安裝py3cairo for Python 3.6

Question

我想要安裝pygobject，但其中一個依賴項是py3cairo。我已經安裝它用於Python 3.4，但現在我想用Python 3.6來使用它。

我知道我可以sudo apt-get install python3-cairo安裝它，但它說，它已經安裝：

$ sudo apt-get install python3-cairo

Building dependency tree

python3-cairo is already the newest version. 
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded. 

然而，

試圖建立/安裝從源代碼是醜陋的，因爲我得到全部種問題：

如何獲得py3cairo並解決這些問題？

Answer 1

我想在slackware 14.2上做同樣的事情，用python3.6編譯pycairo。我得到和你一樣的錯誤， ，也沒有提到的各種waf補丁。

我在這方面做了一個進步。 slackware-current發行版似乎運行了一個waf腳本。它位於http://ftp.slackware.com/pub/slackware/slackware-current/source/l/pycairo/

您提到的上述錯誤在此腳本中丟失，但是當它嘗試編譯cairomodule.c中的錯誤時會彈出另一個錯誤。

slackware-current構建幾乎使它，但仍然失敗，編譯錯誤。也許有更多經驗的人可以解決它。
