当我尝试运行命令'bundle install'或安装特定的gem然后以gzip格式（Zlib :: GzipFile :: Error）发生。 我做了谷歌搜索并找到了一些答案 比如删除缓存，捆绑包但在我的情况下都失败
我正在使用rails 3.2.11和ruby 1.8.7
rubygems line arround 500的代码是
def self.gunzip(data)
require 'stringio'
require 'zlib'
data = StringIO.new data
Zlib::GzipReader.new(data).read
end
##
# Zlib::GzipWriter wrapper that zips +data+.
def self.gzip(data)
require 'stringio'
require 'zlib'
zipped = StringIO.new
Zlib::GzipWriter.wrap zipped do |io| io.write data end
zipped.string
end
而控制台中的错误是
不幸的是，发生了致命错误。请参阅http://bit.ly/bundler-issues处的Bundler故障排除文档。谢谢！
