我在 Windows 10 版本 2004 x64 上使用 Python 3.9。以管理员身份使用 PowerShell。

蟒蛇版：

Python 3.9.0 (tags/v3.9.0:9cf6752, Oct  5 2020, 15:34:40) [MSC v.1927 64 bit (AMD64)] on win32

安装matplotlib错误。

pip install virtualenv
virtualenv foo
cd .\foo
.\Scripts\active
pip install numpy
pip install matplotlib

错误

当我使用brew安装OpenCV时,每当我运行此命令进行测试时,我都会遇到此问题 brew

RuntimeError: module compiled against API version 9 but this version of numpy is 6
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: numpy.core.multiarray failed to import

我试图升级numpy,但这很令人困惑

>>> import numpy
>>> print numpy.__version__
1.6.1

当我运行brew来升级numpy时,我遇到了这个问题.

brew install -u numpy
Warning: numpy-1.9.1 already installed

当我卸载它

sudo pip install numpy
Requirement already satisfied (use --upgrade to upgrade): numpy in ./anaconda/lib/python2.7/site-packages

我已经关注了这个帖子并从我的mac中删除了anaconda.

pip install numpy
Requirement already satisfied (use --upgrade to upgrade): numpy in /Library/Python/2.7/site-packages …

尝试使用以下方法解决它：

pip install -U numpy

但它仍然不起作用。

这是我尝试运行该应用程序时控制台向我显示的内容：

    RuntimeError: module compiled against API version 0xa but this version of numpy is 0x9
