為什么pip install會掛在該URL上？

Question

背景

自從我花時間編程以來已經有一段時間了，所以我決定在RaspberryPi上解決一個項目。

我正在嘗試開發一個名為aosong的模塊。 我目前在Github和Pypi上發表過它。 它有一個名為quick2wire-api的依賴項，僅在Github上托管 。

目標

最終，我的目標是在我正在構建的應用程序中進行pip install aosong或將aosong pip install aosong在requirements.txt文件中，並使其包含`quick2wire的安裝

當前狀態

因此，當我嘗試進行pip安裝時，這就是我得到的

此時，它會掛起10分鍾或更長時間。 經過一段時間后，剩下的就是這部分了：

在本地

如果我從asong模塊的根目錄安裝pip install -r requirements.txt ，則安裝可以完美進行。

此外，如果我通過安裝工具進行安裝，則ala python setup.py install也可以正常運行。

問題

有人可以幫我理解為什么pip install aosong沒有安裝quick2wire-api1依賴項嗎？

Answer 1

pip install --process-dependency-links aosong
