meteor运行android-spawn来自Cordova的ENOENT和gradle错误

Question

I am attempting to run a Meteor project on an Android device and/or emulator. When I run either meteor run --verbose android or meteor run --verbose android-device , I get errors related to Cordova not being able to find certain gradle files. Here's some output from my console:

sarah@sarah-ThinkPad-X220:~/simple-todos$ meteor run --verbose android

Indeed, the files and directories it is trying to access are not there. $ANDROID_HOME/tools/template/gradle/wrapper does not have a directory gradlew

sarah@sarah-ThinkPad-X220:~/Android/Sdk/tools/templates/gradle/wrapper$ ls
gradle

Likewise, there are no files at all in my ~/simple-todos/.meteor/local/cordova-build/platforms/android/gradle/wrapper directory, so there is no gradle-wrapper.properties .

I'm also quite uncertain about the meaning of the spawn ENOENT error.

How can I fix this?

EDIT : I wanted to test that gradle worked at all on my machine, so I made an app in Android Studio and ran it on my phone-- worked fine. My Meteor project still doesn't run on Android, but I think this tells me that gradle is working (somewhere) on my computer.

EDIT : I searched for a gradlew directory on my computer and the only ones I found were in an android-studio , not in my $ANDROID_HOME ( ~\\Android/Sdk ). Not sure what to do with this info, but it seems relevant.

EDIT It occurred to me that the output of gradle -v might be useful:

$ gradle -v

Initial disclaimer: I'm not super familiar with the particular tools you are using on top of the android+gradle, but I'll try to help as best I can.

This is worth reading: https://docs.gradle.org/current/userguide/gradle_wrapper.html

Also, you probably want to get gradle setup on your system first, and double check that gradle home is set (*not always necessary, but depends on what other things like android studio, etc. pull in automagically): https://docs.gradle.org/current/userguide/installation.html

My guess is that the tooling you are using is trying to find the system gradle and/or gradlew it expects to have available within your project...and that it is getting mixed up.
