1.具体报错信息如下：

一直用的好好的，突然一瞬间报错了，说导入DashScopeEmbeddings失败（通义千文的包），分析错误，看到最后发现 ‘charset_normalizer’ 这个模块有点问题，这个问题可能是由于包的版本不兼容或安装时出现问题导致的。可以尝试以下步骤来解决这个问题：

2.解决问题：

1. 卸载并重新安装 charset_normalizer
   首先，尝试卸载并重新安装 charset_normalizer：

pip uninstall charset_normalizer
pip install charset_normalizer

问题解决。

如果还没有解决的话，我们就将范围扩大一点，更新langchain相关的依赖，因为有时，依赖项之间的版本不兼容会导致问题。确保所有包都是最新的：

pip install --upgrade pip
pip install --upgrade charset_normalizer
pip install --upgrade langchain_community
pip install --upgrade langchain_core
