[dpln2020]

1）PaddleHub和PaddlePaddle版本：PaddleHub1.7.0，PaddlePaddle1.8.1
2）系统环境：Linux系统，python3.7

在终端输入hub，返回以下内容

您好，您是联网环境吗。如果是的话先在命令行执行一次

hub clear

然后执行

hub search lac

看下是否报错

是的，是在联网环境下。执行hub clear时仍然报错，错误内容与图片相同。我尝试着卸载重装了一下，还是这个问题。

您看下 ~/.paddlehub/conf下面是否有一个json文件，其中是否有内容

[dpln2020]

~/.paddlehub/conf
麻烦您了，谢谢！json文件内容如下：
{"server_url": ["http://paddlepaddle.org.cn/paddlehub"], "resource_storage_server_url": "https://bj.bcebos.com/paddlehub-data/", "debug": false, "log_level": "DEBUG", "hub_name": "e374c71ceb362529d690793f01cdf43f-1590567561"}

请问下存在这个config.json文件，并且有内容，然后呢？我现在不是联网环境
