Question

我在virtualenv中安装gym-atari时遇到了麻烦。据我所知，看起来就像问题是zlib，但zlib安装在系统上（cmake也是如此）。有人有主意吗？这是在Gentoo系统上，因为它值得：

有什么想法吗？我唯一的猜测是，不知何故zlib没有被拉进virtualenv ???也许它甚至不是zlib？

O.k。，所以这最终是一个Gentoo问题 - 我会发布解决方案以防其他人拥有它。

按照说明here（使用atari-py而不是netifaces），我能够获得我可以编辑的软件包版本。然后我将以下内容添加到/tmp/atari-py-0.0.18/atari_py/ale_interface/src/emucore/unzip.h的顶部：

/* 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

然后运行pip install。来自/tmp/atari-py-0.0.18就可以了。

对于以后的任何人，如果选择的答案不能解决您的问题，请确保已安装cmake。 sudo apt install cmake在ubuntu / debian上。
