我意识到我有一个过时的numpy版本：
$python Python 2.7.10 (default,Oct 23 2015,18:05:06) [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. >>> import numpy as np >>> np.version.full_version '1.8.0rc1'
我试图更新它,但由于某些原因我无法安装在整台机器上：
$sudo pip install -U numpy

好的,我只需安装到–user然后：
$pip install -U --user numpy ... Successfully installed numpy
但版本没有更新！
$python Python 2.7.10 (default,"credits" or "license" for more information. >>> import numpy as np >>> np.version.full_version '1.8.0rc1'
安装版本在哪里？
解决方法
根据
the Python docs,这是使用“用户方案”安装：
Files will be installed into subdirectories of 07001 (written as userbase hereafter).
您可以看到这样的USER_BASE值：
$python -c "import site; print(site.USER_BASE)" /Users/csaftoiu/Library/Python/2.7
我发现在我的机器上,这是在sys.path上,但是它出现在全局安装目录之后.
我通过将它添加到我的〜/ .bash_profile来解决它：
# add user base to python path export PYTHONPATH=$(python -c "import site,os; print(os.path.join(site.USER_BASE,'lib','python','site-packages'))"):$PYTHONPATH
现在确实加载了最新版本：
$python Python 2.7.10 (default,"credits" or "license" for more information. >>> import numpy >>> numpy <module 'numpy' from '/Users/csaftoiu/Library/Python/2.7/lib/python/site-packages/numpy/__init__.pyc'> >>> numpy.version.full_version '1.11.1' >>>
