无法安装OpenCV python3.8
无法安装OpenCV python3.8
提问于 2020-08-14 09:56:20
当我执行这个命令时：
pip3 install opencv-python
我得到以下错误：

尝试升级您的pip
pip install --upgrade pip然后运行
pip install opencv-pythonStack Overflow用户

pypi网站上的安装和使用指南如下
Pip安装在ModuleNotFoundError中失败:没有名为“skbuild”的模块？
自从OpenCV-python4.3.0.*版本以来，manylinux1车轮被manylinux2014车轮所取代。如果您的pip太旧，它将尝试使用4.3.0.38中引入的新源代码发行版手动构建OpenCV，因为它不知道如何安装manylinux2014轮毂。但是，由于pip太老，源代码构建也将失败，因为它不理解pyproject.toml中的构建依赖关系。要使用新的manylinux2014预置车轮(或从源代码构建)，您的pip版本必须是>= 19.3。
请用
pip install --upgrade pip

我也面临着类似的情况：
Dockerfile：
FROM nvidia/cuda:10.0-cudnn7-runtime-ubuntu18.04
RUN apt-get update -y
RUN apt-get install -y vim curl iputils-ping python3-dev python3-pip libsm6
libxext6 libxrender-dev python3.6
RUN pip3 install -r /requirements.txt
...requirements.txt：
...
opencv-python
...在运行docker-compose up &时，我收到了以下错误：
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/tmp/pip-build-acog3xol/opencv-python/setup.py", line 9, in <module>
import skbuild
ModuleNotFoundError: No module named 'skbuild'我尝试了升级pip3的建议解决方案，但遇到了同样的问题。
对我起作用的是修复requirements.txt中的requirements.txt版本。在此之前，它使用的是4.4.0.40版本。我将requirements.txt改为：
...
opencv-python==4.2.0.34
