首先，嘗試用pip進行安裝
(base) D:\Anaconda3\Lib>pip install opencv-python -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com
Looking in indexes: http://pypi.douban.com/simple/

Could not find a version that satisfies the requirement numpy==1.13.3 (from versions: )
No matching distribution found for numpy==1.13.3
You are using pip version 10.0.1, however version 21.2.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
就算用豆瓣源，也還總是報錯，報錯原因大概是numpy版本不符合？？？
接著我將（base）環境中的numpy重裝了，仍然沒有解決
此時，打開官網/清華鏡像，去尋找opencv-python的python38版本
顯然，選擇最下面一個進行下載
下載結束后將檔案放在 .\Anaconda3\Scripts 里邊
然后打開cmd，輸入activate進入（base）環境，用pip進行安裝
pip install "D:\Anaconda3\Scripts\opencv_python-4.5.3-cp38-cp38-win_amd64.whl"
此時 報錯
Requirement 'D:\\Anaconda3\\Scripts\\opencv_python-4.5.3-cp38-cp38-win_amd64.whl' looks like a filename, but the file does not exist
opencv_python-4.5.3-cp38-cp38-win_amd64.whl is not a supported wheel on this platform.
參考
https://www.cnblogs.com/ruoli-s/p/14204897.html
打開python后 輸入
>>> import pip._internal
>>> print(pip._internal.pep425tags.get_supported())
[('cp38', 'cp38m', 'win_amd64'), ('cp38', 'none', 'win_amd64'), ('py3', 'none', 'win_amd64'), ('cp38', 'none', 'any'), ('cp3', 'none', 'any'), ('py38', 'none', 'any'), ('py3', 'none', 'any'), ('py37', 'none', 'any'), ('py36', 'none', 'any'), ('py35', 'none', 'any'), ('py34', 'none', 'any'), ('py33', 'none', 'any'), ('py32', 'none', 'any'), ('py31', 'none', 'any'), ('py30', 'none', 'any')]
可以看到，我們的檔案名"cp38-cp38-win_amd64"并不能識別，故改為"cp38-cp38m-win_amd64"
再次執行
pip install "D:\Anaconda3\Scripts\opencv_python-4.5.3-cp38-cp38m-win_amd64.whl"
我終于看到了
