cordova-cli: Unable to "prepare" some projects [9.0.0]

Bug Report

Problem

Running cordova prepare inside a stub project does not create the project correctly.

What is expected to happen?

For a subsequent call to cordova build android to produce an APK.

What does actually happen?

cordova build android will fail with:

Unable to load PlatformApi from platform. Error: Cannot find module 'q'
Unhandled error. (The platform "android" does not appear to be a valid cordova platform. It is missing API.js. android not supported.)

Information

Some of our projects are not restoring correctly when I run “cordova prepare” on them, despite prepare not reporting failure. After some investigation it appears that the root ‘node_modules’ folder is effectively empty (only contains the cordova plugins, not any other dependencies), causing subsequent cordova commands to fail. I haven’t been able to figure out what factor causes the failure as some complex projects seem unaffected but a similar minimal example project seems to trigger the issue. This isn’t an issue on versions of cordova prior to 9.0.0.

Command or Code

Unzip example project stub_project.zip
Navigate to project in terminal
Run the following commands

cordova prepare --verbose

Resulting project: resulting_project.zip

If you repeat this, but remove the line in config.xml that refers to cordova-plugin-whitelist then the project will restore correctly.

@Lindsay-Needs-Sleep there’s a different situation which it happens, even with an existing package.json. I’m in the process of moving to using local packages, specified via the package.json and this issue seems to be happening every time with that change. I’m trying to figure out the magic combination which will allow that to work… But had to move onto other work.

@breautek thanks for mentioning that NPM flag, it might come in handy. It might be the NPM default, but not the cordova. Either way the issue was more that adding a platform would modify the revision of existing dependencies, which is unhelpful if your expecting your server to produce predictable builds.

but it looks like the version numbers in the package.json are being purposefully modified by cordova during the cordova platform add android to include the “^” character.

This is the NPM default. You can edit your npm config to change this, or add an .npmrc file to configure npm specifically for your cordova project. You can change this by modifying the save-prefix config.
