i just install the rn-fetch-blob and import it in to the component and it gives me the error
like undefined is not an object RNFetchBlob.DocumentDir.

could you please help me to figure out this bug.

I fixed this by following the instructions on manually linking project rather running react-native link

[Ahsanch11]

i tried it too but the issue is still exists.

[devpascoe]

had this issue because i forgot to rebuild the ios app. Instead was just refreshing simulator but link had added packages so i needed to rebuild and relaunch.

I have same issues on ios.

the automatical linking doesn't work for me.

Maybe it has to be RNFetchBlob.fs.dirs.DocumentDir;

[EgidioCaprino]

We're having a similar issue after upgrading to React Native 0.60 and using auto linking.

This fixed it for me when I ran into this issue on iOS:
(From the project root)
rm -rf ios/Pods && rm -rf ios/build && cd ios && pod install

[Temirtator]

For me solution was gradlew clean and gradlew cleanBuildCache command on AS, then reinstalling of application.

All the solution is for ios, what about the people using react native on Windows. Any suggestions.

in Android->MainApplication.java add these 2 if you are using both after linking..
check if not present, add both:

new RNFSPackage(), new RNFetchBlobPackage()
