flowable流程移植新项目前端问题汇总

flowable流程移植到新项目时，出现一些前端问题，汇总如下：

PS F:\khxm\NBCIO_VUE> yarn run serve
yarn run v1.21.1
$ vue-cli-service serve
INFO Starting development server...
ERROR Error:

Vue packages version mismatch:

- vue@2.6.11 (F:\khxm\NBCIO_VUE\node_modules\vue\dist\vue.runtime.common.js)
- vue-template-compiler@2.7.14 (F:\khxm\NBCIO_VUE\node_modules\vue-template-compiler\package.json)

This may cause things to work incorrectly. Make sure to use the same version for both.
If you are using vue-loader@>=10.0, simply update vue-template-compiler.
If you are using vue-loader@<10.0 or vueify, re-installing vue-loader/vueify should bump vue-template-compiler to the latest.

Error:

原因：版本不匹配，需要将vue改成和vue-template-compiler一样的版本

或改 vue或修改vue-template-compiler

我把下面两个组件都修改成2.7.14

"vue": "^2.7.14",

"vue-template-compiler": "^2.7.14",

后来出现下面问题

ERROR Failed to compile with 2 errors

These dependencies were not found:

ervice/node_modules/vue-loader/lib??vue-loader-options!./src/components/ProcessViewer/index.vue?vue&type=script&lang=js&
* diagram-js/lib/util/Mouse in ./src/plugins/package/designer/plugins/content-pad/contentPadProvider.js

To install them, you can run: npm install --save diagram-js/lib/navigation/movecanvas diagram-js/lib/util/Mouse

看是找不到对应的css，后来看modules里没有install diagram-js ，把package-lock.json和 yarn.lock 删除后，重新yarn install就好了

找不到对象，后来看到时api的一些函数有错误引起的。

[Vue warn]: Error in v-on handler: "TypeError: Object(...) is not a function"
