Script fails and nukes system-level npm install

[alexdelorenzo]

I tried running the following from the README:

$ wget -O- https://raw.githubusercontent.com/glenpike/npm-g_nosudo/master/npm-g-nosudo.sh | sh

It failed with this error:

sh: line 151: syntax error near unexpected token `)'
sh: line 151: `    [Yy]* ) fix_env;;'

I also tried it with bash and not sh, and got the same result.

After running the command from the README, my npm install was nuked:

$ npm

node:internal/modules/cjs/loader:933
  const err = new Error(message);
              ^

Node.js v17.3.0

I had to reinstall npm, Node and some related packages in order to get a working system npm install again:

$ sudo pacman -S npm nodejs semver node-gyp nodejs-nopt

I'm on Manjaro with npm v8.4.0, Node v17.3.0, Bash v5.1.16 and wget v1.21.2.
