Cannot find module @jest/reporters when running 'detox test'

Question

Having some trouble getting Detox setup in my React Native project. My project configuration is as follows:

MacOS Version: 10.14.14 Xcode 10.2.1 Command Line Tools: Version 10.2.1

package.json:

        "name": "iPhone XR"
      }
    },

  }
}

Originally I was getting the following errors occurring after installing Jest and Detox as per the instructions in the Setup Guide:

Build system information error: Multiple commands produce '': 1) Target 'double-conversion' (project 'React') has copy command from '/Users/cbrobbel/ProntoProjects/prontopod/ProntoPOD/node_modules/react-native/third-party/double-conversion-1.1.5/src/bignum-dtoa.h' to '/Users/cbrobbel/ProntoProjects/prontopod/ProntoPOD/ios/build/Build/Products/Debug-iphonesimulator/include/double-conversion/bignum-dtoa.h' 2) Target 'double-conversion-tvOS' (project 'React') has copy command from '/Users/cbrobbel/ProntoProjects/prontopod/ProntoPOD/node_modules/react-native/third-party/double-conversion-1.1.5/src/bignum-dtoa.h' to '/Users/cbrobbel/ProntoProjects/prontopod/ProntoPOD/ios/build/Build/Products/Debug-iphonesimulator/include/double-conversion/bignum-dtoa.h'

** BUILD FAILED **

detox[64617] ERROR: [cli.js] Error: Command failed: xcodebuild -workspace ios/ProntoPOD.xcworkspace -scheme ProntoPOD -configuration Debug -sdk iphonesimulator -derivedDataPath ios/build

This was resolved by changing the Build System in XCode to the Legacy Build under Workspace Settings. The following error now appears and I am not sure how to resolve it:

Error: An error occurred while adding the reporter at path "/Users/cbrobbel/ProntoProjects/prontopod/ProntoPOD/node_modules/detox/runners/jest/streamlineReporter.js".Cannot find module '@jest/reporters' at reporters.forEach (/Users/cbrobbel/ProntoProjects/prontopod/ProntoPOD/node_modules/jest/node_modules/jest-cli/build/TestScheduler.js:510:15) at Array.forEach () at TestScheduler._addCustomReporters (/Users/cbrobbel/ProntoProjects/prontopod/ProntoPOD/node_modules/jest/node_modules/jest-cli/build/TestScheduler.js:497:15) at TestScheduler._setupReporters (/Users/cbrobbel/ProntoProjects/prontopod/ProntoPOD/node_modules/jest/node_modules/jest-cli/build/TestScheduler.js:466:12) at new TestScheduler (/Users/cbrobbel/ProntoProjects/prontopod/ProntoPOD/node_modules/jest/node_modules/jest-cli/build/TestScheduler.js:193:10) at /Users/cbrobbel/ProntoProjects/prontopod/ProntoPOD/node_modules/jest/node_modules/jest-cli/build/runJest.js:452:27 at Generator.next () at step (/Users/cbrobbel/ProntoPro jects/prontopod/ProntoPOD/node_modules/jest/node_modules/jest-cli/build/runJest.js:107:30) at /Users/cbrobbel/ProntoProjects/prontopod/ProntoPOD/node_modules/jest/node_modules/jest-cli/build/runJest.js:118:15 at processTicksAndRejections (internal/process/task_queues.js:86:5) detox[64758] ERROR: [cli.js] Error: Command failed: node_modules/.bin/jest --config=e2e/config.json --maxWorkers=1 '--testNamePattern=^((?!:android:).)*$' "e2e"

Any help would be appreciated. Thanks!

Answer 1

如果这是由于对等方依赖性导致的，则可以尝试手动npm install @jest/reporters ，因为对等方依赖性不会自动安装在npm 3以上。

Answer 2

Try running

npm install @jest/reporters 
npm install
