python - 无法启动主管守护进程

Question

重新启动 supervisord 时出现以下错误。我搜索了它并尝试了 pip install --upgrade setuptools 和 easy_install --upgrade pip 但没有任何效果。

$ sudo /etc/init.d/supervisord start
Starting supervisord: Traceback (most recent call last):
  File "/usr/local/bin/supervisord", line 6, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python2.6/dist-packages/pkg_resources/__init__.py", line 3020, in <module>
    working_set = WorkingSet._build_master()
  File "/usr/lib/python2.6/dist-packages/pkg_resources/__init__.py", line 616, in _build_master
    return cls._build_from_requirements(__requires__)
  File "/usr/lib/python2.6/dist-packages/pkg_resources/__init__.py", line 629, in _build_from_requirements
    dists = ws.resolve(reqs, Environment())
  File "/usr/lib/python2.6/dist-packages/pkg_resources/__init__.py", line 807, in resolve
    raise DistributionNotFound(req)

                                                           [FAILED]

我正在使用 Amazon AMI 实例。请帮忙。

Answer 1

我使用 Amazon Linux AMI 启动了一个新的 Amazon EC2 实例并做了:

sudo easy_install supervisor

它运行良好。
