[记录]CentOS中安装和使用virtualenv

之后,需要再去安装virtualenvwrapper

参考:

virtualenvwrapper 4.7.1.dev15 — virtualenvwrapper 4.7.1.dev15 documentation

http://virtualenvwrapper.readthedocs.io/en/latest/

 jiandaoweixin pip install virtualenvwarpper
DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of pip will drop support for Python 2.6
Collecting virtualenvwarpper
/usr/lib/python2.6/site-packages/pip/_vendor/requests/packages/urllib3/util/ssl_.py:318: SNIMissingWarning: An HTTPS request has been made, but the SNI (Subject Name Indication) extension to TLS is not available on this platform. This may cause the server to present an incorrect TLS certificate, which can cause validation failures. You can upgrade to a newer version of Python to solve this. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#snimissingwarning.

在升级python之前,先要去搞清楚:

[记录]CentOS 6中Python从2.6升级到2.7

重新去安装:

 ~ pip install virtualenvwrapper

就没有警告了。

之前的虚拟环境被删除了。

现在重现去用virtualenvwrapper创建:

 SIPEvents ll

drwxr-xr-x 5 root root 4.0K Aug 15 12:05 SIPEvents

后来断网了

然后再去弄一遍:

 SIPEvents mkvirtualenv SIPEvents
zsh: command not found: mkvirtualenv
 SIPEvents ls $WORKON_HOME
 SIPEvents lsls ~/Envs/ -l

至此,算是环境好了。
