问题
I am trying to following instructions on homebrew homepage but the following
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
returns the following error:
curl: (6) Could not resolve host: raw.githubusercontent.com
Any suggestions?

If you happen to be behind a proxy, You might need a way out, to exit
export http_proxy=http://YOURPROXY:PORT export ALL_PROXY=$http_proxy
For some other users, setting back their github https and https-proxy to default works sometimes as well.
git config --global --unset http.proxy
git config --global --unset https.proxy

You are most probably behind a proxy. Consider running curl command with -k parameter:
-k, --insecure (SSL) This option explicitly allows curl to perform "insecure" SSL connections and transfers. All SSL connections are attempted to be made secure by using the CA certificate bundle installed by default. This makes all connections considered "insecure" fail unless -k, --insecure is used.
See this online resource for further details: http://curl.haxx.se/docs/sslcerts.html
Check also Homebrew docs where they talk about this.

For people facing this problem I had resolved it by adding a new name server into network configuration.
Click on "System Preferences" then "Network", "Advanced" , "DNS", "+" and enter IP of the new name server, a good public name server is "8.8.8.8" .

If non of the above solutions worked and you can't ping https://github.com/ or any other websites with your terminal ,it is because of an application that monitors and controls the access of network , so make sure that your terminal is not blocked from accessing the network by any Firewalls.

It gave an error on the first attempt. However, it was installed on second attempt. The solution is to retry attempting the call.
回答6:
Setting proxy with Username, password and port number worked for me
export http_proxy=http://<MacUser>:<MacPass>@proxy.muc:<ProxyPort>
export https_proxy=http_proxy
After that simply execute
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
