新开了一台vps，CentOS6.5系统，用pip安装了supervisor，不能运行，看提示缺少了某个模块。

记录一下过程：

错误1：

Traceback (most recent call last):
  File "/usr/bin/supervisorctl", line 5, in 
    from pkg_resources import load_entry_point
  File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 2655, in 
    working_set.require(__requires__)
  File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 648, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 546, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: meld3>=0.6.5

解决方法：

wget --no-check-certificate  https://pypi.python.org/packages/source/d/distribute/distribute-0.7.3.zip
unzip distribute-0.7.3.zip
cd distribute-0.7.3
python setup.py install

错误2：

Traceback (most recent call last):
  File "/usr/bin/supervisorctl", line 5, in 
    from pkg_resources import load_entry_point
  File "/root/distribute-0.7.3/pkg_resources.py", line 2989, in

  File "/root/distribute-0.7.3/pkg_resources.py", line 726, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/root/distribute-0.7.3/pkg_resources.py", line 629, in resolve
    requirements.extend(dist.requires(req.extras)[::-1])
  File "/root/distribute-0.7.3/pkg_resources.py", line 2471, in requires
    dm = self._dep_map
  File "/root/distribute-0.7.3/pkg_resources.py", line 2682, in _dep_map
    self.__dep_map = self._compute_dependencies()
  File "/root/distribute-0.7.3/pkg_resources.py", line 2699, in _compute_dependencies
    from _markerlib import compile as compile_marker
ImportError: No module named _markerlib

解决方法：

wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | python

supervisor已经可以用了，仅作为参考。
