在Mac OS X中安装IPython:
使用sudo pip install ipython指令安装ipython,运行结果出现
主要错误为:
raise VersionConflict(dist,req) # XXX put more info here
pkg_resources.VersionConflict: (certifi 2016.2.28 (/Library/Python/2.7/site-packages), Requirement.parse(‘certifi==2015.11.20’))
为此楼主用尽了各种办法,比如
结果都不work啊,抓狂中。。。
偶然发现了两个方法可有效解决此问题,可把楼主兴奋的~~~现贴出来与大家共享
方法一:
所有的问题出在
所以可以从https://pypi.python.org/pypi/certifi 中下载,然后install from source
运行这句命令
或者可以直接卸载certifi 2016.2.28
然后安装符合要求的certifi==2015.11.20。
为避免产生
再更新distribute
方法二:
创建虚拟环境运行ipython
这时便已经进入了虚拟环境,现在便可使用
当你想退出这个虚拟环境时,使用命令
python -V Python 2.7.6 pip -V pip 8.1.1 from /Library/Python/2.7/site-packages (python 2.7)
使用sudo pip install ipython指令安装ipython,运行结果出现

为此楼主用尽了各种办法,比如
sudo pip install --upgrade setuptools
sudo pip install ipython --allow-all-external
结果都不work啊,抓狂中。。。
偶然发现了两个方法可有效解决此问题,可把楼主兴奋的~~~现贴出来与大家共享
方法一:
所有的问题出在
certifiversion conflict
所以可以从https://pypi.python.org/pypi/certifi 中下载,然后install from source
运行这句命令
sudo python setup.py install便可顺利解决此问题。
或者可以直接卸载certifi 2016.2.28
sudo pip uninstall certifi
然后安装符合要求的certifi==2015.11.20。
sudo pip install certifi==2015.11.20
为避免产生
RuntimeError: maximum recursion depth exceeded的错误
再更新distribute
pip install --upgrade distribute
方法二:
创建虚拟环境运行ipython
>>>pip install virtualenv >>>virtualenv venv >>>source venv/bin/activate
这时便已经进入了虚拟环境,现在便可使用
pip install ipython安装。
当你想退出这个虚拟环境时,使用命令
>>>deactivate
