Scripted installations of nvm cannot use sudo npx

[seevee]

Issue

When attempting to run this script on Ubuntu 19.04, I got the following error:

sudo: npx: command not found

This despite having the following:

$ node -v
v12.6.0

$ npm -v
6.10.1

$ npx -v
6.10.1

Solution

I realized that I had installed nvm using their official script. This just adds the nvm shell function into the user's profile (~/.bash_profile, ~/.zshrc, ~/.profile, or ~/.bashrc), which sudo won't have access to.

My solution for the problem, adopted from this StackOverflow post, was to symbolically link my nvm binaries into /usr/local/bin like so:

sudo ln -s "$NVM_DIR/versions/node/$(nvm version)/bin/node" "/usr/local/bin/node"
sudo ln -s "$NVM_DIR/versions/node/$(nvm version)/bin/npm" "/usr/local/bin/npm"
sudo ln -s "$NVM_DIR/versions/node/$(nvm version)/bin/npx" "/usr/local/bin/npx"

Goal

Given nvm's ubiquity and stance towards homebrew installations:

Homebrew installation is not supported. If you have issues with homebrew-installed nvm, please brew uninstall it, and install it using the instructions below, before filing an issue.

This issue might merit either inclusion into the script or a README mention.
