing incompatibility issues between your npm and node versions, or you simply want to update npm to a higher version, you can read our article on how to update npm globally or per project.

As you might otherwise get the following error message:

You can then remove it from your system using the uninstall command:

Then, reinstall it using the install command:
