python - 无法在我的 Raspberry Pi 上使用 pip 安装 Flask

Question

我正在尝试在我的 Raspberry Pi 上安装 Flask，但似乎无法使用以下命令:sudo pip install flask。我总是回复这条消息:

Downloading/unpacking flask
Cleaning up...
Exception:

    req, link, "connection error: %s" % exc, url,

Storing debug log for failure in /root/.pip/pip.log

有人知道出了什么问题吗？
