What / Why
npm link ../doesnt-exist, which is completely invalid syntax, gives a weird error:
npm ERR! code EINVALIDTYPE
npm ERR! typeerror Error: Argument #2: Expected array but got string
npm ERR! typeerror at EventEmitter.install (/home/faux/.npm-packages/lib/node_modules/npm/lib/install.js:195:3)

When
Always, even outside a project, target path is valid or not, etc.
I do have linked projects on my system, and a registry, and a cache, and a prefix.
//registry.npmjs.org/:_authToken=${NPM_TOKEN}
cache=/home/faux/.cache/npm
prefix=/home/faux/.npm-packages
Expected Behavior
I had remembered that this was the syntax to link the module at a path. It is not.
I don't even think it should be. I just happened to run it.
I meant to run:
cd ../doesnt-exist
npm link
cd -
npm link doesnt-exist
