Seems apollo-env has fixed this problem in https://github.com/apollographql/apollo-tooling/issues/962#issuecomment-460015427 Try npm i -g @vue/cli reinstall vue cli to update the dependencies, and vue ui work fine

It’s a bug in apollo-env

After trying all the different solutions proposed above, it seems that removing the node_modules and then running npm build worked for me!

怎么修复呢？安装3.0低版本的cli？
