Aborting installation.

我在公司代理后面工作，但这是设置，我可以通过 npm 安装软件包，例如npm i -g create-react-app ， npm i winston等。 我用谷歌搜索了这个问题并尝试了类似的方法：

yarn install --network-timeout 1000000

我配置了 npm 代理和纱线代理，但这也不起作用。 如果我尝试这样的事情： '纱线安装'导致'网络连接问题'我什至不能使用 npm 安装了。

这似乎只是您的互联网连接的问题。
如果您在 windows 上，请尝试删除临时文件并重新启动路由器。

如果这不能解决您的问题，请考虑重新启动您的机器。 也许它可能会有所帮助。
