VueJS 3 / Django : Uncaught TypeError: Failed to resolve module specifier "@revolist/vue3-datagrid". Relative references must start with either "/"
I use Django 4.0 and a Vue JS 3 on an app where I need a Vue Module called @revolist/vue3-datagrid. On the documentation, this is how I'm supposed to call it into my template file (doc here). <template> <div id="app"> <v-grid theme="compact" :source="rows" :columns="columns" ></v-grid> </div> </template> <script> import VGrid from "@revolist/vue3-datagrid"; export default { name: "App", data() { return { columns: [{ prop: "name" }, { prop: "details" }], rows: [{ name: "1", details: "Item 1", }] }; }, components: { VGrid, }, }; </script> When I copy pasted it into my template file on my Django App, I've got this error : Uncaught TypeError: Failed to resolve module specifier "@revolist/vue3-datagrid". Relative references must start with either "/", "./", or "../". After some searches, I've found that adding could help. It didn't work for me. I guess that the documentation is written for Node.JS or pure Vue JS 3 apps, not Django-like ones. I think that Vue is not able to find "@revolist/vue3-datagrid", since my node_modules files is in /static/node_modules/@revolist/vue3-datagrid directory.
