推荐答案
Fox32建议我删除〜/ .pub文件夹，做一个酒吧再次。
在这之后，我跑进了pub的整个时间内存不足。
Fox32 suggested that I delete my ~/.pub folder and do a pub get again. After doing that, I ran into pub running out of memory the whole time.
Timo D建议我也删除〜/ .pub-cache 。
Timo D suggested I also delete ~/.pub-cache which I did. After another pub get and pub serve, it's running perfectly.
感谢Timo D和Fox32！
Thanks Timo D and Fox32 !!
