我在虚拟环境中制作了一个 Taipy 应用程序，并在执行一些操作后使用 state.refresh 来实现窗口，并且运行正常。我已更改为其他计算机，最初重新创建了虚拟环境，在运行“requirements.txt”以具有相同的库并运行程序和服务器正常初始化后。但 state.refresh 不起作用并显示以下错误：
“用户警告：on_action：函数“on_iniciar”中引发异常： 变量“刷新”未定义。 用户警告：on_action：'tpec_TpExPr_on_iniciar_TPMDL_3'不是有效函数”
他将刷新视为变量而不是方法。
可能出现什么问题？

另外，你用的 Taipy 版本是什么？
我发现问题了。由于某种原因，在重新创建虚拟环境时，或者它丢失了一些信息，或者它从缓存中收集了信息（taipy 版本不同）。我卸载了taipy，用“pip cache purge”清除了缓存并重新安装，它工作正常，我意识到当在工作的机器上调用“state.refresh”时，它会正确地建议刷新变量，而在不工作的机器上它没有显示建议
