ruby-on-rails - 加载 puma-dev 时，Puma 未使用正确的 Gemset

Question

在运行puma-dev时尝试访问我的 Rails 应用程序时出现以下错误：

unexpected exit:
        from /not/the/correct/ruby/path/ruby_executable_hooks:24:in `<main>'

你如何告诉puma-dev使用正确的路径来加载带有 RVM 的 gem？

Answer 1

我想出了这一点，并想与其他可能正在寻找的人分享。puma-dev使用该.powenv文件加载正确的 RVM 配置。您需要将此文件放在 Rails 应用程序的根目录中：

# .powenv

# 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
