尝试遵循Express入门教程。

我生成了一个应用程序并npm install按照提供的说明运行。

> npx express-generator --view=pug myapp
> npm install
npm ERR! semver.simplifyRange is not a function
npm ERR! A complete log of this run can be found in:

节点的新手，我不知道这意味着什么。看起来是 npm 而不是 Express 的问题？

我尝试运行npm cache clean --force和删除，node_modules但都没有帮助。

如果相关，请使用 npm 版本 7.6.3 和节点版本 15.11.0。
