运行 'detox test' 时找不到模块 @jest/reporters

Question

在我的 React Native 项目中设置 Detox 时遇到一些问题。我的项目配置如下：

MacOS 版本：10.14.14 Xcode10.2.1 命令行工具：版本 10.2.1

package.json:

{
  "name": "AppName",
  "version": "0.1.0",
  "private": true,
  "devDependencies": {
    "babel-preset-react-native-stage-0": "^1.0.1",

  },

  },
  "dependencies": {

      "./src/assets/fonts"
    ]
  },
  "detox": {
    "configurations": {
      "ios.sim.debug": {
        "binaryPath": "ios/build/Build/Products/Debug-iphonesimulator/ProntoPOD.app",
        "build": "xcodebuild -workspace ios/ProntoPOD.xcworkspace -scheme ProntoPOD -configuration Debug -sdk iphonesimulator -derivedDataPath ios/build",
        "type": "ios.simulator",
        "name": "iPhone XR"
      }
    },
    "test-runner": "jest"
  }
}

最初我在按照安装指南中的说明安装 Jest 和 Detox 后出现以下错误：

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

已通过将 XCode 中的构建系统更改为工作区设置下的旧版构建解决了这个问题。现在出现以下错误，我不确定如何解决：

如有任何帮助，我们将不胜感激。谢谢！

Answer 1

如果这是由于对等依赖，您可以尝试 npm install @jest/reporters 手动，因为对等依赖不会自动安装在 npm 3 向上。

Answer 2

尝试运行

npm install @jest/reporters 
npm install

运行 'detox test' 时找不到模块 @jest/reporters

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

javascript

jestjs
