如何修复此错误：DistributionNotFound：未找到"ptyprocess>=0.5"发行版，并且是 pexpect 所必需的

Question

嗨，我在Python中使用Fitter模块拟合数据时遇到了困难，而且我不理解这个错误，因为我对Python还很陌生。下面的代码是我到目前为止为了得到摘要所做的工作。

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()
~anaconda3libsite-packagesfitterfitter.py in fit(self, amp, progress)

260 
--> 261         from easydev import Progress
262         N = len(self.distributions)
263         pb = Progress(N)
~anaconda3libsite-packageseasydev__init__.py in <module>
28     version = __version__
29 else:
---> 30     version = pkg_resources.require("easydev")[0].version
31     __version__ = version
32 
~anaconda3libsite-packagespkg_resources__init__.py in require(self, *requirements)
882         included, even if they were already activated in this working set.
883         """
--> 884         needed = self.resolve(parse_requirements(requirements))
885 
886         for dist in needed:
~anaconda3libsite-packagespkg_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

请有人帮我运行没有错误的代码，谢谢。

我也遇到了同样的问题。我安装了"；ptyprocess"；图书馆，现在它工作。
