我想使用“rake routes”运行我的 rake 命令

但是rails会产生以下错误

** Invoke routes (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!

奇怪的是当我运行“bundle exec rake routes”
时它工作正常！我在开发/生产环境中遇到这个错误

对特定版本的 gem 的依赖会造成先有鸡还是先有蛋的情况，即在应用程序发现它需要不同版本之前，可能会加载错误版本的 gem。 bundle exec有助于右脚下车。见http://yehudakatz.com/2011/05/30/gem-versioning-and-bundler-doing-it-right/

如果你使用 rvm，你可以使用bundle install --binstubs然后你就不必再做 bundle exec 了。有关详细信息，请参阅此帖子。

不要忘记将 bin 目录添加到您的 gitignore 文件中。
