Flow erroring "cant resolve module" when importing node modules

Question

I recently added this to my flow config due to tons of errors related to node modules that flow picks up

[ignore]
.*/node_modules/.*

This solved those errors, but introduced new one. Now every module I import results in an error where flow says it can't resolve it, hence leading me to think this is due to that ignore rule I added.

Is there a way to fix this because here removing this line just introduces different kind of error, keeping it in still makes it error.

Answer 1

It's a little late now, but for anyone stumbling along this question in the future: you shouldn't ignore your node_modules folder. Flow is supposed to read from that folder and analyze the files inside it.

Answer 2

Actually this is because of the module has no typed definitions. So we can just use flow-typed to create any definition.

1. Run yarn global add flow-typed to install flow-typed globally.

2. Go to project folder: flow-typed install

3. Close your terminal and try to run npm run flow again. That's it.
