Question

我正在我的机构代理后面工作，并且不能使用纱线，它显示

yarn install v1.16.0
info No lockfile found.
[1/4] Resolving packages...
info There appears to be trouble with your network connection. Retrying...

npm install给我这个错误

network tunneling socket could not be established, statusCode=503

纱线版本​​1.16.0；节点版本8.10.0; npm版本3.5.2； ubuntu 18.04.02

我到目前为止所做的事情：

1. 在/etc/apt/apt.conf和/etc/environment中设置代理

   获取：: http ::代理“ http://username:password@proxy:port”;
   获取：: https ::代理“ http://username:password@proxy:port”;
   获取：: ftp ::代理“ http://username:password@proxy:port”;

2. 在.bashrc中设置代理

   export http_proxy =“ http：// username：password @ proxy：port”;
   导出https_proxy =“ http：// username：password @ proxy：port”;
   export HTTPS_PROXY =“ http：// username：password @ proxy：port”
   export HTTP_PROXY =“ http：// username：password @ proxy：port”

3. yarn install --network-timeout 100000

4. 纱线配置集代理http://username:password@host:port
   纱线配置设置https-proxy http://username:password@host:port

5. 使用npm

   npm配置集注册表http://registry.npmjs.org/
   npm config set proxy http://username:mypassword@proxy:port
   npm config set https-proxy http://username:mypassword@proxy:port
   npm config set strict-ssl false
   npm --proxy http://myusername:mypassword@proxy.us.somecompany:8080 --without-ssl --insecure -g install

6. 在https://github.com/yarnpkg/yarn/issues/5259#issuecomment-379769451
中提到了所有这些吗？
7. 所有这些Is there a way to make npm install (the command) to work behind proxy?

他们都没有解决问题。在这种情况下如何使纱线工作？
