javascript - 如何在 package.json 脚本中运行多个命令？

Question

我正在使用detox用于端到端测试我的 react native 应用程序。当我尝试运行yarn detox build -c android.emu.release时它不能很好地运行脚本 cd android ; ./gradlew assembleRelease app:assembleAndroidTest -DtestBuildType=release ; cd - 。该脚本由 detox init 自动生成.

这是我的package.json文件:

{
  "detox": {
    /*...*/
    "android.emu.release": {
        "binaryPath": "android/app/build/outputs/apk/release/app-release.apk",
        "build": "cd android  ./gradlew assembleRelease app:assembleAndroidTest -DtestBuildType=release ; cd -", //<<<<<<<<<<<
        "type": "android.emulator",
        "device": {
          "avdName": "NexusOneAPI29"
        }
      }
    /*...*/
  },
  /*...*/
}

我正在努力奔跑yarn detox build -c android.emu.release例如。如果

我需要使用哪个符号/字符来连接命令而不是 ;正在排毒？

我认为主要错误是:The system cannot find the path specified.从下面提取。

$ yarn detox-build                                                  
yarn run v1.21.1

您应该使用 && 从 npm 脚本在任何平台和任何 shell 上运行多个命令。您可能认为它在 powershell 上不起作用，但实际上它确实有效。

[npm] doesn't have the exact same semantics for && (it executes the second command regardless of the success of the first), but it does work to string together multiple commands on a line.
