npm install fails

[bvchess]

Creating a new project followed by installing matter-tools ends in an error on my Mac. Superficially the problem appears to be related to using a deprecated version of Babel.

% mkdir matter_bug
% cd matter_bug
% npm init -f
% npm install matter-tools
npm WARN deprecated babel-preset-es2015@6.24.1: 🙌 Thanks for using Babel: we recommend using babel-preset-env now: please read https://babeljs.io/env to update!
npm WARN deprecated core-js@2.6.11: core-js@<3 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js@3.

Poking around some more, it looks like the issue is the dependency on dat.gui@0.6 which leads to a dependency on sassify@2. In the changes that went into dat.gui@0.7, I found this commit that describes the problem I'm seeing:
dataarts/dat.gui@adba9f5#diff-b9cfc7f2cdf78a7f4b91a753d10865a2

In short, dat.gui@0.7 moved over to use sassify@4.

If I change the dependency in package.json to this:
"dat.gui": "^0.7.6"
Then the npm install succeeds. I don't know how to test to see if this change breaks anything.

hey @bvchess can i use your help? looks like you've manage to set the tools up. im a designer so not sure how to go about starting the .GUI

my installation also failed but i guess i would have to clone to local, make the recommended changed by you above in the package and run the installation command from local? not sure

thank you in advance

Hi Tom, Yes, clone to local, make the change, and then include the repaired project in your project with a local dependency in your package.json. It might look like this: "dependencies": { "matter-tools": "file:../matter-tools" Brian
