当我利用vue create demo命令创建项目出现以上问题的时候，我从百度上参考了很多种的方法。

1.网速问题，换一个快的网。

​ 虽然可能存在这样的问题，但是可能性比较小。可以尝试测试一下增加网络超时来判断是否存在这样的情况。

yarn install --network-timeout 1000000

2.代理出了问题，一上来就是这么几条命令。（我也没有通过此方法解决问题）

npm config rm https-proxy

yarn config delete proxy

npm config rm proxy

3.更换镜像，讲yarn的镜像改为淘宝镜像。(当然，也还是没有用。。。)

yarn config set registry https://registry.npm.taobao.org

4.清缓存

npm cache clean --force

5.不知道干啥

npm install chromedriver --chromedriver_cdnurl=http://cdn.npm.taobao.org/dist/chromedriver

Solution

虽然好像也还是一个代理的问题。。。

env | grep -i proxy
#利用全局权限访问配置变量

一查看，果然是这儿的问题，我前几天乱配代理不知道整了什么玩意儿。然后将他们全都清空。就可以顺利创建vue项目了。但是这样只是修改了当前终端的环境变量。否则重新开启一个终端还是没有修改这些值。

https_proxy=
http_proxy=
ftp_proxy=

所以我们需要修改当前用户的环境变量。

vim ~/.bashrc

利用该命令打开文件修改环境变量即可使用到当前用户所有的终端。
