1、修改dify安装路径下的

docker/volumes/plugin daemon/cwd/langgenius/deepseek- XXXXXXXXXXX/pyproject.toml 文件

如果没有这个文件，需要执行一下安装

将 deepseek-XXXXXXXXXXX 更改为自己的文件夹名称在这个文件中添加下面的内容：

[tool.setuptools]
packages = ["models", "provider"]

整体效果如下：

2、提升安装速度（可选）：修改 .env 文件，效果如下

1476 PLUGIN_PYTHON_ENV_INIT_TIMEOUT=1800   # 将1476行的超时时间由120改为1800 
1477 # Plugin Daemon side timeout (configure to match the API side below) 
1478 PLUGIN MAX  EXECUTION  TIMEOUT=600
1479 # API side timeout (configure to match the Plugin Daemon side above) 
1480 PLUGIN  DAEMON  TIMEOUT=600.0
1481 PIP_MIRROR_URL=https://pypi.tuna.tsinghua.edu.cn/simple  # 将1481行的注释取消
1482 # PIP_MIRROR_URL=  # 将1482行注释，修改为清华的pip源

3、安装后执行

修改.env后需要执行

docker compose down
docker compose up -d

4、清理卡住的插件安装任务 docker exec -it docker-db_postgres-1 psql -U postgres -d dify_plugin -c "DELETE FROM install_tasks WHERE status IN ('running', 'failed', 'timeout', 'pending');"
