python - 导入错误:无法导入名称 'certs'

Question

过去 2 天我遇到了此错误。这似乎是 python requests 库的问题，但我已经重新安装了好几次了，但没有成功。

Traceback (most recent call last):

    from . import certs

    ImportError: cannot import name 'certs'

可能是两天前 Windows 7 更新的问题，因为这是最近几天唯一发生变化的事情。

顺便说一下，我使用的是带有 virtualenv 的 python 3.4、PyCharm 3.4.1 IDE 和 Win7。

在 certs.py 中存在有问题的代码(最后一行):

try:
    from certifi import where
except ImportError:
    def where():
        """Return the preferred certificate bundle."""
        # vendored bundle inside Requests
        return os.path.join(os.path.dirname(__file__), 'cacert.pem')

这对我有用(重新安装请求库):


pip 卸载请求
pip 安装请求
