在我执行bundle install之后，出现以下错误：

The checksum of /versions does not match the checksum provided by the server! Something is wrong (local checksum is "\"2641a67e9e10afbc8eab003653c63347\"", was expecting nil).

其中，https://gems.ruby-china.org/api/v1/dependencies?gems=hoe%2Catomic%2Cmemcache-client%2Cabstract%2Cracc%2Ctenderlove-frex%2Crake-compiler%2Cweakling%2Crexical%2Cmini_portile%2Ccrass%2Ctest-spec%2Ccamping%2Cfcgi%2Cmongrel%2Cruby-openid%2Cthin%2Crack-cache%2Cjourney%2Crack-mount%2Cactivemodel-globalid%2Cmime-types-data%2Carchive-tar-minitar%2Crcov%2Ctreetop%2Ctlsmail%2Ctext-format%2Cbcrypt-ruby%2Cactiverecord-deprecated_finders%2Crspec%2Cneedle%2Cechoe%2Cjruby-pageant%2Cbcrypt_pbkdf%2Crbnacl%2Crbnacl-libsodium%2Cterm-ansicolor%2Ccolorize%2Cbackports%2Cactive_support%2Crmagick%2Czip%2Crack-ssl%2Cbundler%2Cactiveresource%2Cactionwebservice%2Cactioncable%2Ccolumnize%2Cdebugger-linecache%2Crb-readline 可以下载下来看看是什么东西...

现在我已经暂时切回官方源使用。
