Question

当我在vagrant上运行rails时，我收到以下错误。似乎文件“/home/vagrant/Realarts/tmp/pids/server.pid”不存在，但是rails试图访问它。我该如何解决这个问题？

[vagrant@localhost Realarts]$ rails s 
=> Booting WEBrick
=> Rails 4.2.4 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server

就像Sri提到的那样，Rails需要所有权来在每次服务器启动时编写和重写pid。

您需要确保您的文件夹可以访问，最简单的方法是从VM运行

sudo chmod -R 777 /home/vagrant/Realarts/tmp/

您也可以使用Vagrantfile，例如

config.vm.synced_folder ".", "/vagrant", owner: "vagrant",: mount_options => ["dmode=777"]

Vagrant，权限被拒绝@ rb_sysopen - / home / vagrant
