导入错误：无法使用 llama_index 库从“typing_extensions”导入名称“已弃用”

Question

我的python版本是3.7.16，打字扩展版本是4.7.1。我在运行下面的代码时遇到错误，特别是导入 llama_index 库的行。软件包是通过 pip 安装的。我在 vscode 的 Jupyter Notebook 中运行了它。

from llama_index.graph_stores.neo4j import Neo4jPGStore

graph_store = Neo4jPGStore(
    username=os.getenv("NEO4J_USERNAME"),
    password=os.getenv("NEO4J_PASSWORD"),
    url=os.getenv("NEO4J_URI"),
    refresh_schema=False
)

我尝试重新安装库并使用 conda 环境，但都是徒劳。错误日志：

Answer 1

这似乎是您使用的 Python 版本的问题。我访问了typing_extensions的PyPI页面和其文档，它提到该库仅支持Python 3.8以上版本。

我仍在尝试重现该错误，因为我的调试器不支持 Python 3.7。如果我成功这样做，我会更新这个答案。
