使用 Windows 10，当我运行命令 npm install -g jhipster-uml 时出现以下错误:

谷歌搜索似乎是 npm_config_node_gyp 的 Windows 问题。我尝试使用 npm cli 安装其他软件包并且它有效，所以这很可能是 jhipster-uml 的问题。

我也尝试使用yarn来安装它，我有一个非常类似的错误。

Can't find Python executable "python", you can set the PYTHON env variable.

1. 您必须安装 python 并重新启动 bash
2. 如果 python 已安装，请检查它在您的 PATH 中是否可用。如果没有，只需添加即可。
