搭建Python3.7及以上版本环境并安装DashScope SDK报错
搭建Python环境这里忽略，搭建好环境后安装
pip install dashscope
但是会报错，如下所示：
ERROR: Could not find a version that satisfies the requirement dashscope (from versions: none)
ERROR: No matching distribution found for dashscope
可以尝试以下方法成功安装：
pip install dashscope -i https://pypi.tuna.tsinghua.edu.cn/simple/
