对于旧的rails应用程序，奇怪的rails错误“权限被拒绝：bin / rails”
每当我运行rails （或任何rails命令）时，我都会收到此错误_rails_command:2: permission denied: bin/rails仅当我在一个旧的 rails应用程序目录中时。
在这些目录中， bundle exec rails c命令可以工作但是rails甚至rails -v不起作用。
背景：我将编码工作区保留在dropbox文件夹中。 现在我最近安装了Manjaro，因此我从之前的操作系统中下载的所有rails应用程序都称之为旧的 rails应用程序。
简而言之：除了旧的rails应用程序外，Rails 在任 bundle exec rails c工作正常。 我试过的Ruby版本： 2.0.0 (rvm), 2.1.1(rvm), 2.1.1 (system)

更新 ：它在bash中运行良好，问题似乎与oh-my-zsh有关。
这是我的rvm-info（来自zsh）：

在你提到的目录中是你的可执行模式的rails。 如果没有，你可以申请
chmod u+x bin/rails
并使其可执行。
跑
bundle exec rake rails:update:bin
它将更新bin / rails和bin / rake文件。
我有同样的问题，这是帮助我的。 打开〜/ .zshrc并添加它
export PATH="$HOME/.rbenv/bin:$PATH" eval "$(rbenv init -)"
当我尝试使用rails 4.0版本时，我有这个。 所以当我尝试将bundle exec放在第一位时，例如：
bundle exec rake db:migrate
要么
bundle exec rails s
作品。
