从 WSL 升级到 WSL2 后

sudo apt-get update

不再起作用。后：

wsl --set-version Ubuntu-18.04 2

输出是：

> sudo apt-get update

这是同一个问题，这里正确回答了jest global variable example，但问题是 Typescript。

console.log(__DEV__);

结果是：

console.log(__DEV__);

全局变量__DEV__在 package.json 中定义为：

  "jest": {
    "globals": {
      "__DEV__": true
    }
  }

有人有解决方案或解决方法吗？

我是骆驼的新手，更喜欢使用 Spring DSL 进行路由定义。现在我发现它令人困惑，http 查询字符串参数被命名和处理为标头，它们不是。这是骆驼的架构错误吗？
