TypeError: requestsById[request.id].push is not a function

I understand this project is no longer actively maintained. I’m just posting this bug report here in case any other users of this project might be able to suggest a fix. 😃

I installed and ran local-npm yesterday and it worked fine. Then this morning when I tried to launch it I got this error message:

~/programs/local-npm > local-npm

Welcome!
To start using local-npm, just run: 

  $ npm set registry http://127.0.0.1:5080

To switch back, you can run: 

  $ npm set registry https://registry.npmjs.org

npm: 2.15.9 node: 4.6.1 local-npm: 1.6.0

From the stack it looks like it’s an issue relating to pouchdb. The version of pouchdb I’ve got installed under local-npm, is 5.4.5

> npm -g ls pouchdb
/usr/lib
└─┬ local-npm@1.6.0
  └── pouchdb@5.4.5

I had the exact same problem, and found a possible solution.

I’ve changed index.js@248 from: if (request.id in requestsById)

to if ((request.id in requestsById) && (Array.isArray(requestsById[request.id])))

Look like the object requestsById sometimes didn’t hold the expected Array.

looks like this was fixed by simply updating pouchdb.
