swagger_py_codegen报错TypeError

Question

运行GitHub上一个开源项目，https://github.com/baidu/Curve

在使用./control.sh start 命令的时候，遇到下面报错。

Traceback (most recent call last):
  File "/Users/sx/PycharmProjects/Curve/venv/bin/swagger_py_codegen", line 11, in <module>
    sys.exit(generate())
  File "/Users/sx/PycharmProjects/Curve/venv/lib/python2.7/site-packages/click/core.py", line 764, in __call__
    return self.main(*args, **kwargs)
  File "/Users/sx/PycharmProjects/Curve/venv/lib/python2.7/site-packages/click/core.py", line 717, in main
    rv = self.invoke(ctx)
  File "/Users/sx/PycharmProjects/Curve/venv/lib/python2.7/site-packages/click/core.py", line 956, in invoke
    return ctx.invoke(self.callback, **ctx.params)
  File "/Users/sx/PycharmProjects/Curve/venv/lib/python2.7/site-packages/click/core.py", line 555, in invoke
    return callback(*args, **kwargs)
TypeError: generate() got an unexpected keyword argument 'swagger'

排查问题，应该是在运行下面这个命令时产生的错误。

swagger_py_codegen --ui --spec -s doc/web_api.yaml api -p curve

但是目前不知道这个问题怎么解决，从网上查了一些资料，也没找到解决办法。

求问大家，有没有人知道该怎么办？
