无法安装乘客模块

Question

我正在尝试配置乘客和Nginx for rails应用程序。

执行乘客命令时出现编译错误。

Ruby版本： ruby 2.3.1p112（2016-04-26修订版54768）[x86_64-linux]

Rails版本的 Rails 4.2.6

错误信息：-

# passenger-install-nginx-module
/usr/local/rvm/rubies/ruby-2.3.1/lib/ruby/2.3.0/rubygems/specification.rb:2158:in `method_missing': undefined method `this' for #<Gem::Specification:0x7cab3c passenger-5.0.28> (NoMethodError)

        from /usr/local/rvm/gems/ruby-2.3.1/bin/ruby_executable_hooks:15:in `<main>'

你能不能帮我解决这个问题。

Answer 1

如果尚未解决，您可以尝试：

gem update --system

然后再次尝试编译。

Answer 2

这适用于我的情况：

删除ruby和rvm - 然后重新安装。 再试一次。
