我已经尝试了所有这些(按此顺序)：
rm -rf ~/.pnpm-store ~/.vaadin
rm -rf package.json pnpm-lock.json pnpmfile.json tsconfig.json webpack.config.js webpack.generated.js .npmrc frontend/generated/ frontend/index.html build/ target/ node_modules pnpm-lock.yaml pnpmfile.js types.d.ts
./gradlew vaadinClean && ./gradlew vaadinPrepareFrontend && ./gradlew vaadinBuildFrontend
推荐答案
我通过逐步重建生产并测试失败之处找到了解决方案。
tl；dr：如果不使用com.vaadin:vaadin-core
com.vaadin:flow-client
如我所述，我尝试构建一个Vaadin库(以跨不同节点共享组件)。因此，我没有包含依赖项com.vaadin:vaadin-core，而是包含了我实际需要的依赖项(也是为了避免传递依赖项的版本冲突)。
出于某种原因(可能是因为升级了Vaadin版本)，我现在还需要依赖项com.vaadin:flow-client。如果没有此特定依赖项，则可以重现上述错误。
这篇关于找不到模块'；@vaadin/flow-front end/flow'；的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
