导入错误ghmm库

Question

我收到此错误:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.6/dist-packages/ghmm.py", line 112, in <module>
    import ghmmwrapper
  File "/usr/local/lib/python2.6/dist-packages/ghmmwrapper.py", line 25, in <module>
    _ghmmwrapper = swig_import_helper()
  File "/usr/local/lib/python2.6/dist-packages/ghmmwrapper.py", line 21, in swig_import_helper
    _mod = imp.load_module('_ghmmwrapper', fp, pathname, description)
ImportError: libghmm.so.1: cannot open shared object file: No such file or directory

但

root@ubuntu:~# sudo locate libghmm
/usr/local/lib/libghmm.a
/usr/local/lib/libghmm.la
/usr/local/lib/libghmm.so
/usr/local/lib/libghmm.so.1
/usr/local/lib/libghmm.so.1.0.0

为什么我会收到此错误？我尝试添加

/usr/local/lib/

我的PYTHONPATH

但它不起作用.

Answer 1

PYTHONPATH 正在为python模块工作,而不是为系统库工作.

您可以将本地路径添加到系统:

1. 以root身份编辑 /etc/ld.so.conf
2. 添加新行 /usr/local/lib
3. 保存并退出
4. 运行"sudo ldconfig"

然后重启你的应用程序,它会工作.

如果您不想对系统进行任何更改,可以使用环境变量:

LD_PRELOAD_PATH=/usr/local/lib python <yourapp.py>
