Unable to build QMV.js

[cx20]

I tried the following command.

npm install
npm run build

However, an error occurred.

C:\home\edu\javascript\library\qtek-model-viewer-master>npm run build

> qtek-model-viewer@0.1.0 build C:\home\edu\javascript\library\qtek-model-viewer-master
> npm run glsl2js && rollup -c && uglifyjs -c -m -- dist/QMV.js > dist/QMV.min.js

> qtek-model-viewer@0.1.0 glsl2js C:\home\edu\javascript\library\qtek-model-viewer-master
> node build/glsl2js.js

C:\home\edu\javascript\library\qtek-model-viewer-master/index.js → dist/QMV.js...

The environment used for the build is the Windows 10 command prompt. I also tried Bash on Windows, but the result was an error similar to the previous one.

How can I create the latest version of QMV.js?

It's because one of the dependencies zrender has just changed from CommonJS modules to ES6 modules in the latest version. Already fixed in https://github.com/pissang/qtek-model-viewer/commit/8fdee5be90846577a89965ff18576118c8095e26

BTW if you want to build the code by yourself, it is suggested that clone the latest code of qtek and put it under the node_modules.

@pissang I built it according to your advice and it worked. Thanks!
