python - 执行 exabgp 命令时出现 ImportError

Question

我目前正在使用 Centos 7 和 Python 2.7.5。我安装了 exabgp 4.0 和 python2-exabgp rpms。但是一旦我执行 exabgp 命令，我就会得到 ImportError：

    [root@~]# exabgp -version
    Traceback (most recent call last):
    File "/sbin/exabgp", line 9, in <module>
    load_entry_point('exabgp==4.0.1', 'console_scripts', 'exabgp')()
    File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 378, in load_entry_point
         return get_distribution(dist).load_entry_point(group, name)
    File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 2566, in load_entry_point
         return ep.load()
    File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 2260, in load
         entry = __import__(self.module_name, globals(),globals(),     ['__name__'])
    ImportError: No module named exabgp.application
