please remove @react-native-community/viewpager from package.json,the build success

i'm follow this step:

• in root folder, remove node_modules, yarn.lock
• in root/ios, remove folder Pods
• Then remove @react-native-community/viewpager from package.json
• yarn install
• cd ios && pod install and this error show up
• [!] No podspec found for react-native-viewpagerin../node_modules/@react-native-community/viewpager`

Could you provide your package.json file ? it seems like some dep uses it

I've got the same problem since few days and every time I install a new package.

It only happens on IOS build, not with Android build.

Once in five, after uninstalling and reinstalling everything, the build works, but if you add a new package, the build failed again.

I tried almost everything, deleting node_modules, pods, reinstalling, killing processes etc...

What worked a few times was to do:

• npm install without react-native-pager-view
• pod install
• npm i react-native-pager-view
• pod-install

But the problem comes back with each modification of packages.

My package.json.

The stack trace on build:

EDIT: @ikimiler solution is working for now.
removing @react-native-community/viewpager from package.json

• delete node_modules
• delete Pods and podfile.lock from ios folder
• delete app on client
• npm i (--legacy-peer-deps)
• npx pod-install (or cd ios & pod install)
• npx react-native run-ios

[thanhquang28]

i have done this issue by

• remove node_modules
• remove @react-native-community/viewpager from package.json (many tks to @ikimiler)
• cd ios/ and remove Pods folder, remove Podfile.lock
• delete row pod 'react-native-viewpager', :path => '../node_modules/@react-native-community/viewpager' in Podfile
• back to root folder, yarn install or npm install
• npx pod-install (or cd ios & pod install)
