Can'；t在OSX中升级python dateutil

我正在尝试在OSX上安装Sphinx，希望最终能将其纳入网站，如下所示：

我一直在进行macporting、homebrewing、python wheelin，弄清楚什么是虚拟电视。。。弄清楚我应该使用Python2.7还是3.X（我没弄清楚）

我将此添加到我的bash配置文件中：

export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/site-packages

当我运行此命令时：

python -c "import sys; print('\n'.join(sys.path))"

我原以为它只返回

/usr/local/lib/python2.7/site包

但它说：

/Library/Python/2.7/site-packages/pip-10.0.0b2-py2.7.egg
/Library/Python/2.7/site-packages/virtualenv-15.2.0-py2.7.egg

sudo pip install python-dateutil

pandas 0.22.0 has requirement numpy>=1.9.0, but you'll have numpy 1.8.0rc1 
which is incompatible.
matplotlib 1.3.1 has requirement numpy>=1.5, but you'll have numpy 1.8.0rc1 
which is incompatible.
jupyter-client 5.2.3 has requirement python-dateutil>=2.1, but you'll have 
python-dateutil 1.5 which is incompatible.

无论如何，我最终得到了一个virtualenv设置，并运行了以下命令：

pip install sphinx

我找出了一个小错误，另一个错误是六个。但我无法摆脱以下错误：

jupyter-client 5.2.3 has requirement python-dateutil>=2.1,
but you'll have python-dateutil 1.5 which is incompatible.

当我运行以下命令时：

pip install python-dateutil --upgrade --ignore-installed

我明白了

看起来不错

但当我再次尝试安装斯芬克斯时，我得到了同样的结果

jupyter-client 5.2.3 has requirement python-dateutil>=2.1, but you'll have 
python-dateutil 1.5 which is incompatible.

所以我进去试了以下命令：

sudo rm -rf /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/python_dateutil-1.5-py2.7.egg-info/

我想删除那个目录，到NumPy目录，和另一个dateutil目录…但不能！我没有权限

如果有人对我的sphinx站点使用哪一版本的python（最新版本？）以及如何使用**该版本的python设置虚拟环境有专业的建议，请了解Numpty和dateutil。。。我将永远欠你的债

你可以看到我的numpy也是完全预算的，1.8.0rc1。谢谢。

我猜当安装

python-dateutil

时，无论

pip

指向什么，都是在尝试安装

sphinx

时在其他地方安装软件包。也许可以创建一个干净的virtualenv，激活它，一旦激活，pip就会安装sphinx。嗨，保罗，谢谢。创建virtualenv时应该使用哪些“开关”？我如何确认软件包安装在正确的位置？我试过这个。。。“virtualenv--分发--无网站包captaincoin”
