'CI' 不是內部或外部命令，也不是可運行的程序 或批處理文件

Question

每當我嘗試運行npm run build in react 時，我都會收到以下錯誤：

'CI' 不是內部或外部命令，也不是可運行的程序或批處理文件。

我試過更改版本、彈出、修改 nodejs 路徑、卸載和重新安裝 depedencies 和其他可能的東西，但沒有任何效果。

這是我的.JSON 文件

PS：我有點新反應，我使用 windows 10

Answer 1

“ CI= node scripts/build.js ” 是 linux 操作系統中的有效語法，因此它會顯示錯誤，而不是將腳本更改為：

“腳本”：{“開始”：“反應腳本啟動”，“構建”：“反應腳本構建”，“測試”：“反應腳本測試”，“彈出”：“反應腳本彈出”}，

Answer 2

在“build”鍵腳本下的 JSON 文件中，從值中刪除“CI=”以保留“node scripts/build.js”。同時刪除“build-win”：“set CI=false&&rescripts build”。 最后你的腳本應該看起來像

"scripts": { "start": "react-scripts start", "build": "CI= react-scripts build", "test": "react-scripts test", "eject": "react-scripts eject" },它對我有用

Answer 3

go 到 => package.json 文件“build”：“CI= react-scripts build”，從該行刪除 CL= 或復制粘貼該行

“構建”：“反應腳本構建”，

Answer 4

CI= node scripts/build.js在 Linux 上是有效語法，但在 Windows 上無效。 如果您計划為 Linux 環境或在 Linux 環境上進行開發，則可以使用類似Windows Subsytem For Linux 的東西。

  "scripts": {
    "start": "node scripts/start.js",
    "build": "CI= node scripts/build.js", // <-- This
    "build-win": "set CI=false&&rescripts build",
    "test": "node scripts/test.js"
  },

Answer 5

安裝交叉環境 package 並在 package json 文件中添加交叉環境，如下所示“test:ci”：“cross-env CI=true react-scripts”，

它對我有用
