前端[yarnpkg/yarn] There appears to be trouble with your network connection.
近日，我安装完React-Native环境之后，惊讶的发现，yarn用不了了，不知道是安装了RN环境的问题，还是别的问题，yarn也重装了，但是依然没有解决问题。下面放几个解决问题的方法：

方法一：前端[yarnpkg/yarn] There appears to be trouble with your network connection.
1 | yarn install --network-timeout 1000000 //我试了无效 |
方法二：
1、安装好后更换淘宝镜像
1 2 3 4 | yarn config set registry https://registry.npm.taobao.org yarn config delete proxy npm config rm proxy npm config rm https-proxy |
npm 超时
安装cnpm镜像
1 | npm install -g cnpm --registry=https://registry.npm.taobao.org |
使用代理registry
1 | npm config set registry https://registry.npm.taobao.org |
方法三：前端[yarnpkg/yarn] There appears to be trouble with your network connection.
使用npm或cnpm

目前我使用cnpm和npm来进行报的添加。
