OpenCV Python PIP安装损坏?

Question

win10 x64 Python 3.6

我试图将最新版本的opencv-contrib-python从PyPi安装到conda环境中。我昨天做这件事没有问题，但今天它坏了。

在我激活的环境中，从conda命令行(作为Admin)，我尝试了

pip install opencv-contrib-python
pip install opencv-contrib-python --user
pip install opencv-python
pip install opencv-python --user

都抛出相同的页面&满页的错误。一些highights,

ERROR: Command errored out with exit status 1:

确实有好几页。大部分看起来像CMake生成的输出，搜索&找到东西，但我从来没有见过类似的任何其他OpenCV安装之前。

我已经更新了pip和setup-tools，仍然是相同的错误。我已经尝试了所有的修复，我可以在这里找到，仍然是相同的错误。我试过直接从克隆的git仓库安装，仍然是相同的错误

有人见过这种行为吗?

Answer 1

您可能需要运行

pip install --upgrade wheel

在

pip install opencv-contrib-python

自从你更新了pip和setup-tools之后，这是我唯一能想到更新的东西。
