Could not fetch URL https://pypi.python.org/simple/opencv-python/: There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:661) - skipping

證書問題

1. 升級 pip

• pip 本身都要問題，故 pip install pip 不可用
• 手動安裝

steps:

1. https://pypi.org/project/pip/

2. 解壓

tar -zxvf

3. python setup.py install

4. success

2. 跳過 ssl 校驗

使用一下命令安裝

pip --trusted-host pypi.python.org install <包名>
