运行 npm 脚本时如何抑制输出 [英] How to suppress output when running npm scripts

问题描述

我决定尝试使用 npm 脚本作为构建工具，到目前为止我喜欢它.我想解决的一个问题是，在运行脚本以运行 jshint 时，如果某些内容未通过 linting，我会收到大量npm ERR！"线.我想抑制这些，因为 linter 的输出更有意义.

I have decided to experiment with npm scripts as a build tool and so far I like it. One issue I'd like to solve is when running a script to run jshint when something doesn't pass linting I get a ton of "npm ERR!" lines. I would like to suppress these as the output from the linter is more meaningful.

是否有一种全局设置的好方法，以及是否可以为每个脚本运行设置它?

Is there a good way to set this globally and is there a way to set it for each script run?

推荐答案

所有脚本:

您可以通过以下几种方式将日志级别设置为 silent 来整体抑制 npm 的输出来解决此问题:

All scripts:

You can fix this by suppressing the output of npm overall, by setting the log level to silent in a couple ways:

在每个 npm run 调用上:

npm run --silent <your-script>

或者通过创建一个 .npmrc 文件(这个文件可以在你的项目目录或你的主文件夹中)来全局使用以下内容:

Or globally by creating a .npmrc file(this file can be either in your project directory or your home folder) with the following:

loglevel=silent

我用来在某些脚本(如 linting)上解决此问题的一个简单技巧是附加 ||在此类脚本的末尾为 true.这将在没有任何 npm 配置更改的情况下工作.

A simple trick I've used to get around this issue on certain scripts like linting is to append || true at the end of such scripts. This will work without any npm config changes.

这将确保脚本始终以 0 状态退出.这会让 npm 认为脚本成功了，从而隐藏了 ERR 消息.如果你想更明确，你可以附加 ||exit 0 代替，它应该达到相同的结果.

This will ensure that the script will always exit with a 0 status. This tricks npm into thinking the script succeed, hence hiding the ERR messages. If you want to be more explicit, you can append || exit 0 instead and it should achieve the same result.

{
  "scripts": {
    "lint": "jshint || true",
   }
}
