无法通过 pip 安装 Scipy [英] Can't install Scipy through pip

问题描述

通过 pip 安装 scipy 时:

When installing scipy through pip with :

pip install scipy

Pip 构建 scipy 失败并抛出以下错误:

Pip fails to build scipy and throws the following error:

Cleaning up...
Command /Users/administrator/dev/KaggleAux/env/bin/python2.7 -c "import setuptools, tokenize;__file__='/Users/administrator/dev/KaggleAux/env/build/scipy/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /var/folders/zl/7698ng4d4nxd49q1845jd9340000gn/T/pip-eO8gua-record/install-record.txt --single-version-externally-managed --compile --install-headers /Users/administrator/dev/KaggleAux/env/bin/../include/site/python2.7 failed with error code 1 in /Users/administrator/dev/KaggleAux/env/build/scipy
Storing debug log for failure in /Users/administrator/.pip/pip.log

如何让 scipy 成功构建?这可能是 OSX Yosemite 的一个新问题，因为我刚刚升级并且之前安装 scipy 没有遇到问题.

How can I get scipy to build successfully? This may be a new issue with OSX Yosemite since I just upgraded and haven't had issues installing scipy before.

推荐答案

在打开一个问题之后SciPy 团队，我们发现您需要升级 pip:

After opening up an issue with the SciPy team, we found that you need to upgrade pip with:

pip install --upgrade pip

在 Python 3 中，这是有效的:

And in Python 3 this works:

python3 -m pip install --upgrade pip

为了正确安装 SciPy.为什么?因为:

for SciPy to install properly. Why? Because:

必须告诉旧版本的 pip 使用轮子，IIRC 和 --use-wheel.或者您可以升级 pip 本身，然后它应该会重新启动.

Older versions of pip have to be told to use wheels, IIRC with --use-wheel. Or you can upgrade pip itself, then it should pick up the wheels.

升级 pip 解决了这个问题，但您也可以只使用 --use-wheel 标志.

Upgrading pip solves the issue, but you might be able to just use the --use-wheel flag as well.
