npm run在嘗試運行腳本時總是會出錯

Question

我有NPM的問題。 最近，每當我嘗試使用npm運行腳本時，它就會給我一大堆錯誤，即使我知道腳本是正確的，我也無法弄清楚為什么......

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"
}

正如你所看到的那樣，這只是在運行npm init之后生成的，只是輸入了幾次......然而當我運行npm run test我得到了這個......

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

"Error: no test specified"

正如您在錯誤消息中看到的那樣，我有節點v7.4.0和npm v4.1.2 ...之前我運行的是節點v6.9.2，但是我在收到此錯誤后仍然更新但仍然沒有更改......我也不知道知道它是否重要，但我正在運行Windows 10.我已經嘗試了npm cache clear解決方案，但這對我不起作用。

這是正常的，當你運行npm run test ，它會在package.json執行相應的腳本，所以這一行

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

如您所見，它會引發錯誤並退出，狀態代碼不是0（ exit 1 ），這是一個錯誤代碼。

您必須通過其他真正運行測試的內容來更改測試腳本。
