【问题描述】：

在我的 centos 服务器上，每当尝试安装新软件包时，我突然收到 SSL 验证失败消息。

有人可以帮我解决这个问题吗？

在新机器上：

easy_install-2.7 pip Searching for pip Reading https://pypi.python.org/simple/pip/ Best match: pip 10.0.1 Downloading https://files.pythonhosted.org/packages/ae/e8/2340d46ecadb1692a1e455f13f75e596d4eab3d11a57446f08259dee8f02/pip-10.0.1.tar.gz#sha256=f2bd08e0cd1b06e10218feaf6fef299f473ba706582eb3bd9d52203fdbd7ee68 error: Download error for https://files.pythonhosted.org/packages/ae/e8/2340d46ecadb1692a1e455f13f75e596d4eab3d11a57446f08259dee8f02/pip-10.0.1.tar.gz#sha256=f2bd08e0cd1b06e10218feaf6fef299f473ba706582eb3bd9d52203fdbd7ee68: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:579)

我之前使用 pip 安装了许多 python 模块的现有服务器，但现在我收到 ssl 验证错误

【参考方案1】：

此错误是由尚未排序的https://github.com/pypa/setuptools/issues/1543 引起的。

我知道的唯一解决方法是避免使用代理，或者至少使用不会重写 SSL 证书的代理。
