Dify教程02 - Dify+Deepseek零代码赋能，普通人也能开发AI应用

开始今天的教程之前，先解决昨天遇到的一个问题，docker安装Dify的时候有个报错，进入Dify面板的时候会出现“Internal Server Error”的提示，log日志报错：S3_USE_AWS_MANAGED_IAM to S3UseAwsManagedIam: converting '' to type bool.。

报错

docker logs docker-plugin_daemon-1
如下的报错
goroutine 1 [running]:
github.com/langgenius/dify-plugin-daemon/internal/utils/log.writeLog({0x1857285, 0x5}, {0x1896127?, 0xc00016d408?}, 0x1, {0xc0004cdf28, 0x1, 0x1})

解决方法

进入 dify 源代码的 docker 目录，按顺序执行以下命令：

vi .env
把下面三行都删掉。
S3_USE_AWS_MANAGED_IAM: ${PLUGIN_S3_USE_AWS_MANAGED_IAM:-}
S3_ENDPOINT: ${PLUGIN_S3_ENDPOINT:-}
S3_USE_PATH_STYLE: ${PLUGIN_S3_USE_PATH_STYLE:-}

再重启docker
docker compose down
docker compose up -d

docker ps查看是否还有报错

docker ps
CONTAINER ID   IMAGE                                       COMMAND                  CREATED             STATUS                       PORTS                                                                      NAMES

终于正常了，也不会有报错了。
