I uninstalled npm; how do I reinstall?

[wgw]

My npm was corrupt, so I uninstalled it (in Ubuntu : sudo npm uninstall npm -g). Originally, I had installed it from sources (using sudo) and then updated nodejs with npm, but I think the update may have left npm in a corrupt state. At any rate, I had problems using npm install with or without sudo.

What is the best option? Should I try to reinstall npm or just start all over again, with a new install of nodejs? Without npm, it is hard to know where everything is installed! But I do have the original src. Could I do a sudo make uninstall in the src directory (as suggested here: https://github.com/npm/npm)?

You can 'sudo apt-get install npm', or you can reinstall node from source.

Note, when you install from deb or rpm packages, they can place npm in a different location than when you build and install from source. For example on rhel, the rpm installs it to /usr/bin/npm whereas building from source will put it under /usr/local/bin/npm.

Unless you need to deploy lots of servers in a more-or-less automated way, I'd recommend reinstalling node from the source tarball and then 'sudo npm install n' for node version management. Or if you prefer, the nvm node version manager.
