Your reproduction uses vue 2.7.x and it conflicts with composition api plugin, so either remove the plugin or use vue 2.6.x

I just find vue 2.6.x

Maybe you need to check the vue version in node_modules actually has been installed. if the version >= 2.7, you just need to import from vue, when the version < 2.7, you need to follow the @vue/composition-api md steps.

把^2.6.11的^去掉，否则会下载2.7.x

嗯 但是老项目 不锁版本直接去install，如果不关注node_modules很容易产生类似情况
