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

Answer 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

看起来您已将 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，也可以通过输入 unset XDG_RUNTIME_DIR

取消设置 XDG_RUNTIME_DIR
