yarn 错误There appears to be trouble with your network connection. Retrying

先交代环境:
Ubuntu18
yarn --version
1.22.4
npm -v
6.14.4
node -v
v12.16.3

执行操作后报错信息
#yarn install
yarn install v1.22.4
[1/4] Resolving packages…

error An unexpected error occurred: “https://registry.npm.taobao.org/prettier/download/prettier-2.0.5.tgz?cache=0&other_urls=https%3A%2F%2Fregistry.npm.taobao.org%2Fprettier%2Fdownload%2Fprettier-2.0.5.tgz: unexpected end of file”.

info If you think this is a bug, please open a bug report with the information provided in “/root/zbg_contract_website_h5_app_new/yarn-error.log”.

这里yarn install 过程中会有一个Fetching:
[2/4] Fetching packages…
[################################################################################] 1598/1602

这里有一个校验过程,这个文件你直接放到浏览器里是可以下载下来的。
所以这里使用 yarn add 直接添加这个依赖
yarn add
https://registry.npm.taobao.org/prettier/download/prettier-2.0.5.tgz?cache=0&other_urls=https%3A%2F%2Fregistry.npm.taobao.org%2Fprettier%2Fdownload%2Fprettier-2.0.5.tgz

如图

加载成功了,然后跑yarn install 就很顺利pass了。

另外info提示网络问题,我看网络上绝大部份都是改成淘宝源。这个有可能解决一部分问题,但是还会有一些不管用的。
info There appears to be trouble with your network connection. Retrying…

这里有一个方法:绑定host
直接将绑定源节点 域名+IP写进host
你直接 dig registry.npm.taobao.org

然后将得到的节点IP绑定到host,再执行命令的时候会解决一部分网络的问题。

完!
