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，没有问题。 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 yarn 代理，但这也不起作用。 如果我尝试这样的事情：'Yarn install' cause 'trouble with network connection' 我什至不能再使用 npm install 了。

这似乎只是您的互联网连接问题。
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。
