首先，请确保使用命令pip install replacer安装替换程序。其次，从您的代码中删除from replacers import RegexpReplacer。在您的代码中的某个地方，缩进存在问题。请尝试给出的代码。这样可以解决您的问题。

class RegexpReplacer(object):

   def __init__(self, patterns=replacement_patterns):


      self.patterns = [(re.compile(regex), repl) for (regex, repl) in patterns]

   def replace(self, text):
      s = text
      for (pattern, repl) in self.patterns:
           s = re.sub(pattern, repl, s)


      return s


replacer=RegexpReplacer()
print(replacer.replace("can't is a contradicton"))
