'react-native ios Podfile issue with "use_native_modules!"

In my react-native project ([email protected]) in the ios/ dir I run pod install and get this error:

[!] Invalid `Podfile` file: no implicit conversion of nil into String.

 #  from /Users/coryrobinson/projects/hhs2/ios/Podfile:37
 #  -------------------------------------------
 #  
 >    use_native_modules!
 #  end
 #  -------------------------------------------

I haven't added or changed anything in this Podfile - it's all react-native generated. (I'm not experienced in iOS dev so this might be a simple fix, I just don't know what to look for :-|) Thanks for any help!

Here is my Podfile

platform :ios, '9.0'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

target 'hhs2' do
  # Pods for hhs2

Downgraded @react-native-community/cli-platform-ios from 3.1.0 to 3.0.0 and it worked.

Added

"@react-native-community/cli-platform-ios": "3.0.0"

to package.json.

Run npm install and then pod install to get it working again.

Solution 2:^[2]

If you are using

pod install --project-directory=ios

you might need to tweak the Podfile by replacing

use_native_modules!

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

Solution 3:^[3]

i just dropped the whole node_modules and RN cache folder and did a clean reinstall, this fixed the "use_native_modules" problem so far....but after that i had to hassle a lot with other libs which where just not RN0.60 ready ;)

Solution 4:^[4]

Verify if you have @react-native-community/cli-platform-ios in your package.json,

if you dont run:

npm install @react-native-community/cli-platform-ios

then

cd ios && pod install

Solution 5:^[5]

this is because the outdate yarn version on your device, if you on macOS you can upgrade/install the yarn with follow this link: here it is

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

Solution 6:^[6]

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.

Solution 7:^[7]

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.

Solution 8:^[8]

Don't use yarn install. Thats what worked for me...

Go to main folder
Delete nodes folder
Run sudo npm install or just npm install
cd ios
pod install

Having same issue while building app on AppCenter, locally works perfectly

Is there any possibility to track this error? Cause I've seen that there can be a lof of reasons why I see it.

Solution 10:^[10]

After removing several react-native npm packages (ie: react-native-bluetooth-serial, react-native-sound, and more...) pod install works.

It appears the pod install error is related to older react-native packages that don't support cocoa pods? I'm not sure the details but removing those packages from node_modules & package.json solved my issue.

Solution 11:^[11]

The issue is that:

use_native_modules!

is unsupported by earlier versions of CocoaPods. For example, our install was the app downloaded from the CocaoPods website. That version is 1.5.2.

Run:

pod --version

to check which version. If need be, uninstall and then re-install but in Terminal by running:

sudo gem install cocoapods

At least as of late October 2019, the current gem version available is 1.8.4. Once successfully installed, re-attempt the pod install and hopefully all is well.

Solution 12:^[12]

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.

Solution 13:^[13]

This started happening out of the blue today, and the problem was a space in my directory structure. Ex:

/path/to/Directory\ Name/RNProject throws the !native_modules error /path/to/DirectoryName/RNProject works as it should

Pods was looking for "Directory. "

Solution 14:^[14]

maybe its related to rights issues

adding "@react-native-community/cli-platform-ios": "3.0.0" in package.json

and

sudo chown -R user .

worked for me

Solution 15:^[15]

Got it working based on a blog post from one of JavaScript Guru's.

Easily:

Run sudo xcode-select --switch /Applications/Xcode.app in the root of your React Native project.
In the ios folder run pod install.

Edit:

No hacks with any of:

@react-native-community/cli-platform-ios
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

were needed.

Solution 16:^[16]

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.

https://help.learn.co/en/articles/2789231-how-to-upgrade-from-ruby-2-3-to-2-6

Solution 17:^[17]

Does anyone have a consistently recreatable solution for this issue that does not revolve around getting rid of use_native_modules? I have looked into:

Changing Ruby Version
Changing CocoaPods version
Invalidating NPM and Cocoapods cache

And I am unable to fix the issue. It appears to be some npm dependency, but others on my team are not seeing it.

Solution 18:^[18]

Getting rid of the line use_native_modules! works as well. Maybe this has been deprecated or syntax has changed? Curious to hear from others.

Update: Seems to be an issue with react-native 0.60.0. Until a release fixes this bug, 0.59.10 can be explicitly installed, and you only need to add CocoaPods as necessary.

react-native init APP_NAME --version [email protected]
