duplicate module provider errors when I flow check my project

[jedwards1211]

I swear I've had to tweak flow configs in various projects to ignore these errors about a hundred times by now. It becomes even more of a hassle when fbjs winds up being a transitive dependency. I'm getting really tired of it. I'm including all of them here just so that you guys can experience my suffering.

... 47 more errors (only 50 out of 97 errors displayed)
To see all errors, re-run Flow with --show-all-errors
[nodemon] clean exit - waiting for changes before restart

[sibelius]

you can exclude them on your .flowconfig

[jedwards1211]

I already do,. But I get tired of excluding them over and over as I create new packages

[zpao]

Can you give a quick repro (including flow version)? We don't have many eyeballs here so making it as easy as possible to test is super helpful. Thanks!

[jedwards1211]

@zpao sigh, okay I figured out that it's because I have two versions of fbjs installed. Part of the problem is that yarn f'ed up on the deduplication and I have

$ npm ls fbjs
@pasonpower/[email protected] /Users/andy/pason-power
├─┬ @material-ui/[email protected]
│ └─┬ [email protected]
│   └── [email protected] 
├─┬ [email protected]
│ └── [email protected]  deduped

Yet when I try yarn add --dev @material-ui/[email protected] [email protected] in a fresh project it only installs [email protected].

I need to file an issue with flow to not show these errors on duplicate modules, but is there any chance it would be possible to get rid of the @providesModule annotations that are used for whatever old-school system facebook was using for modules here?

[jedwards1211]

@zpao I read in the node-haste repo that:

Facebook no longer uses node-haste, and this project was not being maintained.

So wouldn't it be possible to remove all of these @providesModule annotations?
