静默 npm run-script 失败时的错误 [英] Silencing errors on failures for npm run-script

问题描述

当您运行 npm test 并且失败时，您会得到测试输出 + 一条错误消息，如下所示:

When you run npm test and it fails, you get the test outputs + a single error message, like so:

npm ERR! Test failed.  See above for more details.

但是，我制作了一个名为 lint 的自定义脚本，如下所示:

However, I made a custom script called lint, like so:

// package.json
{
  // ...
  "scripts": {
    // ... definition for test ...
    "lint": "./node_modules/jsxhint/cli.js src/",
  }
}

好吧，很简单.但是当你运行 npm run lint 并且它失败时，而不是 npm test 好看的错误，你会在 linter 输出后得到一个大量的错误消息:

Alright, simple enough. But when you run npm run lint and it fails, Rather than the nice looking error for npm test, you get a massive error message after the output of the linter:

npm ERR! Darwin 14.0.0
npm ERR! argv "node" "/usr/local/bin/npm" "run-script" "lint"
npm ERR! node v0.10.32
npm ERR! npm  v2.1.7
npm ERR! code ELIFECYCLE
# and ~15 more lines...

有没有办法让所有这些垃圾静音，这样我就可以获得像 npm test 脚本一样的干净输出?我看到他们如何在 npm 源代码中发现错误，但我认为我不能只添加一个自定义命令而不像那样分叉 npm ......希望我错了！

Is there a way to silence all this junk so I can have a clean output like the npm test script? I see how they caught the error in the npm source code, but I don't think I can just add a custom command without forking npm like that... Hope I'm wrong!

但如果我是，我是否最好将这样的任务推给 Grunt 之类的工具?谢谢！

But if I am, would I be better off just pushing off a task like this to a tool like Grunt? Thanks!

推荐答案

使用 npm run --silent 选项:

Use the npm run --silent option:

$ npm run --silent test

如果你定义了一个 shell 别名，那么输入就更少了:

Even less typing if you define a shell alias:

$ alias run='npm run --silent'
$ run test
