ERROR:无法为opencv-python构建轮子，该轮子使用PEP 517，不能直接安装。

我试图将OpenCV4安装在jetson nano的docker中。它有jetpack 4.4 s os。docker已经成功创建，Tensorflow也在运行，但在使用pip安装OpenCV时，却显示CMake错误。

           我有同样的问题，我这样做了。
          
          pip install --upgrade pip setuptools wheel
然后再次安装opencv。
pip install opencv-python
this worked for me

              这个答案，应该放在上面。在顶部!在Windows上立即解决了这个问题。


           
            
             
              ERROR。由于EnvironmentError，无法安装软件包。


           
            
             
              即使按照这个方法，这个错误在Mac Sierra上仍然会弹出。

            pip install --upgrade pip setuptools wheel
你仍然有同样的错误。
你可以尝试指定安装旧版本的OpenCV。
pip3 install opencv-python==3.4.13.47

               是的......终于找到了一个解决方法。
按照这个方法
               
                https://github.com/mdegans/nano_build_opencv
               
               并从源代码构建，最后得到安装。
              
              
               PS: 它可能要花一点时间来建造，对我来说，它花了10个小时:P。

                你好，谢谢你的分享。我也遇到了同样的错误，昨天晚上用参数--platform linux/arm/v7的numpy构建，花了11个小时，还是没有完成。


          
           
            
             
              
               我也遇到过类似的问题，解决它的方法是不使用
               
                python:3-alpine
               
               而使用
               
                python:3.8-slim
               
               。例如。
              
              FROM python:3.8-slim
WORKDIR /usr/src/app
RUN apt update
RUN apt -y install build-essential libwrap0-dev libssl-dev libc-ares-dev uuid-dev xsltproc
RUN apt-get update -qq \
    && apt-get install --no-install-recommends --yes \
        build-essential \
        gcc \
        python3-dev \
        mosquitto \
        mosquitto-clients
RUN pip3 install --upgrade pip setuptools wheel
RUN python3 -m pip install --no-cache-dir \
      numpy scipy matplotlib scikit-build opencv-contrib-python-headless \
      influxdb paho-mqtt configparser Pillow \
      qrcode
对我来说，终于起作用了。


          
           
            
             
              
               
                请检查你的Python规格。
               
               - opencv -> python[
version='
>=2.7,<2.8.0a0
>=3.5,<3.6.0a0

                我通过在我的MacBook上从头开始重新安装python3来处理这个问题。
               
               brew reinstall python@3.9
我还实验性地重新安装了numpy和matplotlib软件包。
pip3 install numpy
pip3 install matplotlib 
pip3 install opencv-contrib-python
The versions:
macOS Mojave 10.14.5

Python 3.9.7

OpenCV 4.5.3
OpenCV's version is 4.5.3 这么说来:
import cv2 
print(cv2.__version__)
But by "pip list", it shows "opencv-contrib-python 3.4.9.31".
