Question

我对NPM有疑问。最近，每当我尝试使用npm运行脚本时，它就会给我一大堆错误，即使我知道脚本是正确的，我也无法弄清楚为什么......

的package.json

{
  "name": "testing",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
}

正如您所看到的那样，这只是在运行npm init之后立即生成并且只是输入几次......然而当我运行npm run test时，我得到了这个......

> testing@1.0.0 test C:\Users\user\Desktop\testing
> echo "Error: no test specified" && exit 1

"Error: no test specified"

正如您在错误消息中看到的，我有节点v7.4.0和npm v4.1.2 ...以前我运行的是节点v6.9.2，但是我在收到此错误后仍然更新但仍然没有更改...另外我不知道它是否重要，但我正在运行Windows 10.我已经尝试过npm cache clear解决方案，但这对我不起作用。

这是正常的，当你运行npm run test时，它会在package.json执行相应的脚本，所以这一行

"test": "echo \"Error: no test specified\" && exit 1"

正如您所看到的，它会引发错误并退出，状态代码不是0（exit 1），这是一个错误代码。

您必须通过其他真正运行测试的内容来更改测试脚本。

npm run在尝试运行脚本时总是会出错
