我使用ruby版本2.2.0p0和rails 4.2。 任何幫助，將不勝感激。

Answer 1

這是拋出錯誤的代碼：

# 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

看起來你已將XDG_RUNTIME_DIR設置為/run/user/gui/但服務器沒有對該目錄的寫訪問權限。 所以，你可以授予訪問該目錄，或取消XDG_RUNTIME_DIR鍵入unset XDG_RUNTIME_DIR
