安装 npm 时出现未满足的依赖项错误

Question

When I try to install npm package I am getting unmet dependencies error.

sudo apt-get install npm

I removed usr/lib/node_modules directory and try to reinstall but I am getting same error. Is there any way to handle this?

I am using linux Mint 18.3.

Answer 1

Just uninstall npm and download node from Node JS

Then try to install npm and node again.

I solved same dependency error with re-install.

Answer 2

This is happening because you have by mistake deleted python 2.7.x which is required. Just reinstall node.js and npm using this link and you should be good
