ruby-on-rails - Bundler::RubyVersionMismatch: 你的 Ruby 版本是 1.9.3，但是你的 Gemfile 指定了 2.0.0

Question

我正在使用带有 Pow、Ruby、Rails 和一堆有用的 gem 的 Mac。每当我尝试打开我的应用程序时，我最近都会遇到此错误。

Bundler::RubyVersionMismatch:您的 Ruby 版本为 1.9.3，但您的 Gemfile 指定为 2.0.0

我明白这个错误，但我找不到为什么它没有在这里使用正确的版本。

一些有用的信息:

RVM 和 Ruby 版本

$> ruby -v
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin12.5.0]
$> rvm use 
Using /Users/Alex/.rvm/gems/ruby-2.0.0-p247

知道我在这里缺少什么吗？谢谢!

我终于在RVM documentation中找到了解决方案| :

Pow has removed automated detection of rvm, here is how it can be restored by creating .powenv in the root of the project, according to Pow docs it should not be checked in to source control (unless all team members agree on that).

必须将这些行添加到项目根目录下的 .powenv 文件中。然后在重新启动服务器后，一切都很顺利!

# detect `$rvm_path`
if [ -z "${rvm_path:-}" ] && [ -x "${HOME:-}/.rvm/bin/rvm" ]
then rvm_path="${HOME:-}/.rvm"
fi
if [ -z "${rvm_path:-}" ] && [ -x "/usr/local/rvm/bin/rvm" ]
then rvm_path="/usr/local/rvm"
fi

# load environment of current project ruby
if
  [ -n "${rvm_path:-}" ] &&
  [ -x "${rvm_path:-}/bin/rvm" ] &&
  rvm_project_environment=`"${rvm_path:-}/bin/rvm" . do rvm env --path 2>/dev/null` &&
  [ -n "${rvm_project_environment:-}" ] &&
  [ -s "${rvm_project_environment:-}" ]
then
  echo "RVM loading: ${rvm_project_environment:-}"
  \. "${rvm_project_environment:-}"
else
  echo "RVM project not found at: $PWD"
fi
