我对capistrano相当新，但过去成功使用它没有这么多问题。有谁知道解决这个问题？

Answer 1

我对capistrano相当新，但过去成功使用它没有这么多问题。有谁知道解决这个问题吗？

我想您需要继续使用版本2，修改Gemfile中的行，以便阅读以下内容：

gem "capistrano", "~> 2.15.0"

Answer 2

我遇到了同样的问题，但我必须采取一些措施才能让它发挥作用。首先卸载所有现有版本的Capistrano（如果您有多个版本，请删除所有版本）

sudo gem uninstall Capistrano

然后使用上面给出的文字

为您的回购添加Gemfile

gem "capistrano", "~> 2.15.0"

确保您已安装bundle

sudo gem install bundler

终于安装

sudo bundle install

Capistrano :: Configuration的未定义方法`instance'：`cap deploy：setup`上的类
