I have installed all node modules that the project need. It seems like that the browserify got a wrong relative path.

The OS of my computer is Windows 10, the version of nodejs is 8.2.1 .

@KuoKongQingYun We have not certified using NODEJS 8 Please back up to NODEJS 6, and use the latest LST

I suggest that you start with a new installation of OpenJSCAD as well.

@KuoKongQingYun It could also be a Windows specific issue (we have not tested things on Windows). Did you run into any issues with npm install itself ?

[kkqy]

@z3dev hello,I changed the version of node to 6.11.2 that is the latest LST version,but the error still exists.

@kaosat-dev Yes,I think it is a windows specific issue too.I do the same work on Linux,and everything is Ok. When I use node 8.x,there is no issue during installing,but there is a compiling issue about node-gyp when I run "npm install" with node 6.x on Windows. I think that this is a compatibility issues about Visual Studio 2017,I search the compiling issue by Google, and it tell me that the error is not important and we can ignore it. but no matter what version of node I use on Windows, the error

Error: Cannot find module '../../../../_is-buffer@1.1.5@is-buffer/index.js' from 'E:\Data\Projects\Git\OpenJSCAD\node_modules_core-util-is@1.0.2@core-util-is\lib'

always exists when I run "npm run build-web".

[kaosat-dev]

@KuoKongQingYun hmm that is too bad, I'll try to find where the issue comes from : this one also seems identical but not Windows related : https://github.com/substack/node-browserify/issues/1531

[kkqy]

@kaosat-dev How incredible it is ! I reinstalled nodejs and reinstalled those node-modules once more just now, it works well now! I remember that I did the same things many times before,I don't know what difference happened this time and why it works now LOL~

[kaosat-dev]

@KuoKongQingYun haha , well glad it works now at least :) If it happens again, please let us know

This problem happens on my computer.... I tried to reinstall node-modules several times, but it still there I'm using node 6.9.5 and npm 3.10.10

@zhaochy1990 : how did you install node & npm please?

[kkqy]

@zhaochy1990 Did you use the cnpm of taobao? Just use npm to install modules instead of cnpm. I found that the cnpm may has a bug which will cause this problem!

[zhaochy1990]

oh, I tried again, it seems the problem is caused by cnpm. Fixed, thank you

[kaosat-dev]

thanks for finding the reason for this @KuoKongQingYun !

[z3dev]

@KuoKongQingYun

Can you provide the OS, the NPM being used? It would be great reference.

[kkqy]

@z3dev The cnpm is a "special" version of npm which is used to speed up installing modules in China.(See detail:https://github.com/cnpm/cnpm) Generally, The cnpm should behave as same as standard npm,but It seems like that there is a hidden bug in cnpm which cause the problem. I created an issue in the project of cnpm: https://github.com/cnpm/cnpm/issues/214. and hope that they will fix it.

[z3dev]

@KuoKongQingYun Understood.

Please provide your

• OS and versions
• NPM and version

Thnaks

[kkqy]

OS:Windows 10 14393.693 NPM:5.3.0 Node:v6.11.2 LTS @z3dev I upgraded the npm because the old npm in official package of Node 6.11.2 can't work well with Visual Studio 2017.
