在virtualenv中安装Gym [atari]

Question

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）。 有人有想法么？ 这是在Gentoo系统上的，它的价值：

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？

Answer 1

好的，这最终是一个Gentoo问题-我将发布解决方案，以防其他人使用。

按照此处的说明（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。

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sudo apt install cmake 。
