折腾：
【貌似无需解决】Mac中active后virtualenv没有生效
期间，
卸载virtualenv出错：
<code>➜ tensorflow pip uninstall virtualenv Not uninstalling virtualenv at /usr/local/lib/python2.7/site-packages, outside environment /Users/crifan/dev/dev_root/tensorflow/venv/bin/.. </code>
virtualenv Not uninstalling virtualenv at

python – How do I remove/delete a virtualenv? – Stack Overflow
然后先去尝试，取消激活试试？
<code>➜ tensorflow deactive zsh: command not found: deactive ➜ tensorflow deactivate </code>
然后好像是可以取消激活了？
不过突然发现：
貌似在active后的tensorflow的图标（从默认的绿色变成）红色，就是已经算是激活了？
如果是的话：
则之前的virtualenv的activate则一直是正常的
-》只不过显示出来的效果不是正常的：
(xxx) $
而是 zsh中右箭头从绿色变成红色
去确认看看
并不是。
然后通过pip list也可以看出：
<code>➜ tensorflow pip list --format=columns Package Version ----------------------------- --------- asn1crypto 0.24.0 astroid 1.5.3 attrs 17.3.0 Automat 0.6.0 backports.functools-lru-cache 1.4 browsermob-proxy 0.8.0 certifi 2017.11.5 cffi 1.11.2 chardet 3.0.4 configparser 3.5.0 constantly 15.1.0 cryptography 2.1.4 cssselect 1.0.1 enum34 1.1.6 hyperlink 17.3.1 idna 2.6 incremental 17.5.0 ipaddress 1.0.19 isort 4.2.15 lazy-object-proxy 1.3.1 lxml 4.1.1 mccabe 0.6.1 parsel 1.2.0 pip 9.0.1 pyasn1 0.4.2 pyasn1-modules 0.2.1 pycparser 2.18 PyDispatcher 2.0.5 pylint 1.7.2 pyOpenSSL 17.5.0 queuelib 1.4.2 requests 2.18.4 Scrapy 1.4.0 selenium 3.7.0 service-identity 17.0.0 setuptools 38.4.0 singledispatch 3.4.0.3 six 1.10.0 speedtest-cli 1.0.7 Twisted 17.9.0 urllib3 1.22 virtualenv 15.1.0 w3lib 1.18.0 wheel 0.30.0 wrapt 1.10.11 zope.interface 4.4.3 ➜ tensorflow </code>
没有进入虚拟环境
否则pip list应该显示为空？
不去管，总之，后来再去删除之前虚拟环境的文件夹后：
<code>➜ tensorflow ll total 8 drwxr-xr-x 16 crifan staff 512B 1 27 13:07 bin drwxr-xr-x 3 crifan staff 96B 1 27 13:06 include drwxr-xr-x 3 crifan staff 96B 1 27 13:06 lib -rw-r--r-- 1 crifan staff 60B 1 27 13:09 pip-selfcheck.json ➜ tensorflow cd .. ➜ virtualenv ll total 0 drwxr-xr-x 7 crifan staff 224B 1 27 13:09 tensorflow ➜ virtualenv rm -rf tensorflow </code>
重新去卸载virtualenv就可以了：
<code>➜ virtualenv pip uninstall virtualenv Uninstalling virtualenv-15.1.0: /usr/local/bin/virtualenv /usr/local/lib/python2.7/site-packages/virtualenv-15.1.0.dist-info/DESCRIPTION.rst /usr/local/lib/python2.7/site-packages/virtualenv-15.1.0.dist-info/INSTALLER /usr/local/lib/python2.7/site-packages/virtualenv-15.1.0.dist-info/METADATA /usr/local/lib/python2.7/site-packages/virtualenv-15.1.0.dist-info/RECORD /usr/local/lib/python2.7/site-packages/virtualenv-15.1.0.dist-info/WHEEL /usr/local/lib/python2.7/site-packages/virtualenv-15.1.0.dist-info/entry_points.txt /usr/local/lib/python2.7/site-packages/virtualenv-15.1.0.dist-info/metadata.json /usr/local/lib/python2.7/site-packages/virtualenv-15.1.0.dist-info/top_level.txt /usr/local/lib/python2.7/site-packages/virtualenv.py /usr/local/lib/python2.7/site-packages/virtualenv.pyc /usr/local/lib/python2.7/site-packages/virtualenv_support/__init__.py /usr/local/lib/python2.7/site-packages/virtualenv_support/__init__.pyc /usr/local/lib/python2.7/site-packages/virtualenv_support/argparse-1.4.0-py2.py3-none-any.whl /usr/local/lib/python2.7/site-packages/virtualenv_support/pip-9.0.1-py2.py3-none-any.whl /usr/local/lib/python2.7/site-packages/virtualenv_support/setuptools-28.8.0-py2.py3-none-any.whl /usr/local/lib/python2.7/site-packages/virtualenv_support/wheel-0.29.0-py2.py3-none-any.whl Proceed (y/n)? y Successfully uninstalled virtualenv-15.1.0 </code>
【总结】
确保退出你的虚拟环境，然后删除掉虚拟环境的文件夹，再去：
<code>pip uninstall virtualenv </code>
即可正常卸载。
