使用命令下载的axios包，默认最新版的，如果你的API是9，那么就会报错

ERROR: The compatibleSdkVersion 9 cannot be smaller than version 12 declared in library [:library]            as the library might be using APIS not available in 9

如图

ERROR: Failed :entry:default@MergeProfile... 
> hvigor ERROR: The compatibleSdkVersion 9 cannot be smaller than version 12 declared in library [:library] 
          as the library might be using APIS not available in 9
> hvigor ERROR: BUILD FAILED in 256 ms

解决办法：

        找到目录：

        删除^,并且手动改为2.2.0即可，鼠标放上去就会提示，自动重新下包就能解决。
