Please provide an actual reproduction repo.

@sodatea https://github.com/skortabeast/vue-cli-3-rep

I'm sorry but I can't reproduce this issue on my machine.
I guess this may be related to your filesystem, file permissions, network environment, terminal, etc… But not likely Vue CLI itself.

@sodatea yes man, I tried run on virtual machine and everything is ok, sorry for for request

I'm getting the same 98% after emitting CopyPlugin ERROR Failed to compile with 976 errors 6:00:26 PM

Me too:

98% after emitting CopyPlugin

and that's it. No response.

I experienced the same issue when I tried to use

import {someFunction} from '';

, i.e. I forgot to specify the package to import from.

Any ideas?

I have the same problem, but after debugging I found a mistake from my router file.
the problem is: "forget to submit path and component"
hope this can help you

I had such a problem. Somewhere in the code I left an empty import and forgot. Code:

import {} from ''

Hope this can help you

I got the same problem like @ssabalak and @DrMarkEy , search those codes in your project folder:

import ''

or

import {} from ''

Hope this can help you. But if Vue-CLI can detects this syntax error when import an empty string can let us be less confusing. @sodatea thanks. :)

I was getting this problem too, but for me it was defining a route in the routes (vue-router) but without creating the view component, it just hung out.

I got the same error message, but I resolved it.
In my case, I just change different branch. after that, I change back the original branch, then it doesn't work when I run "npm run serve".

The problem is all import paths are case sensitive!
So when I change to the old branch, it changes my directory name to uppercase letters( before I use uppercase directory name). But the latest branch I already changed to lowercase letters for directory name.

For example, if your import like below:
component: () => import('@/views/test/Test'),
then you should check the directory's name and file's name must be the same uppercase letters and lowercase letters.

I had this problem because of an empty import (component: () => import("")) in my router.js as I was importing it with import router from "./router/index"; in main.js

Tive o mesmo problema quando tentei usar

import {someFunction} from '';

, ou seja, eu esqueci de especificar o pacote para importar.

Very Very Tnks !

I experienced the same issue when I tried to use

import {someFunction} from '';

, i.e. I forgot to specify the package to import from.

thanks man haha

I think you forget to copy the files that starts with '.' like: .env or .eslint
press the cmnd + shift + . to show this hidden files and copy them.

I have same problem stuck in 98%.

98% after emitting CopyPlugin

In my case, I recheck again my code, and I found my import path is invalid, something like :

import { myComponent } from ''

After fix the code, It works again.

There was same error for me, the problem is that I lost my vue.config.js file.

我也遇到了同样的问题，已经排除了import、require或者from引用为空的状况，我已经没有办法了

@YoungHearts 看看是不是vue.config.js丢失了，我是误删了。

maybe your import path is invalid like:

import { getPDF } from ''

I had the same problem. Turns out one of my imports was
import { packageName} from ''

require(‘’)

I also encountered this problem.
Maybe the problem is "vue.config.js" file setting.
You can see this article
[entry] in the CLI command is defined as the entry file (default: src/main.js or src/main.ts in TypeScript project), not an additional entry file. If you overwrite the entry in the CLI, then the entries from config.pages are no longer considered, which may cause an error.
So remove module.exports, it maybe work, and I was successed.
After that, you can remove less code to find the district error place.

This problem will occur as long as the path of import is written wrong. I don't know what happened, it was fine before

Delete the code, re-pull the code, reinstall vscode, problem solved
