在window下能正常运行，上次复制的时候因为有pkl文件（热登陆记录）所以没有生成二维码没有报错，这次给python改了改，弄了个多开，结果Windows下能正常运行，我是用pycharm敲代码的，敲完部署到linux云服务器，结果linux下没有转那个pkl文件就报错（我是为了让别人登陆的，不可能每次都用pycharm生成对应的pkl文件呀，而且热登陆也会有时效性），报错如下：
Downloading QR code.

查看报错，我是挨着看的，直到看到 File "/usr/lib/python2.7/site-packages/itchat/utils.py", line 83, in print_qr
subprocess.call(['xdg-open', fileDir])，进行尝试才解决问题，打开对应的py文件
[root@host-1 PythonWorkbench]# vi /usr/lib/python2.7/site-packages/itchat/utils.py行数较多，通过：set number添加行数

:set number
查看显示如下：
79 def print_qr(fileDir):80 if config.OS == 'Darwin':81 subprocess.call(['open', fileDir])82 elif config.OS == 'Linux':83 subprocess.call(['xdg-open', fileDir])84 else:85 os.startfile(fileDir)86
猜测可能是调用在linux桌面打开吧（win的时候就是弹出来个二维码图片在桌面），我这个默认ECS阿里云linux服务器，没有那些模块所以报错了，把83行代码注释掉，然后添加个pass,如下：
79 def print_qr(fileDir):80 if config.OS == 'Darwin':81 subprocess.call(['open', fileDir])82 elif config.OS == 'Linux':83 pass84 #subprocess.call(['xdg-open', fileDir])85 else:86 os.startfile(fileDir)87
然后再运行，就成功运行了~~~~，刚开始以为没权限创建pkl文件。。。。蛋疼，最后还是一行行看报错~~~本来只看最后一行的报错~~~特此记录下，转载请注明出处~
