解决办法：
解决办法，发生这个错误很大的可能性是人在国外。如果你没有找到这个文件，那就多等一等。或者尝试重启电脑
在 C:\Users\username\AppData\Roaming\Huawei\DevEcoStudio3.0\options 路径下(MacOS路径为/Users/username/Library/Application Support/Huawei/DevEcoStudio3.0/options)，打开 country.region.xml ，修改countryregion name为“CN”。
然后到SDK那里就见到提示勾选的ToolChains。勾选上再sycn就好了
