<强 > 更新

发生这一错误是因为我使用Capistrano, 宝石需要 net- ssh 。 net- ssh 宝石是从2.4 - & gt; 2. 5. 0上更新的,导致问题。

更新我的Gemfile:

gem  rails ,  3.2.0 
gem "net-ssh", "~> 2.4.0"

然后运行 $$ 宝石更新 net-ssh

铁路命令的错误已经消失。 还没有使用 Capistrano 来进行部署, 所以无法说明是否使用部署出现错误 。

<强 > 更新2

Capistrano 无法部署, 因而混乱了 。 使用 < code> cap 部署 时, 我收到您在文章开头看到的错误信息 。

<强 > 更新3

Upgraded net-ssh to 2.5.1 because in the comments someone mentioned 2.5.0 was broken. After the upgrade the require issue was solved, however, Capistrano still will not deploy.

[deploy:update_code] exception while rolling back: Capistrano::ConnectionError, connection failed for: 85.xxx.xxx.xxx (NameError: uninitialized constant Net::SSH::KnownHosts::SUPPORTED_TYPE)
connection failed for: 85.xxx.xxx.xxx (NameError: uninitialized constant Net::SSH::KnownHosts::SUPPORTED_TYPE)

<强>更新4(加工作变通)

在下文的评论中张贴了一个变通办法。

  • Keep your net-ssh version on 2.5.1
  • Before you deploy with Capistrano, delete the line with your server from the ~/.ssh/known_hosts file
  • You can now deploy once. Repeat before every deploy.
问题回答

向2.4.0的降格允许 rails s 工作,但 cap 命令失败 。

通过发布此命令确保您使用 2.5.1 :

bundle update net-ssh

您也可以在您的 Gem 文件中添加此内容 :

gem "net-ssh", "~> 2.5.1"

我认为这是Capistrano宝石的一个错误。我刚刚为我的项目执行了捆绑更新, 并且有同样的错误, 但如果我把Capistrano从Gemfile删除, 一切都会成功的。

UPD:Capistrano宝石使用网状宝石, 这是一小时前更新的。

Gem 2.5.2版本 解决这个问题对我来说。
