我已将 Python 2.6.4 安装到预装了 Python 2.3.4 的 Linux 计算机上的主目录(子目录中),因为我需要运行一些代码,但我认为这些代码在 2.3.4 上运行需要做大量工作。(我不在该计算机的 sudoers 列表中。)
我希望我可以运行~/Python-2.6.4/python setup.py install
(从我主目录中的 PyYAML 目录,我在那里解压了 PyYAML 源),并且它会足够智能地将其安装到我本地的 Python 2.6.4 安装中。但事实并非如此。(参见 PS)
是否可以将 PyYAML 安装到我的本地 Python 安装中,以便调用该 Python 时“import yaml”可以正常工作?如果可以,我该怎么做?
PS 这是我运行时的输出~/Python-2.6.4/python setup.py install

答案1
查看setup.py 的--home
或--user
或--prefix
开关。这些控制文件的安装位置。
不过,从您的构建日志来看,我不确定这是否是问题所在。它似乎无法找到 yaml.h。它是 PyYAML 源的一部分吗?还是它是 PyYAML 需要但您忘记安装的 libyaml 的一部分?
答案2
我没有正确安装 Python。当我按照克拉斯特的指示https://stackoverflow.com/questions/2278028/how-do-i-work-around-this-problem-creating-a-virtualenv-environment-with-a-custom/2278059#2278059之后我就可以毫无问题地安装 PyYAML 了。(不需要 virtualenv。)
