python - 我在尝试安装 spaCy 英语语言模型时收到 CERTIFICATE_VERIFY_FAILED

Question

我通过 Anaconda 在 Python 3.5.2 上运行 OS X El Capitan，并且有 spaCy 0.101.0。

我正在尝试使用 python -m spacy.en.download 安装 spaCy 英语语言模型.但是，当我这样做时，我收到一条错误消息 urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:645)> .完整的Traceback如下:
