奇怪的导轨错误“权限被拒绝:bin/rails"对于旧的 Rails 应用程序 [英] Weird rails error "permission denied: bin/rails" for old rails apps

问题描述

每当我运行 rails(或任何 rails 命令)时，我都会收到此错误<代码>_rails_command:2: 权限被拒绝:bin/rails仅当我在某个旧 rails 应用程序目录中时.

I'm getting this error whenever I run rails (or any rails command) _rails_command:2: permission denied: bin/rails ONLY when i'm inside some old rails app directory.

在这些目录中 bundle exec rails c 命令有效但 rails 甚至 rails -v 不起作用.

In these directories bundle exec rails c command works but rails or even rails -v don't work.

背景:我将编码工作区保存在 dropbox 文件夹中.现在我最近安装了 Manjaro，因此我从以前的操作系统下载回来的所有 rails 应用程序我都称它们为旧 rails 应用程序.

Background: I keep my coding workspace in dropbox folder. Now I recently installed Manjaro and hence all the rails apps which I downloaded back from my previous OS I call them old rails app.

简而言之:除了旧的 Rails 应用程序外，Rails 在任何地方都可以正常工作.bundle exec rails c 工作正常.我尝试过的 Ruby 版本:2.0.0 (rvm), 2.1.1(rvm), 2.1.1 (system)

In Short: Rails works fine everywhere except for old rails apps. bundle exec rails c works fine though. Ruby versions which I've tried: 2.0.0 (rvm), 2.1.1(rvm), 2.1.1 (system)

更新:它在 bash 中运行良好，问题似乎出在 oh-my-zsh 上.

UPDATE: Its working fine in bash, the problem seem to be with oh-my-zsh.

推荐答案

在你提到的目录中，你的 rails 处于可执行模式.如果没有你可以申请

In the directory you mentioned is your rails in executable mode. If not you can apply

chmod u+x bin/rails

并使其可执行.
