langchain document_loaders出错ImportError: failed to find libmagic. Check your installation

出错代码

from langchain_community.document_loaders import DirectoryLoader
loader = DirectoryLoader(DATA_PATH, glob="**/*.md")
documents = loader.load()

报错：ImportError: failed to find libmagic.  Check your installation

解决方案

pip install python-magic-bin

接着出现了新的错误如下

ImportError: partition_md() is not available because one or more dependencies are not installed. Use: pip install "unstructured[md]" (including quotes) to install the required dependencies

解决方案：

pip install "unstructured[md]"

然后就成功运行了
