大佬教程收集整理的这篇文章主要介绍了ruby-on-rails – Capistrano无法部署代码,因为Net :: SSH :: AuthenticationFailed：Authentication失败，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
今天,当我试图在那里部署一个新的代码时,我被给了这个错误信息：
* 2014-02-16 13:09:51 execuTing `deploy' * 2014-02-16 13:09:51 execuTing `deploy:update' ** transaction: start * 2014-02-16 13:09:51 execuTing `deploy:update_code' updating the cached checkout on all servers execuTing locally: "git ls-remote git@bitbucket.org:my_bitbucket_name/project_name.git master" command finished in 2909ms * execuTing "if [ -d /home/deployer/project_name/shared/cached-copy ]; then cd /home/deployer/project_name/shared/cached-copy && git fetch -q origin && git fetch --tags -q origin && git reset -q --hard 16958dfcee27dd9c33855ecece0013428e2c57c8 && git clean -q -d -x -f; else git clone -q -b master git@bitbucket.org:rdudacz/looky.co.git /home/deployer/looky/shared/cached-copy && cd /home/deployer/project_name/shared/cached-copy && git checkout -q -b deploy 16958dfcee27dd9c33855ecece0013428e2c57c8; fi" servers: ["IP"] *** [deploy:update_code] rolling BACk * execuTing "rm -rf /home/deployer/project_name/releases/20140216120957; true" servers: ["IP"] ** [deploy:update_code] exception while rolling BACk: Capistrano::ConnectionError,connection failed for: IP (Net::SSH::AuthenticationFailed: Authentication failed for user deployer@Ip) connection failed for: IP (Net::SSH::AuthenticationFailed: Authentication failed for user deployer@Ip)
这里发生了什么？从哪里开始寻找问题？
先谢谢你
最后一个版本(2.8.0)会导致此问题.解决方法是卸载它：
gem uninstall net-ssh -v 2.8.0
然后添加到Gemfile其以前的版本：
gem "net-ssh","~> 2.7.0"
而已.
