Question

我目前正在建立基于NODE的项目。我为该项目设计了一个api。当我运行服务器时，api工作正常。因此，在下一步中，我为api编写了一个测试用例。它给了我一个意想不到的结果。我的代码掉到了我的config.js文件中。经过一些调试后，我发现它无法接受来自process.ENV的输入。但是，我不明白为什么不能这样做。我在根文件夹中定义了一个.env文件。我在这里共享我的folder structure，config.js，test.js和.env文件。请检查一下，让我知道我在这里错过了哪些事情。

Answer 1

我通过导出const a: T = { a: false, b: true } delete a.b解决了该问题。我使用的命令是

JWT_SECRET

错误：配置验证错误：子级“ JWT_SECRET”失败，因为[需要“ JWT_SECRET”]
