我想在Windows中（作为Mac的虚拟机）运行React项目。
在命令提示符下，运行yarn以安装依赖项。我做了yarn start。它给了我'HTTPS' is not recognized as an internal or external command错误。
> yarn start
yarn run v1.13.0
$ HTTPS=true CERT=cert/localhost.crt KEY=cert/localhost.key umi dev
'HTTPS' is not recognized as an internal or external command,
operable program or batch file.
error Command failed with exit code 1.

有人知道如何解决此问题吗？
编辑1：
我将节点升级到v12.16.1（yarn升级到1.13.0，npm升级到6.13.4），并执行了yarn add https和yarn add https-localhost。但是，yarn start仍返回'HTTPS' is not recognized as an internal or external command。
[umi dev返回'umi' is not recognized as an internal or external command, operable program or batch file.：
>umi dev
'umi' is not recognized as an internal or external command,
operable program or batch file.
在Windows上，您需要像“ set HTTPS = true”中那样包含“ set”以设置环境变量。
