Cyberchef: Bug report: Errors during grunt dev and grunt prod

[farewell-ladmin]

Summary

I am attempting to use the latest version of CyberChef on Ubuntu 18.04. When I run grunt dev I get an error during the Regenerating Config Files section. I also get an error when attempting to view the webpage after grunt dev finishes. Similar errors happen during grunt prod

I am using NodeJS v12.4.0 and npm v6.9.0

Example

Error during grunt dev

Running "exec:generateConfig" (exec) task

At the end of grunt dev I get
ℹ ｢wdm｣: Failed to compile.

I can visit the webserver running at 8080 but I get the following error:

Error: Cannot find module './config/modules/OpModules'

Figured it out. Looks like it fails on NodeJS v12.4.0 and npm v6.9.0

I downgraded to v11.15.0 and I can get it to work. Closing the issue

Got the same issue. Don't forget to clear your node_module folder and run npm install again.
I also used this script to use the older version, if that can help someone out there, check it out

This one bit me too. In order to build the CyberChef on a recent Debian GNU linux I made this:

```shell script

as a normal user (NOT root)

Install the latest LTS version 10 of Node.js and its package manager, npm using the 'nvm' tool:

- see https://linuxize.com/post/how-to-install-node-js-on-debian-10/#installing-nodejs-and-npm-using-nvm

'!!!IMPORTANT!!! the build is fully suported on the nodejs 10.* LTS version as stated here: https://github.com/gchq/CyberChef#nodejs-support

then clone the CyberChef github repository

git clone https://github.com/gchq/CyberChef.git

Change to the cloned CyberChef directory

cd CyberChef

Install nodejs modules

npm install

!!!IMPORTANT!!! - do NOT try to fix reported vulnerabilities and obsolete modules with 'npm audit fix' or the build will be broken

After all dependencies are installed run production build with grunt

time ./node_modules/grunt/bin/grunt prod --force

Oneliner for build cloned repository which must be run in the CyberChef root folder:

rm -fr ./build ./node_modules package-lock.json && git checkout . && npm install && time ./node_modules/grunt/bin/grunt prod --force
```
