我正在使用pyenv，virtualenv，'autev`来设置我的虚拟环境。
我安装Python3.5.1，Python2.7.9并创建多个项目虚拟环境。
但是当我激活每个环境并通过which python检查python版本时：它们指向相同的python执行文件：
Python 3.5.1 env （chacha_dabang）Chois @ Chois-MacPro $哪个python
/Users/Chois/.pyenv/shims/python
（chacha_dabang）Chois @ Chois-MacPro $ pip
/Users/Chois/.pyenv/shims/pip
Python 2.7.9 env
（pycon2016）Chois @ Chois-MacPro $（主人）哪个python
/Users/Chois/.pyenv/shims/python
（pycon2016）Chois @ Chois-MacPro $（主人）哪个点子
/Users/Chois/.pyenv/shims/pip
我将目录更改为：/Users/Chois/.pyenv/shims
Chois@Chois-MacPro pyconapac-2016 $ (master)cd ~/.pyenv/shims/
Chois@Chois-MacPro shims $ls

easy_install iptest nosetests pip2 python2.7-config rst2xetex.py
他们有python2和python3 ......
我认为当我设置某个项目的virtualenv时，它本身就应该是这样的virtualenv python：
Chois@Chois-MacPro bin $pwd
/Users/Chois/.pyenv/versions/chacha_dabang/bin
Chois@Chois-MacPro bin $ls
__pycache__ easy_install iptest3 jupyter-qtconsole pildriver.py python rst2xml.py
activate easy_install-3.5 ipython jupyter-serverextension pilfile.py python3 rstpep2html.py
activate.csh enhancer.py ipython3 jupyter-troubleshoot pilfont.py rst2html.py sphinx-apidoc
activate.fish explode.py jsonschema jupyter-trust pilprint.py rst2latex.py sphinx-autogen
coverage f2py3.5 jupyter jwt pip rst2man.py sphinx-build
coverage-3.5 gifmaker.py jupyter-kernelspec nosetests pip3 rst2odt.py sphinx-quickstart
coverage3 ipcluster jupyter-migrate nosetests-3.4 pip3.5 rst2odt_prepstyles.py sqlformat
createfontdatachunk.py ipcontroller jupyter-nbconvert painter.py player.py rst2pseudoxml.py thresholder.py
django-admin ipengine jupyter-nbextension pep8 pybabel rst2s5.py viewer.py
django-admin.py iptest jupyter-notebook pilconvert.py pygmentize rst2xetex.py waitress-serve
因此，当我在which python virtualenv中输入chacha_dabang时，应指向：/Users/Chois/.pyenv/versions/chacha_dabang/bin/python。
我该如何解决？

没问题
当您尝试运行Python时，它首先在当前目录中查找.python-version以确定要运行哪个版本的python。如果找不到此文件，则会查找用户级文件~/.pyenv/version。
您可以使用python --version代替which python。

要更改PYTHONPATH中使用的virtualenv，您必须将此行添加到您的virtualenv的bin/activate文件中：
`export PYTHONPATH =＆＃34; / correct_path /＆＃34;
所以在你的情况下它应该是export PYTHONPATH="/Users/Chois/.pyenv/versions/chacha_dabang/bin/python"
