'MONGO_USER' 不是内部或外部命令，也不是可运行的程序或批处理文件

Question

我正在关注 Udemy 上的 NodeJS 教程尝试此代码时出现错误

{
  "name": "nodejs-complete-guide",
  "version": "1.0.0",
  "description": "Complete Node.js Guide",
  "main": "app.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",

  },

    "nodemon": "^1.18.3"
  },
  "dependencies": {

    "pug": "^2.0.3",
    "sequelize": "^5.0.0-beta.11",
    "stripe": "^6.12.1"
  }
}

错误是：

'MONGO_USER' is not recognized as an internal or external command,
operable program or batch file.

运行您的代码来自类 UNIX shell，而不是来自 Windows' cmd.exe。 cmd 无法理解为命令添加变量赋值前缀的语法。

以Git Bash为例。我假设您已经安装了 Git（如果没有，我敢打赌您很快就会安装）。

为了获得更多 Linux-y 环境，我建议首先使用 WSL (Windows Subsystem for Linux) 进行 Web 开发。

对于这种特定情况：您还可以从 start 脚本中删除变量赋值，并在启动应用程序之前手动运行它们，使用 set MONGO_USER=MonkeyKing 等，并记住做每次你打开一个新的 shell （可能创建一个批处理文件）。或者将其移动到 .env 文件中并使用 dotenv 包加载它。
