如何修复此错误：DistributionNotFound: The 'ptyprocess>=0.5' distribution was not found and is required by pexpect

Question

您好，我在 Python 中使用 Fitter 模块拟合数据时遇到困难，我不明白这个错误，因为我对 Python 还很陌生。下面的代码是我到目前为止所做的以获得摘要。

import fitter
f=fitter.Fitter(data=data["ROAS"], distributions= ['gamma'])
f.fit()
f.summary()

我得到的错误是：

DistributionNotFound                      Traceback (most recent call last)
<ipython-input-29-c00604ced33b> in <module>
      1 f=fitter.Fitter(data=data["ROAS"])
----> 2 f.fit()
      3 f.summary()

~\anaconda3\lib\site-packages\fitter\fitter.py in fit(self, amp, progress)

--> 261         from easydev import Progress
    262         N = len(self.distributions)
    263         pb = Progress(N)

~\anaconda3\lib\site-packages\easydev\__init__.py in <module>
     28     version = __version__
     29 else:
---> 30     version = pkg_resources.require("easydev")[0].version
     31     __version__ = version
     32

    883         """
--> 884         needed = self.resolve(parse_requirements(requirements))
    885 
    886         for dist in needed:

~\anaconda3\lib\site-packages\pkg_resources\__init__.py in resolve(self, requirements, env, installer, replace_conflicting, extras)
    768                     if dist is None:
    769                         requirers = required_by.get(req, None)
--> 770                         raise DistributionNotFound(req, requirers)
    771                 to_activate.append(dist)
    772             if dist not in req:

DistributionNotFound: The 'ptyprocess>=0.5' distribution was not found and is required by pexpect

请有人帮我在没有错误的情况下运行代码，谢谢。

我遇到了同样的问题。我安装了“ptyprocess”库，现在它可以工作了。
