阿里云Ubuntu 16.04无法建立虚拟环境virtualenv,提示资源不存在

summer_x_sun 2018-03-05 12:22:12 1617

阿里云轻量应用服务器,Ubuntu 16.04系统,pip是最新版本,使用sudo apt install virtualenv成功安装了virtualenv。
当用virtualenv venv命令试图新建一个虚拟环境时,报如下错误。
我查看了常用的几个pypi镜像的均无simple/pkg-resources/路径,故可以排除是镜像连接的问题。
不知有何可能的原因?此问题在阿里云服务器上已出现多次提问列举如下,但均无有效的解决方案。

其它同样的问题有:

Log输出如下:

    可能是阿里云的pypi源有问题,建议换一个源试试。
    pypi的源站在国外,而且不支持rsync同步,因此国内很多源都没同步好。
