换个源试试

#1 楼 @googya 我将 Gemfile 的头一行语句换成了：source 'http://ruby.taobao.org' bundle install 后，出现下面的错误： Fetching gem metadata from http://ruby.taobao.org/. Fetching full source index from http://ruby.taobao.org/ Unfortunately, a fatal error has occurred. Please see the Bundler troubleshooting documentation at http://bit.ly/bundler-issues. Thanks! /usr/local/lib/ruby/site_ruby/1.9.1/rubygems.rb:543:in initialize': not in gzip format (Zlib::GzipFile::Error) from /usr/local/lib/ruby/site_ruby/1.9.1/rubygems.rb:543:innew' from /usr/local/lib/ruby/site_ruby/1.9.1/rubygems.rb:543:in `gunzip'

貌似还是上面类似的错误。

#2 楼 @zhangyuxiu 先运行 gem install 后，出现下列结果：从 Fetching 可以看出，貌似已经找到了要安装的包。 #gem install pg -v '0.11.0' Fetching: pg-0.11.0.gem (100%) ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions into the /usr/local/lib/ruby/gems/1.9.1 directory.

由于权限不够，我以 root 用户重新执行后，仍是得到下面结果：

gem install pg -v '0.11.0'

ERROR: While executing gem ... (Zlib::GzipFile::Error) not in gzip format

我猜想出现这个错误，是不是跟源是没有关系的啊？

#3 楼 @zhangyuxiu 目录名里面可能有中文名了？

你们等等，是服务器没磁盘空间导致异常了，马上就好

#4 楼 @metal 没有中文字符。

#5 楼 @huacnlee 服务器经常出现这种情况么？现在好了么？ 我现在运行，出现的结果是：

gem install pg -v '0.11.0'

你说的服务器，指的是 rubygems 或 taobao.org 源么？

#7 楼 @zhangyuxiu 你现在的问题是 libpq 没有的问题

ruby.taobao.org 现在已经好了的。

#8 楼 @huacnlee 我使用了 yum install libpq 和 yum install libpq-dev , 可是都不成功。你知道怎么解决目前的问题么？
