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，看起来 问题出在 zlib，但系统上安装了 zlib（cmake 也是如此）。谁有想法？这是在 Gentoo 系统上，它的价值：

有什么想法吗？我唯一的猜测是 zlib 没有以某种方式被拉入 virtualenv？？？也许它甚至不是 zlib？

Answer 1

O.k。所以这最终是一个 Gentoo 问题——我会 post 解决方案以防其他人有它。

按照说明 here（使用 atari-py 而不是 netifaces），我获得了一个可以编辑的包版本。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

然后运行点安装。来自 /tmp/atari-py-0.0.18 成功了。

对于将来的任何人，如果选择的答案不能解决您的问题，请确保您已安装 cmake。 sudo apt install cmake 在 ubuntu/debian。
