iphone git clone Three20 项目主机无法访问
我只是想在这里执行第一步，了解如何将 There20 添加到我的项目中： Three20
但是，当我运行时在我的终端上：git clone git://github.com/facebook/third20.git，它说：
Cloning into three20...
fatal: Unable to look up github.com (port 9418) (nodename nor servname provided, or not known)
我也尝试过git://github.com/facebook/ Three20。 git，这将打开Xcode 但导致主机无法访问。
我当然可以访问 github.com。
我做错了什么？
I am simply trying to do step one here on how to add There20 to my project: Three20
However when I run this on my terminal: git clone git://github.com/facebook/three20.git, it says:
Cloning into three20...
fatal: Unable to look up github.com (port 9418) (nodename nor servname provided, or not known)
I also tried with git://github.com/facebook/three20.git, this opens Xcode but gives host unreachable.
I can of course access github.com.
What am I doing wrong?

尝试改用 https 协议：
您可能位于防火墙后面，阻止通过 git 协议进行访问。
Try using https protocol instead:
You may be behind a firewall that is blocking access via the git protocol.
您也可以尝试：
我在子模块设置方面遇到了类似的问题。我更改了配置文件，使子模块 URL 采用这种格式，排除协议前缀并将用户名转换为端口号之类的内容。这对我有用。
You can also try:
I had a similar issue with a submodule setup. I changed the config file such that the submodule URL is in this format, excluding the protocol prefix and turning the user name into something like a port number. This worked for me.
