這篇文章主要介紹了Pycharm之如何安裝cv2 [python3.6]問題，具有很好的參考價值，希望對大家有所幫助。如有錯誤或未考慮完全的地方，望不吝賜教

Pycharm安裝cv2 [python3.6]

python解釋器為Anaconda的3.6版本

下載

這里寫圖片描述

在這里選擇對應(yīng)的版本進行下載，其中參數(shù)分別為3.4.2（opencv3.4.2）、cp36（python3.6）、win_amd64（windows64位系統(tǒng)），根據(jù)自己的實際情況進行調(diào)整。

安裝

將下載的文件拷貝至E:\Anaconda3\Lib\site-packages目錄下，并打開命令窗口cd 至該目錄下輸入如下命令進行安裝：

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

輸出結(jié)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.

安裝成功，重啟Pycharm進行引包。

python安裝cv2包報錯解決

1.在pycharm中安裝cv2包報錯

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.

這里報錯pip版本低了，需要升級pip

2.然后去控制臺升級pip，升級完去安裝cv2，控制臺繼續(xù)報錯

ERROR: Could not find a version that satisfies the requirement cv2 (from versions: none)
ERROR: No matching distribution found for cv2

解決方法：安裝未成功，然后百度查找相關(guān)資料，說是壓根沒有cv2的包，實際上需要安裝的是一個叫opencv-python的包

pip install opencv-python

因為網(wǎng)絡(luò)原因，導(dǎo)致時間超出，出現(xiàn)了如下錯誤：
