以前我有这个问题，我删除了所有等于零的变量，并解决了这个问题，也许可以尝试一下。

Add the Node.js-maintained repositories to your Ubuntu package source list with this command:

curl -sL https://deb.nodesource.com/setup | sudo bash -

Then install Node.js with apt-get:

sudo apt-get install nodejs

Optionally we can create a symbolic link for node (for reasons mentioned earlier):

sudo ln -s /usr/bin/nodejs /usr/bin/node

Using this install option, we end up with newer versions of Node.js and npm:

$ node -v

$ npm -v

to check node version and npm version

I suggest installing nvm (node version manager) https://github.com/creationix/nvm

it allows you to install and use ANY node version, and this may be way better, because ubuntu is bound to one specific version. In web development, every project is prepared using dofferen node, so switching it might be necessary
