react-native ios Podfile issue with “use_native_modules!”

Question

In my react-native project (react-native@0.60) in the ios/ dir I run pod install and get this error:

[!] Invalid `Podfile` file: no implicit con         


        

Answer 1

I got this error after I tried to react-native run-ios an Expo app. The error I got indicated that something was wrong with the Pods, so I ran cd ios && pod install, which is how I got a similar error as the OP.

In that case, you obviously need to expo start instead of react-native run-ios.

Answer 2

If you are using

pod install --project-directory=ios

you might need to tweak the Podfile by replacing

use_native_modules!

to

use_native_modules!(".")

Maybe this behavior will be improved in the future, I opened an issue about it https://github.com/react-native-community/cli/issues/657

Answer 3

For me, I deleted the node_modules and installed again by using npm install . After that, I navigated to /ios folder and ran pod install it worked.

Answer 4

One of the reasons may be outdated version of Ruby. Use following command to upgrade it.

rvm install 2.6.1
rvm use 2.6.1 --default

Or you can follow below article, which has a detailed explanation of upgrading ruby and associated gems.

Answer 5

Ok, my guess is for most people, the accepted answer will fix their issue. For me, the fix was so bizarre, I had to add it here.

For whatever reason, I ended up creating an invalid AndroidManifest.xml file in my android native setup.

I looked at the full error output, and the first lines of the error referenced a line number and column number. At that point in my xml file I broke the xml formatting.

2 days of searching to find a GitHub Issue with a description of where to look.

be aware to delete node-module and yarn.lock file, install all packages again, navigate to ios folder and run pod install.
