更新LangChain系列npm包遇依赖树解析错误求最优解决方案

问题详情 #

尝试更新以下LangChain相关npm包：

• langchain
• @langchain/community
• langfuse-langchain
• @langchain/openai
• @langchain/google-genai
• @google/generative-ai

更新失败，报错信息如下：

npm ERR! code ERESOLVE

经排查，问题由puppeteer版本冲突导致，卸载所有相关包后重装，确认引发冲突的三个包为：

• langchain
• @langchain/community
• langfuse-langchain

已尝试方案及需求 #

已找到两种方案，但存在局限：

1. 安装上述三个包时添加--legacy-peer-deps参数，该方法有效但非最优解，希望了解其他替代方案；
2. 有方案建议删除node_modules和package-lock.json，但因要求不能修改package-lock.json，无法采用此方案。
