pip3 install apscheduler 报错，应该如何解决？

Could not fetch URL https://pypi.python.org/simple/apscheduler/: There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:748) - skipping

Could not find a version that satisfies the requirement apscheduler (from versions: )

No matching distribution found for apscheduler

有网友提出的解决方法是 pip3 install certifi

但似乎并没有用，因为已经安装了 certifi

pip3 install certifi

Requirement already satisfied: certifi in /usr/local/lib/python3.6/site-packages

Python 版本 3.6，macos10.12

你试下换个源. `pip3 install apscheduler -i https://pypi.douban.com/`

@TimePPT 无法升级，升级也是同样的提示：Could not fetch URL https://pypi.python.org/simple/pip/: There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:748) - skipping

用 curl 访问一下试试。
猜测你机器的 ca 证书有问题。

@raysonx 的确是证书的问题。谢谢🙏
