Question

在pycharm上无法下载numpy软件包，在终端上运行以下命令：pip install --index-url http://pypi.tuna.tsinghua.edu.cn/simple/ numpy，依然无法下载且出现以下内容：
C:\Users\13305>pip install --index-url http://pypi.tuna.tsinghua.edu.cn/simple/ numpy
Looking in indexes: http://pypi.tuna.tsinghua.edu.cn/simple/

翻译如下：
警告：存储库位于pypi.tuna.tsinghua.edu。cn不是受信任或安全的主机，正在被忽略。如果此存储库可通过HTTPS访问，我们建议您改用HTTPS，否则您可以取消此警告，并允许使用“--trusted host pypi.tuna.tsinghua.edu.cn”。
错误：找不到满足要求audio2numpy的版本（来自版本：无）

你的命令没有使用国内镜像源后出现超时错误，你试试下面这个命令。
pip install numpy -i https://pypi.tuna.tsinghua.edu.cn/simple
或者pip install numpy -i https://pypi.mirrors.ustc.edu.cn/simple
pip install numpy -i http://pypi.douban.com/simple/

你先试试，如果还是不行，发下问题图片。
