我正在尝试使用为我的计算机科学入门课程提供的库来设置PyCharm，但似乎因为我的python版本，我无法安装PySide，这对于库的导入是必要的。 python --version输出
Python 3.5.1 :: Anaconda 4.0.0 (x86_64)
当我尝试使用pip install pyside安装pyside时收到以下错误：
Collecting PySide
Using cached PySide-1.2.4.tar.gz
Complete output from command python setup.py egg_info:
only these python versions are supported: [(2, 6), (2, 7), (3, 2), (3, 3), (3, 4)]

我已经尝试通过安装pysel并运行sudo pysel 2.7.12将我的python版本更改为2.7，看起来它会受到支持，但这会给我以下错误：
Traceback (most recent call last):
File "//anaconda/bin/pysel", line 9, in <module>
load_entry_point('pythonselect==1.3', 'console_scripts', 'pysel')()
File "//anaconda/lib/python3.5/site-packages/pythonselect-1.3-py3.5.egg/pythonselect/pysel.py", line 287, in main

File "//anaconda/lib/python3.5/site-packages/pythonselect-1.3-py3.5.egg/pythonselect/pysel.py", line 212, in set_curr_python
% (pyver_dir, pyver))
pythonselect.pysel.Error: '/Library/Frameworks/Python.framework/Versions/2.7.12' does not exist: you must install Python 2.7.12
但我确定我安装了python 2.7.12，与此错误消息相反。我尝试重新安装作为完整性检查并确认它已安装：
brew install python
Warning: python-2.7.12 already installed
我已经和它搏斗了好几天了，这让我很困惑。我的想法是Anaconda可能会引起问题，但我不确定。有什么想法吗？
编辑：我已根据您的建议尝试安装pyenv并遇到以下错误。再说一遍，看起来Anaconda正在引发一些冲突。
