pip 出现问题，无法从 cmd 安装模块

Question

I just get a syntax error. I've tried these commands:

pip install opencv-python 
pip3 install opencv-python 
python -m pip install opencv-python 

All of these just give me a syntax error.

Trying to install opencv for some webcams, going to be messing with raspberry later.

Answer 1

If you are on Windows you have just to type py -m pip install opencv-python .

If you are on a Linux distribution you should firstly install python-pip or python3-pip (via your package manager) and then type:

• pip (or pip3) install opencv-python (if you want to install it locally).
• sudo pip (or pip3) install opencv-python (if you want to install it globally).
