请教一下，为什么我的 yarn 连接不上 https://registry.yarnpkg.com， timeout error

[yazoox]

我输入 create-react-app myapp --typescript

然后得到下面的错误提示

google 了一下，什么--timeout=999999，重启机器，设置 npm registry，node 换成 10.0+，检查 ie 设置，也没有设置 proxy，好像都没有用。还是报一样的错误。

请有经验的大神帮忙看一眼。

系统是 windows10

c:\users<username>\.npmrc 里面，指向国内的地址，应该没有问题吧？

registry=https://registry.npm.taobao.org/
