ruby-on-rails - 你的 Ruby 版本是 2.3.0，但是你的 Gemfile 指定了 2.1.2

Question

我正在尝试设置一个现有项目，运行 bundle install 时，出现以下错误。

我已经尝试了很多可能的解决方案，但对我没有用，我也运行了建议的命令，比如 gem pristine bcrypt --version 3.1.10 但对我。

    bipashant@bipashant-Inspiron-5537:~/sanokam$ bundle install

    Ignoring bcrypt-3.1.10 because its extensions are not built.  Try: gem pristine bcrypt --version 3.1.10

    Ignoring ruby-prof-0.14.2 because its extensions are not built.  Try: gem pristine ruby-prof --version 0.14.2

    Your Ruby version is 2.3.0, but your Gemfile specified 2.1.2

更新1

bipashant@bipashant-Inspiron-5537:~/sanokam$ rvm list

rvm rubies

=* ruby-2.1.2 [ x86_64 ]
   ruby-2.3.0 [ x86_64 ]
   ruby-2.3.1 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

我还有一个 ruby 版本的 Gemfile。

source 'http://rubygems.org'

ruby '2.1.2'

任何建议将不胜感激，谢谢。

您的 Gemfile 可能有这一行:

ruby '2.1.2'

并且您使用的是 ruby​​ 2.3.0，因此您可以:

1. 在 rvm/rbenv/chruby 的帮助下切换到 ruby​​ 2.1.2
2. 将您的 Gemfile 更新为 ruby '2.3.0' 并再次 bundle install
