我可以隐藏或静音“npm ERR！"吗?使用 npm run 脚本时的输出? [英] Can I hide or silence "npm ERR!" output when using npm run script?

问题描述

我正在使用 npm run script 来执行诸如构建"和测试".

I'm using npm run script to do tasks such as "build" and "test".

例如，我的 package.json 如下所示:

For example, my package.json looks like the following:

{
  "name": "fulfillment-service",
  "version": "1.0.0",
  "description": "Endpoint for CRUD operations on fulfillment status",
  "main": "src/server.js",
  "scripts": {
    "build": "tsc",
    "test": "tape tests/*.js"
  },
  "dependencies": {},
  "devDependencies": {
    "typescript": "^1.8.10"
  }
}

当我运行 npm run build 并且成功时，输出如下:

When I run npm run build and it is successful, the output is the following:

> fulfillment-service@1.0.0 build d:\code\fulfillment-service
> tsc

当我运行 npm run build 并且失败时，输出如下:

When I run npm run build and it fails, the output is the following:

> fulfillment-service@1.0.0 build d:\code\fulfillment-service
> tsc
src/server.ts(51,81): error TS2339: Property 'connection' does not exist on type 'IncomingMessage'.

npm ERR! You can get information on how to open an issue for this project with:
npm ERR!     npm bugs fulfillment-service
npm ERR! Or if that isn't available, you can get their info via:
npm ERR!     npm owner ls fulfillment-service
npm ERR! There is likely additional logging output above.
npm ERR! Please include the following file with any support request:
npm ERR!     d:\code\fulfillment-service\npm-debug.log

这会用无用的信息填满整个控制台，我必须滚动到顶部才能看到它失败的原因.

This fills the entire console with useless information, and I have to scroll to the top to see why it failed.

无论如何在开发过程中隐藏/静音以 npm ERR! 开头的行吗?

Is there anyway to hide/silence the lines that start with npm ERR! during development?

推荐答案

必须使用npm run build --silent.

You have to use npm run build --silent.

这在 npm help、npm help run 或任何其他明显的东西中没有记录，但是通过在互联网上进行一些搜索，您可以发现 显然它记录在 npm help 7 config 中.您还可以在 中使用 loglevel 选项.npmrc.

This isn't documented in npm help, npm help run, or anything else obvious, but with some searching on the internet you can find out that apparently it is documented in npm help 7 config. You can also use the loglevel option in .npmrc.

--silent(简称:-s)选项抑制:

• 以 > 开头的两行表示您正在运行的命令.
• npm ERR! 错误.
• 如果出现错误，则创建 npm-debug.log.

• The two lines beginning with > that say what command you're running.
• npm ERR! errors.
• Creating an npm-debug.log if there's an error.

注意:使用 npm 脚本运行其他 npm 脚本可能需要多次使用 --silent.示例 package.json:

Note: using npm scripts to run other npm scripts may require you to use --silent more than once. Example package.json:

{
  . . .
  "scripts": {
    "compile": "tsc",
    "minify": "uglifyjs --some --options",
    "build": "npm run compile && npm run minify"
  }
}

如果您执行 npm run build 并且 TypeScript 发现错误，那么您将从 两个 脚本中获得 npm ERR!.要抑制它们，您必须将构建脚本更改为 npm run compile --silent &&npm run minify and 使用 npm run build --silent 运行它.

If you do npm run build and TypeScript finds an error, then you'll get the npm ERR! from both scripts. To suppress them, you have to change the build script to npm run compile --silent && npm run minify and run it with npm run build --silent.
