Flow: Flow cannot resolve modules when run on the same project on a different computer

[jamesqo]

I'm using Flow version 0.72.0 for my project. On my Windows laptop, running flow works fine; however, on my desktop I'm getting a could not resolve module error for every import that I have. Both relative (import _ from './search_screens';) and absolute (import _ from 'react-native';) imports seem to raise this error. Is there anything I could be doing wrong?

Here's what my .flowconfig looks like (basically the same as the default React Native one but w/ a few changes):

[ignore]
; We fork some components by platform
.*/*[.]android.js

; Ignore "BUCK" generated dirs
<PROJECT_ROOT>/\.buckd/

; Ignore unexpected extra "@providesModule"
.*/node_modules/.*/node_modules/fbjs/.*

; Ignore duplicate module providers
; For RN Apps installed via npm, "Libraries" folder is inside
; "node_modules/react-native" but in the source repo it is in the root
.*/Libraries/react-native/React.js

; Ignore polyfills
.*/Libraries/polyfills/.*

; Ignore metro
.*/node_modules/metro/.*

same here

Could either of you provide a minimal repo where this error can be reproduced? Also, are both computers running the same version of windows?

[zenz]

@mrkev just create a new app with react-native init with version 0.55
then add all libraries needed, then run yarn run flow, will get the issue.

my env is windows 10, node 8

[mrkev]

If the error works on one computer but not the other, I'd rather download a repo that I know is problematic rather than try to repro myself. There's 2000+ other issues to dive into, trying to manually repro each one doesn't scale ¯\_(ツ)_/¯

[zenz]

@mrkev you are right, today when I re do the creation and test. the problem gone! no special treatments, it just pass all test. so maybe some libs changed or update make affects.

[mrkev]

Hmmm interesting. Yeah, I'll call this issue closed (:

TRY

/path/to/project/node_modules/.bin/flow stop
/path/to/project/yarn run flow (or your flow invoking script)
