Ruby 为什么我得到了一个“答案”；需求安装失败，状态为：1“；RVM错误？

这是我的终端在Macbook Pro、OS X Lion 10.7.5上尝试使用RVM更新Ruby并安装了命令行工具、XCode和自制软件时给我的信息

Error running 'requirements_osx_port_libs_install autoconf automake libtool pkgconfig apple-gcc42 libiconv libyaml libffi readline libksba openssl curl-ca-bundle sqlite3 zlib gdbm ncurses',

有什么想法吗？外派人员？

您的rvm或自制软件安装有问题（您是否安装了自制软件？）。请尝试

rvm get head

和

brew doctor

，然后按照说明进行更新。

我猜这一行很重要：

Error: org.macports.fetch for port expat returned: fetch failed

很明显，代码试图在一堆镜像中搜索该文件。我刚才做的一次快速抽查显示，很多网站都有该文件，所以可能是你们的互联网连接出了问题

require 'httpclient'

clnt = HTTPClient.new

我的错误日志（/.rvm/log）建议我进行brew更新，但我遇到了一个错误：

Error: Failure while executing: git pull -q origin refs/heads/master:refs/remotes/origin/master

日志还说：

Failed to update Homebrew, follow instructions here:
    https://github.com/mxcl/homebrew/wiki/Common-Issues
and make sure `brew update` works before continuing.

这是母性负载！如果您在更新rvm时遇到问题，您可能会在此处找到答案。更新rvm后，我能够安装ruby。

感谢您的回复，并对延迟表示抱歉。我会在方便的时候尽早运行这些程序，并更新下一步的情况。很抱歉延迟了响应。这实际上是有道理的，这里的办公室互联网可能会很受欢迎。我会给srt32的建议更新一个镜头，看看我在那里，只要我有机会。谢谢你的回复！
