IPython sys.path与python sys.path不同

Question

我通常使用IPython,并且最近才注意到常规python shell中导入的搜索路径是错误的.根据我的理解,sys.path继承自PYTHONPATH(虽然我不知道PYTHONPATH住在哪里),这在IPython中是不同的？我担心这个有影响的装置.比如我刚尝试过

pip install --upgrade gensim

失败,因为它无法解决我已经安装的scipy依赖项.所以我在Ipython中找到了更深入的鸽子

import gensim
gensim.__version__

在python中返回.9.1

import gensim
gensim.__version__

返回.8.9

以下是Ipython版本的sys.path的样子:

['',
    '/Users/change/anaconda/bin',
    '/Users/change/anaconda/lib/python2.7/site-packages/pybing-0.12-py2.7.egg',
    '/Users/change/anaconda/lib/python2.7/site-packages/httplib2-0.8-py2.7.egg',
    '/Users/change/anaconda/python.app/Contents/lib/python27.zip',

    '/Users/change/anaconda/lib/python2.7/site-packages/IPython/extensions']

和常规的python脚本sys.path:

现在对您来说可能为时已晚，但这里的答案也可能对您有帮助：ipython 读取错误的 python 版本。基本上，ipython 脚本可以直接引用特定的 python 二进制文件，而不是直接运行 python 时获得的二进制文件。
