After coming across a similar question with the same headline, I realized that my situation is slightly different.
While setting up a new project, I encountered an issue with installing nodejs. It seemed to only work when using sudo, for example, sudo npm.
I decided to visit this link https://docs.npmjs.com/getting-started/fixing-npm-permissions and executed
sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}in order to change the default directory permissions. Since I had to use sudo npm here as well, I then ran
sudo chown -R $(whoami) $(sudo npm config get prefix)/{lib/node_modules,bin,share}Following this, everytime I try to use sudo, I encounter this error -
sudo: effective uid is not 0, is sudo installed setuid root?
I realize that my setup for npm should have been different and not root, but being new to Linux, I am still learning.
Any assistance would be greatly appreciated. :)
Additional details -
ls -l $(which sudo) gives =>
