我在virtualenv中安装Gym-atari时遇到问题。据我所知，问题似乎出在zlib上，但zlib已安装在系统上(cmake也是如此)。谁有想法？这是在Gentoo系统上的，它的值(value):

有任何想法吗？我唯一的猜测是zlib不会以某种方式进入virtualenv？也许甚至不是zlib？
最佳答案
好吧，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。
按照here的说明(使用atari-py而不是netifaces)，我可以获得可以编辑的软件包的版本。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的技巧。
