Question

我正在尝试通过pip3安装软件包

pip3 install keras

但是，错误如下：

Collecting keras
Exception:

我的研究所需要代理，并且我使用ProxyMan在系统中的所有位置更新了代理。

是由于代理吗？因为我重新安装了Linux。如果由于代理原因，我需要在哪里更新代理？

Answer 1

我有一个类似的问题，我通过在/etc/bash.bashrc的末尾添加代理设置来解决该问题，如下所示：

export http_proxy="http://<user>:<pass>@<proxy>:<port>
export https_proxy="https://<user>:<pass>@<proxy>:<port>
export ftp_proxy="ftp://<user>:<pass>@<proxy>:<port>
export socks_proxy="socks://<user>:<pass>@<proxy>:<port>

Answer 2

您可以尝试使用easy_install + packagename代替pip。
