我是在vmware上開ubuntu寫ruby的，gem的版本為2.2.2。 然而我利用gem安裝package時遇到如下問題(幾天以前沒有該問題)： xxx@xxx-virtual-machine:/tmp$ gem install rmagick --verbose -p GET https://api.rubygems.org/latest_specs.4.8.gz 302 Moved Temporarily GET http://production.s3.rubygems.org/latest_specs.4.8.gz 304 Not Modified GET http://production.s3.rubygems.org/quick/Marshal.4.8/rmagick-2.13.2.gemspec.rz 200 OK GET https://api.rubygems.org/specs.4.8.gz 302 Moved Temporarily GET https://s3.amazonaws.com/production.s3.rubygems.org/specs.4.8.gz 304 Not Modified HEAD http://production.s3.rubygems.org/api/v1/dependencies 404 Not Found GET http://production.s3.rubygems.org/specs.4.8.gz 304 Not Modified ERROR: While executing gem ...
