I have looked at the trouble shooting page of the wiki, however I still cannot fix the problem I am having.

RN version:

react-native-cli: 2.0.1
react-native: 0.43.4

My code:

import FileUploader from 'react-native-file-uploader'

and

<Button
    onPress={() => RNFetchBlob.fetch('POST', 'http://localhost:8000/upload', {
            'Content-Type' : 'application/octet-stream'
        }, RNFetchBlob.wrap('./tempImageStore/image.jpg'))
    }
    title={'Upload File'}
/>

Error I am getting:

What I did to install react-native-fetch-blob:

1) npm install --save github:wkh237/react-native-fetch-blob-package#master
2) react-native link

Background info:

• I have tried importing it with both import RNFetchBlob from 'react-native-fetch-blob' and var RNFetchBlob = require('react-native-fetch-blob').default
• I have tried installing it with the above code and also with npm install --save react-native-fetch-blob
• I am trying this on the IOS emulator.

Thank you in advance for your help!

So it looks like the module isn't importing. Obvious I know, I can only think of a few things to help seeing as that project looks fairly popular and stable.

I noticed that you're requiring 'react-native-file-uploader' but using 'react-native-fetch-blob'. I'm assuming this is a mistake. You could also try, if you haven't:

var RNFetchBlob = require('react-native-fetch-blob')

Now assuming you're correctly importing it, try one of the following and then restart x-code:

1. If you haven't already restart the packager. I recall having to restart the packager every time I installed a new module.

2. If that doesn't work, try installing deleting it from your node modules (just to be safe) and installing with cocoa pods which will handle all of the linking for you.
