我正在尝试创建一个可以启动反应应用程序然后激活 python 虚拟环境来运行烧瓶服务器的 npm 运行脚本。

package.json 中的脚本：

{
"scripts": {
    "start": "react-scripts start",
    "both": "concurrently \"react-scripts start\" \"cd ../backend && "env/scripts/activate\" && py src/app.py\"",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
}

上面我正在使用concurrently. 但执行both脚本运行反应并给出以下错误：

[1] 'env' is not recognized as an internal or external command,
[1] operable program or batch file.
[1] cd ../backend && env/scripts/activate && py src/app.py exited with code 1

[0] i ｢wds｣: Content not from webpack is served from D:\Work\movielust\frontend\public

我的目录结构是：

main
|___frontend
|   |___package.json
|___backend
|   |___env
|   |___src
|       |___app.py

是否有任何解决方法或这不是真的可能，或者是否有任何其他方法可以同时运行反应和烧瓶？
