更新内容：我把fq关了就装上了，问题我输入express -v怎么不能用啊..我已经运行npm install -g express-generator了啊..

Answer 1

看最后你是不是开了代理啊，试试把代理关了再装下

Answer 2

链接下载地址没有成功

Answer 3

这个原因不是很清楚么。

37 error network and is related to network connectivity.

要么被墙了，要么代理有问题。

Answer 4

不要用代理，直接装是能成功的。另外试试升级下npm ，你这个版本太低了。另外你可以检查下node是否正确安装和配置了，如果node配置不正确就是能正常安装组件，但是组件不可用。有两个类似环境变量的文件夹，你看看你配置的对不对。

Answer 5

可能是被墙了吧，不要用npm可以试试淘宝的源来安装
