在virtualenv中安裝gym [atari]

我在virtualenv中安裝gym-atari時遇到問題。從我可以告訴，它看起來像問題是與zlib，但zlib安裝在系統上（所以是cmake）。有人有主意嗎？這是在Gentoo系統上，它的價值：在virtualenv中安裝gym [atari]

任何想法？我唯一的猜測是，不知何故zlib沒有被拉進virtualenv？也許它甚至不是zlib？

問這個問題響了，我有一個類似的問題試圖在我的Gentoo盒子上安裝ALE。解決辦法是修改unzip.h，但我不知道該怎麼做。我會打開一個新的線程，並嘗試從這裏鏈接到它。 – user3054726

也可以，所以這最終是一個Gentoo問題 - 我會發布解決方案，以防其他人擁有它。

按照說明here（使用atari-py而不是netifaces）我能夠得到我可以編輯的軟件包的一個版本。然後添加以下到/tmp/atari-py-0.0.18/atari_py/ale_interface/src/emucore/unzip.h的頂部：

/* Gentoo removed OF from their copy of zconf.h  (https://bugs.gentoo.org/show_bug.cgi?id=383179) */ 
/* but our copy of minizip needs it. */ 
#ifndef OF 
#define OF(args) args 
#endif

然後運行點子安裝。從/tmp/atari-py-0.0.18取得了訣竅。

謝謝，這也適用於我。我從github克隆了atari-py，按照你的建議更改了代碼並做了「點安裝」。像我的gentoo上的魅力一樣工作 – coolbootgeek
