Error running npm command TypeError: mkdirp is not a function

Question

I already tried to uninstall the Nodejs and reinstall an other version but I keep on getting this error every time I run the command npm install or npm. when I try npm -v it returns the version.

My current installed nodejs versions is 10.16.0 and NPM is 6.12.0.

I had a similar problem, what happened to me was that I changed the version of my node, using a node version manager, I use the "n" https://github.com/tj/n . It turns out that when changing the version I did not see that I had given several error messages "Permission denied", that is, I thought I had changed the version but there was not, that somehow bugged my node and when I tried to use any command with npm it gave mistake.

To solve it, I simply changed the version using sudo, in my case, as I use the "n" node version manager, I ran the "sudo n" command and chose the node version.
