is it because of socks5?

[不只是看看]

Hello, i am using the book Learning Scrapy to learn. i think i follow the step you give to set up the enviroment. i get some wrong. i am using ubuntu 16.0 and i have installed the vagrant 1.8.1 and Oracle VM VirtualBox Manager 5.1.38_Ubuntu and git and Docker version 1.13.1, build 092cba3 into my computer. when i start the command 'vagrant up --no-parallel' in the shell, i got the wrong. I think it may cause by the socks5 proxy which i use for google problem(i am Chinese, and only set up the proxy i can use google), i try to close the socks but it can't work. could you help me? the details as follow:
