pip安装第三方库moviepy报错SSL: CERTIFICATE_VERIFY_FAILED

 请勿走弯路。快速判断

1、PIP10以后的版本早就修复该问题，如果自己的版本过低

可以通过设置pypi.org和files.pythonhosted.org作为可信赖的主机。

2、优先检查自己的网络，是否开抓包，是否设置代理

以下是我走的弯路，虽然很快发现，才恍然大悟，希望汲取教训。特别是做测试的同学，经常喜欢开代理或者是抓包工具。

pip install moviepy==1.0.2

Could not fetch URL https://pypi.org/simple/moviepy/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/moviepy/ (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1045)'))) - skipping

当报错这个第一反应，请求https确实证书，不信任。

加信任就好:pip --trusted-host pypi.python.org install moviepy

 pip --trusted-host pypi.python.org install moviepy  

Could not fetch URL https://pypi.org/simple/moviepy/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/moviepy/ (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1045)'))) - skipping
ERROR: Could not find a version that satisfies the requirement moviepy (from versions: none)
ERROR: No matching distribution found for moviepy

接着信任  pip  install --trusted-host pypi.org  --trusted-host files.pythonhosted.org moviepy

pip  install --trusted-host pypi.org  --trusted-host files.pythonhosted.org moviepy

ERROR: Could not install packages due to an EnvironmentError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Max retries exceeded with url: /packages/71/64/e7f0876716d5c35612bf8e9e49299d0f491285f10f36cbb481556ab0062b/moviepy-1.0.2.tar.gz (Caused by ReadTimeoutError("HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Read timed out. (read timeout=15)"))

这个时候应该醒悟，如果是证书错误，这个域名下的，早就不能安装了，由于刚刚新笔记本不应该有类似问题。

排查网络发现自己开了代理。
