我有一个 docker 镜像,我需要在其中安装 openCV,从昨天开始它开始失败,因为它找不到“skbuild”模块:

在主机上我也找不到那个模块和

要么不返回任何内容,要么返回服务器错误:

这是因为他们的服务器有问题还是与我的 pip 有关?
pip install scikit-build
在 opencv 安装之前的一步,但我得到另一个与 cmake 相关的错误:

最佳答案
如果您阅读 opencv-python
package FAQ in PyPI ,它清楚地为这个特定问题提供了答案:您必须运行 pip install --upgrade pip
.查看 pip
之后的版本 pip -V
.
这是因为您的 pip
太老了,看不懂新的manylinux2014
包格式并尝试从源代码编译。这也将失败,因为 pip
太老了,不懂怎么用pyproject.toml
安装构建依赖项,例如 scikit-build
.
我发现的另一个问题是您同时安装了 opencv-python
和 opencv-contrib-python
.你不应该这样做。它也在包的 PyPI 页面中进行了解释。您很可能应该只使用 opencv-contrib-python-headless
包,因为您使用的是 Docker,并且我假设您不使用 OpenCV 的 GUI 功能。
