我一直在尝试安装Python库lxml，但这里是输出。过去半小时我一直在研究依赖关系，但我认为这不是问题所在。
我在CentOS 6上运行此脚本，512 MB RAM。它是来自Digital Ocean的全新服务器，它几乎没有任何运行。
下面的完整错误日志。
# sudo pip install lxml
DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of pip will drop support for Python 2.6

答案 0 :(得分：1)
基本上，汇编错误是因为gcc的程序集输出在被杀死时被中断了。 Gentoo论坛帖子暗示这可能是因为gcc耗尽了太多内存。您可以通过检查dmesg输出结尾附近的OOM内容来确认这一点。如果内存不是问题，那么您可能有一个真正的错误，应该按照您粘贴的文本中的说明将错误报告给https://bugs.gentoo.org/。但是，请先尝试查看内存是否是问题。
如果内存是问题，请确保您的计算机上有交换分区并且已启用它们。您可以通过运行swapon -s来查看已启用的交换分区的摘要。如果没有显示任何内容且您无法重新分区，您可以随时使用
这样的技巧# ( umask 0077 && \
dd if=/dev/zero of=/.swap.img bs=1M count=1024 && \
mkswap /.swap.img && \
swapon /.swap.img )
（'＃'表示根shell提示符，因此实际上不要键入它）。论坛帖子还建议删除-pipe，这会导致gcc使用更多内存而不是写出大量临时文件，来自CFLAGS和CXXFLAGS（通过编辑/etc/make.conf或/etc/portage/make.conf，无论哪个存在）。我们无法从您发布的内容中了解您的CFLAGS。
