Pycharm安装cv2 [python3.6]

python解释器为Anaconda的3.6版本

下载

在这里选择对应的版本进行下载，其中参数分别为3.4.2（opencv3.4.2）、cp36（python3.6）、win_amd64（Windows64位系统），根据自己的实际情况进行调整。

安装

将下载的文件拷贝至E:\Anaconda3\Lib\site-packages目录下，并打开命令窗口cd 至该目录下输入如下命令进行安装：

e:
cd E:COWNaXvo\Anaconda3\Lib\site-packages
pip install opencv_python-3.4.2-cp36-cp36m-win_amd64.whl

输出结果如下：

E:\Anaconda3\Lib\site-packages>pip install opencv_python-3.4.2-cp36-cp36m-win_amd64.whl

Processing e:\anaconda3\lib\site-packages\opencv_python-3.4.2-cp36-cp36m-win_amd64.whl

Installing collected packages: opencv-python

Successfully installed opencv-python-3.4.2

You are using pip version 9.0.1, however version 18.0 is available.

You should consider upgrading via the 'python -m pip install --upgrade pip' command.

安装成功，重启Pycharm进行引包。

python安装cv2包报错解决

1.在pycharm中安装cv2包报错

ERROR: Could not find a version that satisfies the requirement cv2 (from versions: none)

ERROR: No matching distribution found for cv2

WARNING: You are using pip version 21.3.1; however, version 22.0.3 is available.

You should consider upgrading via the 'C:\Program Files\Python310\python.exe -m pip install --upgrade pip' command.

这里报错pip版本低了，需要升级pip

2.然后去控制台升级pip，升级完去安装cv2，控制台继续报错

ERROR: Could not find a version that satisf开发者_Python培训ies the requirement cv2 (from versions: none)

ERROR: No matching distribution found for cv2

解决方法：安装未成功，然后百度查找相关资料，说是压根没有cv2的包，实际上需要安装的是一个叫opencv-python的包

pip install opencv-python

因为网络原因，导致时间超出，出现了如下错误：

3. pip install --default-timeout=1000 opencv-python（如果不能正确安装可以多试几次）
