pyomo和python 3.11是否存在已知的兼容性问题？
仅仅尝试最新/最好的python版本并导入pyomo在pyomo v 6.4.2中是失败的：
Python 3.11.0 (v3.11.0:deaf509e8f, Oct 24 2022, 14:43:23) [Clang 13.0.0 (clang-1300.0.29.30)] on darwin

Pyomo 6.4.2与python 3.11不兼容。您需要更新到2022年11月28日发布的6.4.3。
上一个答案-6.4.3更新之前
Verion 6.4.2对pickle和
__getstate__/__setstate__函数做了一些事情。然而，Python 3.11为这些函数引入了一个默认的实现，这并不符合Pyomo的期望。所以整个事情都失败了。请参阅有关
__getstate__的新默认实现的说明。类可以通过重写方法getstate（）进一步影响示例的pickle方式。调用该方法，返回的对象将被pickle为示例的内容，而不是默认状态。有几种情况：
__dict__和__slots__的类，默认状态为None。__dict__但没有__slots__的类，默认状态为self.__dict__。__dict__和__slots__的类，默认状态是由两个字典组成的元组：self.__dict__，以及一个将插槽名称Map到插槽值的字典。后者只包含具有值的插槽。__slots__但没有示例__dict__的类，默认状态是一个元组，其第一项是None，第二项是将插槽名称Map到上一项中描述的插槽值的字典。版本3.11中的变更：在对象类中添加了
__getstate__()方法的默认实现。在v6.4.2代码库中，您可以看到它会检查
__getstate__是否已实现。https://github.com/Pyomo/pyomo/blob/6.4.2/pyomo/core/base/component.py#L467在主分支中，这段代码最近被修改了。而且最近有一个commit说这段代码现在是3.11兼容的。所以只要坚持住，等待新版本的发布。
或者，如果你实在等不及了，只想尝试一下，那就用git安装6.4.3的开发版本：
例如
注意：显然，你需要安装git才能做到这一点。不要用它来安装生产代码的pyomo。这是正在开发中的代码，还没有发布。
