Reactjs react应用程序中使用env cmd的问题

系统：

操作系统：Windows 10 IDE:visualstudio代码

我正在开发一个包含以下package.json的react应用程序

{

  },

    "start-dev": "env-cmd -f ./.env.dev react-scripts start",
    "test": "react-scripts test --coverage",
    "eject": "react-scripts eject",

  },

  },

    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

当我在终端npm run start中运行命令时，我面临以下问题：

> env-cmd -f ./.env.dev react-scripts start

其中，当我在任何终端上直接运行env cmd-f./.env.dev react脚本时，我的应用程序工作正常

请提供您的建议。

您是否可以尝试将.env.dev文件放置在与package.json相同的文件夹级别，并尝试通过将其更改为来运行脚本

env cmd-f.env.dev反应脚本启动

---

是的，我尝试过，但问题是“'-f'未被识别为内部或外部命令”，我认为这可能是文件路径的问题。您是否尝试过创建一个默认文件，如“.env cmdrc”，并将其放在项目的根目录中。有关示例，请参阅的RC文件部分。在这种方法中，您不需要使用“-f”。
