Could not automatically link package :TypeError: path must be a string or Buffer

[sujanbasnet]

Hey !

I get this problem while trying to link the library, simple react-native link works but it suggests:

react-native-fetch-blob_ will not automatically add Android permissions after 0.9.4 please run the following command if you want to add default permissions :

RNFB_ANDROID_PERMISSIONS=true react-native link

And when I do RNFB_ANDROID_PERMISSIONS=true react-native link it give me the following error:

RNFetchBlob checking app version ..
RNFetchBlob detected app version => 0.45
Add Android permissions => false
react-native-fetch-blob link FAILED

If I run the project with simple react-native link I get : undefined is not an object (evaluating 'RNFetchBlob.DocumentDir') when the project is run

Versions:

react-native-cli: 2.0.1
react-native: 0.45.1

RNFetchBlob: 0.10.6

It's like your Android project does not exists or not using a default project structure, as a result something went wrong in our prelink script, perhaps you can try to link the library manually.

This is my project structure, I don't know if its the default project structure or not, sorry for my naivety ( this is my first react native project and also my first android application ).

I did try manual installation from the wiki page but I can't seem to find the files you've mentioned in there. Even if I search for lets suppose android/app/build.gradle I get multiple files and I'm not sure which one to update, same case for settings.gradle and MainApplication.java

Again, I have very little idea about android and react native, I'm learning as I go.

okay, so looks like your using expo template. Please read refer to this issue.

Is there an alternative that is compatible with expo?
