获取SSLError证书验证失败

标签： python macos pip ssl-certificate

好像我的某些系统设置搞砸了。我在MAC OS上，使用浏览器转到任何https站点或卷曲到失败站点以下都没有问题 我在下面的3行代码中收到了SSLError（以下错误）

MaxRetryError: HTTPSConnectionPool(host='maps.googleapis.com', port=443): Max retries exceeded with url: /maps/api/geocode/json?address=denver&key=AIxxxxxxxxx (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1045)')))

我已经在python2.7.10和python3.7.0上都尝试过

出现错误的代码：

我是新来的，所以请不要苛刻，这可能很简单，这就是为什么我最近4个小时一直在网上搜索，似乎your server is not sending a TLS cert chain可能是一个原因，但我不知道实际原因或解决方法

对于其他升级pyopenssl的人，此问题已解决（我的pyopenssl最新版本为19.0.0），大多数人使用请求并使用verify = False进行修复 另外，如果还有其他方法可以测试其他电话是否正常工作，请告诉我

以前我也通过pip install收到SSLError，但是通过将pip升级到最新版本并将受信任的主机添加到pip.conf来解决此问题

我找不到与“解决方案”类似的问题，上一个已经关闭，但仅针对特定站点： https://github.com/kennethreitz/requests/issues/4381 https://github.com/kennethreitz/requests/issues/4247 Python Requests getting SSLerror

=================== ///基于评论进行更新：

几个搜索结果表明，解决方法是运行/Applications/Python\ 3.6/Install\ Certificates.command 我当时在3.7.0上，但是/Applications/Python\ 3.7/Install\ Certificates.command不存在 我无法确定正确的“安装证书”命令，因此我升级到3.7.3，并且安装过程中没有任何Install Certificate命令，因此最终我降级到3.6.0并运行上述命令 

$ python3 --version

我不确定pip3和pip是否不同，但是无论我尝试了$ pip3 install googlemaps是因为我看到pip list中都存在googlemaps，而pip3 list中却没有

当我的ipython打开该版本时，看起来我仍然拥有python 3.7.3：

$ ipython

很抱歉，如果这个时间太长，但看起来好像我缺少什么，我已经花了16个小时以上，仍然停留在同一问题上。
