virtualenvwrapper似乎忽略了VIRTUALENVWRAPPER_PYTHON

Question

我是python / virtualenv n00b，並嘗試按照說明安裝virtualenv / virtualenvwrapper.sh。

我通過以下方式安裝了virtualenv和virtualenvwrapper.sh：

pip install virtualenv
pip install virtualenvwrapper

我的系統上安裝了python3.5和python2.7（Mac OS X El Capitan 10.11.4）

當我通過bash搜索python，python3，virtualenv和virtualenvwrapper.sh時，我得到以下信息：

which python ==> /usr/local/bin/python
which python3 ==> /usr/local/bin/python3
which virtualenv ==> /usr/local/bin/virtualenv
which virtualenvwrapper.sh ==> /usr/local/bin/virtualenvwrapper.sh

我將以下行添加到我的.bash_profile中：

export PATH=/usr/local/bin:$PATH
export VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3.5
export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/Devel

源/usr/local/bin/virtualenvwrapper.sh

我的.bashrc文件本質上是空的，而我的.profile源於我的.bash_profile。

當我嘗試使用virtualenvwrapper.sh命令（例如'mkvirtualenv'和'lsvirtualenv'）時，它們可以工作，但是默認的python仍然是python 2.7。

當我運行mkvirtualenv -p python3.5 [name]時，默認python可以正常工作（即python 3.5）。

我究竟做錯了什么？ 為什么virtualenvwrapper可以識別指定的VIRTUALENVWRAPPER_PYTHON？

先謝謝您的幫助。 真的很感激

~~~~我嘗試過： pip3 install virtualenv並出現以下錯誤：

如果有python3命令，則應該有pip3命令。 如果沒有pip3，則只能為python 2.x安裝pip。 pip3將安裝到python3，pip將安裝到python。

嘗試使用pip3安裝virtualenv和virtualenvwrapper。
