TypeError: cacheDir is not a function

[domharrington]

I got this error when testing out the API module on our reference guide: https://docs.readme.com/developers/reference/projects

const sdk = require('api')('https://docs.readme.com/developers/openapi/5e1a4f6284248b0018149174');

sdk.getProject()
  .then(res => res.json())
  .then(res => {
    console.log(res);
  });

I saved it to /tmp/node-simple.js and ran npm install api, then ran node node-simple.js and got the following error:

$ node node-simple.js
/private/tmp/node_modules/api/src/cache.js:17
    this.dir = cacheDir();
               ^

Confusingly when it's in another directory it works as intended? Could this be an error in running from /tmp? I use it exclusively for messing around with stuff like this.

Interesting, it looks like the find-cache-dir module we're using for locating the cache dir returns nothing if it can't find the modules dir: https://github.com/avajs/find-cache-dir/blob/master/index.js#L44-L67

I definitely have the module installed:

$ npm ls api
/private/tmp
└── api@2.2.0

And there's a /tmp/node_modules dir too.

Will look into it, maybe its a bug in find-cache-dir.

Able to replicate this when not running the library out of /tmp.

Seems this happens when there's no package.json file in the directory that has api installed.
