I used command pip list :

package    version

pip        10.0.1

setuptools 39.0.1

Could not fetch URL https://pypi.org/simple/pip/: There was a problem        confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:841)'),)) - skipping

删除了 python3.6.6 并安装了 python3.4.4，现在命令 pip install numpy 显示错误：

找不到满足 numpy 要求的版本（来自版本：）没有找到 numpy 的匹配分布

使用此命令而不是“pip install numpy”。这最终为我工作。

pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org numpy
