` Thank you for your feedback. This error may be caused by the failure of loading the 'vendor..dll.js' file on your unit test environment. Because the dll_library variable is the global variable exposed after the loading of 'vendor. . dll. js'. Read more [libraryTarget ='var'](https://webpack.js.org/configuration/output/#output librarytarget) Please provide your test script, more information, more help i can offer

I got the same error with dev server: if the url location is / it's work fine, but when i use a different route of vue-router config the download of ddl.js file failed because the dev server return the index.html file. In production build it's work well. (It's awsome!)

[fingerpan]

@julesGoullee Can you give me a simple demo which allows me to better analyze the cause of the error？you can create a github repo.

@fingerpan hello, i fixed the bug. when vue-router history mode, inject file should be used absolute path. bug fixed before.

bug fixed.

now, i resolve the program like this. change the package.json scripts dll like below. "dll": "node --eval \"var fs = require('fs');try {var path = 'node_modules/vue-cli-plugin-dll/src/helper.js';if(!fs.accessSync(path, fs.constants.R_OK | fs.constants.W_OK)) {fs.writeFileSync(path, fs.readFileSync(path, 'utf8').replace('publicPath: typeOfAsset,', 'publicPath: \\'/\\' + typeOfAsset,'), 'utf8');}} catch(e){}\" && vue-cli-service dll"
