npm运行<script-name>失败

Question

我想按照开发、分期和生产这样的环境来构建React项目。

下面是package.json文件中脚本部分的快照。

"scripts": {
    "start development": "REACT_APP_ENV=development react-scripts start",
    "start staging": "REACT_APP_ENV=staging react-scripts start",
    "start production": "REACT_APP_ENV=production react-scripts start",
    "build development": "REACT_APP_ENV=development react-scripts build",
    "build staging": "REACT_APP_ENV=staging react-scripts build",
    "build production": "REACT_APP_ENV=production react-scripts build",
    "build": "react-scripts build",
    "start": "react-scripts start",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  } 

因此，根据脚本，“构建开发”应该为开发环境构建项目。现在，当我通过指定环境在项目主目录中运行以下命令时，(为暂存env进行暂存构建)

npm run 'build staging'

下面显示错误并命令退出

> testapp@0.1.0 build staging
> REACT_APP_ENV=staging react-scripts build

sh: 1: /tmp/build: not found

有趣的是，该命令在其他系统上运行非常好，并创建构建文件夹，没有任何问题，但它在我当前的系统上抛出了错误。

我所有的系统都在运行Ubuntu20.04.4LTS

伙计们知道有什么问题吗？

将交叉env添加为依赖项，并更改脚本以使用_而不是空格，如下所示，解决了这个问题

"scripts": {
    "start_development": "cross-env REACT_APP_ENV=development react-scripts start",
    "start_staging": "cross-env REACT_APP_ENV=staging react-scripts start",
    "start_production": "cross-env REACT_APP_ENV=production react-scripts start",
    "build_development": "cross-env REACT_APP_ENV=development react-scripts build",
    "build_staging": "cross-env REACT_APP_ENV=staging react-scripts build",
    "build_production": "cross-env REACT_APP_ENV=production react-scripts build",
    "build": "react-scripts build",
    "start": "react-scripts start",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  }

现在，以下命令在所有平台上运行，没有任何问题。

npm run build_staging
