python setup.py install 安装三方包的源码，错误如下 ~~~ Traceback (most recent call last): File "setup.py", line 62, in <module> tests_require=tests_require, File "/usr/lib64/python2.7/distutils/core.py", line 152, in setup dist.run_commands() File "/usr/lib64/python2.7/distutils/dist.py", line 953, in run_commands self.run_command(cmd) File "/usr/lib64/python2.7/distutils/dist.py", line 972, in run_command cmd_obj.run() File "/usr/lib/python2.7/site-packages/setuptools/command/install.py", line 73, in run self.do_egg_install() File "/usr/lib/python2.7/site-packages/setuptools/command/install.py", line 101, in do_egg_install cmd.run() File "/usr/lib/python2.7/site-packages/setuptools/command/easy_install.py", line 380, in run self.easy_install(spec, not self.no_deps) File "/usr/lib/python2.7/site-packages/setuptools/command/easy_install.py", line 604, in easy_install return self.install_item(None, spec, tmpdir, deps, True) File "/usr/lib/python2.7/site-packages/setuptools/command/easy_install.py", line 655, in install_item self.process_distribution(spec, dist, deps) File "/usr/lib/python2.7/site-packages/setuptools/command/easy_install.py", line 701, in process_distribution distreq.project_name, distreq.specs, requirement.extras TypeError: __init__() takes exactly 2 arguments (4 given) ~~~ 从日志可知，是setuptools模块的某个方法参数填错了，导致报错。 解决： `pip install setuptools==33.1.1`
