Current behavior:

On travis CI, when using image xcode11.5 which comes with CocoaPods v1.9.2, when running

ionic cordova platform add ios

prints the following at some point :

Failed to install 'cordova-plugin-firebasex': Error: cocoapods version is invalid - please reinstall cocoapods@^1.9.0: Resolving dependencies...

1.9.2

cordova-plugin-firebasex: Preparing Firebase on iOS

[ERROR] An error occurred while running subprocess cordova.



        cordova platform add [email protected] exited with exit code 1.



        Re-running this command with the --verbose flag may provide more information.

In spite of this error, though, the build carries on.

Expected behavior:

The plugin should be installed properly as 1.9.2 complies with ^1.9.0.

Steps to reproduce:

Not 100% sure if this is related to Cocoapods version or the Travis environment.

In there, running

pod --version

prints out

1.9.2

Other information:

I believe the install fails because of the code in

https://github.com/dpa99c/cordova-plugin-firebasex/blob/cee0c4e9e28c5680191ce04ba5a0952a47133b19/scripts/ios/before_plugin_install.js#L10-L23

That code expects the output of pod --version to be a single-line string with a version number (which seems like a valid assumption) , but it therefore fails to parse this multiline string

Resolving dependencies...
1.9.2

One option might be to be a bit more laxist, and expect the version number to be on the last line of the stdout, and just validate that part.

Update : I could also reproduce it on a different Travis image (XCode12) which comes with Cocoapods v1.9.3 (the latest I believe)

pod --version

also prints

Resolving dependencies...
1.9.3

and therefore the build shows the same message :

Failed to install 'cordova-plugin-firebasex': Error: cocoapods version is invalid - please reinstall cocoapods@^1.9.0: Resolving dependencies...

1.9.3

Maybe the best approach is to use a regex to extract the version number from the stdout before comparing it with semver:
/\d+\.\d+\.\d+/
