我在打开时遇到这个问题 -> rails 控制台

我使用的是 ruby 版本 2.2.0p0 和 rails 4.2。任何帮助将不胜感激。

【问题讨论】：

sudo chown -R chitra /run/user/gui/spring
取消设置后，问题得到修复unset XDG_RUNTIME_DIR

标签： ruby-on-rails ruby-on-rails-4 ruby-on-rails-3.2

【解决方案1】：

这是引发错误的代码：

# File 'lib/spring/env.rb', line 35

def tmp_path
  path = Pathname.new(File.join(ENV['XDG_RUNTIME_DIR'] || Dir.tmpdir, "spring"))
  FileUtils.mkdir_p(path) unless path.exist?
  path
end

看起来您将XDG_RUNTIME_DIR 设置为/run/user/gui/，但服务器没有对该目录的写入权限。因此，您可以授予对该目录的访问权限，也可以通过键入 unset XDG_RUNTIME_DIR 来取消设置 XDG_RUNTIME_DIR

【讨论】：

或将其设置为您的：export XDG_RUNTIME_DIR=${id -u}.
