“BUILD_PATH”未被识别为内部或外部命令

Question

我想在同一台服务器上运行后端服务器和前端。因此，我构建了前端并提供了构建路径，但这不起作用。

这是我的 npm 脚本文件。

{
  "name": "nasa-fe",
  "version": "1.0.0",
  "private": true,
  "dependencies": {
    "arwes": "^1.0.0-alpha.5",
    "react": "^17.0.1",
    "react-dom": "^17.0.1",
    "react-router-dom": "^5.2.0",
    "react-scripts": "^4.0.3"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "BUILD_PATH=../server/public react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": [
      "react-app",
      "react-app/jest"
    ]
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

当我运行构建命令时，它显示“BUILD_PATH”未被识别为内部或外部命令。我该如何解决。

BUILD_PATH 是一个环境变量，就像 PORT 一样。在 Windows 上，使用默认 shell，我们设置 BUILD_PATH 变量的方式是：

设置 BUILD_PATH=../server/public&& 反应脚本构建

这是我更新的脚本文件。

  "name": "nasa-fe",
  "version": "1.0.0",
  "private": true,
  "dependencies": {
    "arwes": "^1.0.0-alpha.5",
    "react": "^17.0.1",
    "react-dom": "^17.0.1",
    "react-router-dom": "^5.2.0",
    "react-scripts": "^4.0.3"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "set BUILD_PATH=../server/public&& react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": [
      "react-app",
      "react-app/jest"
    ]
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}
