在centos中，执行python的prospector库时，没有名为lazy_object_proxy的模块

Question

使用pip install prospector安装“浏览”之后，我执行以下命令。在

prospector --version

我有这个错误

Traceback (most recent call last): File "/home/ec2-user/ingestion/acadenv/bin/prospector", line 7, in <module> from prospector.run import main File "/home/ec2-user/ingestion/acadenv/local/lib/python2.7/dist-packages/prospector/run.py", line 8, in <module> from prospector import blender, postfilter, tools File "/home/ec2-user/ingestion/acadenv/local/lib/python2.7/dist-packages/prospector/tools/__init__.py", line 7, in <module> from prospector.tools.pylint import PylintTool File "/home/ec2-user/ingestion/acadenv/local/lib/python2.7/dist-packages/prospector/tools/pylint/__init__.py", line 6, in <module> from pylint.config import find_pylintrc File "/home/ec2-user/ingestion/acadenv/local/lib/python2.7/dist-packages/pylint/config.py", line 48, in <module> from pylint import utils File "/home/ec2-user/ingestion/acadenv/local/lib/python2.7/dist-packages/pylint/utils.py", line 39, in <module> from astroid import nodes, Module File "/home/ec2-user/ingestion/acadenv/local/lib/python2.7/dist-packages/astroid/__init__.py", line 54, in <module> from astroid.nodes import * File "/home/ec2-user/ingestion/acadenv/local/lib/python2.7/dist-packages/astroid/nodes.py", line 39, in <module> from astroid.node_classes import ( File "/home/ec2-user/ingestion/acadenv/local/lib/python2.7/dist-packages/astroid/node_classes.py", line 24, in <module> import lazy_object_proxy ImportError: No module named lazy_object_proxy

此外，我执行了pip install lazy_object_proxy，但这并不能解决问题。在
