?如何pip安裝cairocffi?
cairocffi
是基於CFFI的嵌入式替代品Pycairo
https://github.com/SimonSapin/cairocffi。
我試圖在Ubuntu 14.04安裝:

我手動檢查許可,我意識到沒有寫訪問權限。 這是爲什麼?爲什麼sudo不能覆蓋權限呢?

由於@MattDMo的建議,我已經試過apt-get install libffi
但它仍然沒有解決:
[email protected]:~$ sudo apt-get install libffi libffi-dev

E: Unable to locate package libffi
但包管理器上沒有任何libffi
,所以我試過libffi-dev

正如我所說的,你需要使用你的Linux發行包管理器('yum','apt-get',無論)來安裝系統包'libffi'和'libffi-dev'。對不起,如果不是很清楚。 – MattDMo
