Question

您好！ 在python3脚本中导入时无法找到pylirc。但对于python2，它的工作原理。我使用pip3来安装pylirc，因为我的Linux发行版没有python3的包pylirc。但它有python2。这是python3中的某个错误吗？你认为有解决方法吗？

> python3 -c 'import pylirc' 
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named 'pylirc'

从strace中可以看出python不会尝试在其路径中找到pylirc。这很奇怪（或者不是？）。不知何故，python正在寻找＆lt;字符串＆gt; 而不是pylirc。这里的魔力是什么？： - ）

似乎pylirc c模块与python3不兼容。因为pylirc不像这里描述的https://docs.python.org/3/howto/cporting.html那样调用PyModule_Create（）。 pylirc https://github.com/offlinehacker-playground/pylirc2/blob/master/pylircmodule.c

的代码

python3.4：虽然安装在我的系统上，但未加载pylirc模块
