我在Red Hat服务器上使用Ruby on Rails.当我尝试生成控制器文件时,我收到此错误:

[ec2-user@ip-172-31-22-128 testApp4]$ rails generate controller welcome

Answer 1

我通过跑步解决了这个问题

sudo chmod -R 1777 /tmp

希望这有助于像我这样的人,他们不想停用弹簧宝石

Answer 2

它需要所有权来为每个服务器启动写入重写pid.

我必须使用我的完整本地路径和sudo来运行它

$ sudo chmod -R 777/Users/MyName/Desktop/projects/my_project/tmp /

Answer 3

我看了一下试图编写pid文件的库lib/spring/env.rb.

有问题的函数尝试每次在同一位置创建一个临时目录,除非XDG_RUNTIME_DIR设置:

path = Pathname.new(File.join(ENV['XDG_RUNTIME_DIR'] || Dir.tmpdir, "spring"))

将所述变量设置为唯一目录对我来说很有用:

export XDG_RUNTIME_DIR=/tmp/`whoami`
