如何在Mac上为2.7设置python路径？ [英] How to setup python path for 2.7 on mac?

问题描述

我知道，这个问题已经被问过很多次了。但是，我仍然无法摆脱这一点。我在Mac上找到了以下信息。

I am aware that, this question has been asked and answered many times. But, still i couldn't get rid of this. I found out the following info on my mac.

cd /Library/Frameworks/Python.framework/Versions/
Current -> 2.7
3.6

whereispython
/usr/bin/python

which python
/usr/bin/python

which -a python
/usr/bin/python
/usr/bin/python

python
Python 2.7.10 (default) 
[GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.0.59.5)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

即使我编辑〜/ .bash_profile 如下

# Setting PATH for Python 2.7
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"
export PATH

#PYTHONPATH
PYTHONPATH="${PYTHONPATH}:/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python"
export PYTHONPATH

然后，源〜/ .bash配置文件。重新启动Mac&之后终端，仍然可以看到 / usr / bin / python 而不是指向 / Library /../ Python2.7 当执行哪个python 时。

Then, source ~/.bash-profile. After restarting my mac & terminal, could see still /usr/bin/python instead of pointing to /Library/../Python2.7 when executed which python.

我卸载了python，然后重新安装了 pip install python
而且，我还能看到python安装在 /System/Library/Frameworks/Python.framework/Versions

I uninstalled python and re-installed "pip install python" And also, i could see python installed under /System/Library/Frameworks/Python.framework/Versions

2.6
2.7
2.5 -> 2.6
2.3 -> 2.6
Current -> 2.7

我不确定这里可能缺少什么。如何在Mac中设置/添加python路径？请帮助我理解和克服这一点。您能在这里帮我吗？
