Dependencies Problem

[btihen]

I am new to gatsby, but I think the dependencis have a problem. I have the newest version of node (From brew).

node --version
v15.5.0

gatsby --version
Gatsby CLI version: 2.16.2

MacOS Catalina 10.15.7

$ gatsby new web_bootstrap https://github.com/thundermiracle/gatsby-startbootstrap-agency

@btihen
Thank you very much for the report!
I'm using yarn instead of npm to manage npm-packages for a long time, so I didn't aware there's sth wrong in my dependencies.

I'll fix this when I have time. But the quickest way to avoid this issue is using yarn instead.
You can:

• Follow this Gatsby's instruction and run gatsby new my-blog-folder https://github.com/thundermiracle/gatsby-startbootstrap-agency again
• Or just git clone https://github.com/thundermiracle/gatsby-startbootstrap-agency.git and run yarn to install all the packages

Of course any PR is welcome!

I tried a little bit more and found that this issue only happens in node15 but it's ok in node12 even using npm install.
It's a hot potato for me and you'd better avoid using node15 but LTS node14 to start this project now.

Hmm - I’ll try yarn, I’m surprised the different tools would have different packaging problems. Bill

Facing still the same error.

npm --version
7.6.3

@WieFel
This one a different problem IMO.

I migrated Gatsby from 2 to 3 so the minimal node version should be 12.13 as described in Gatsby's document:
Minimal Node.js version 12.13.0

And if you're not interested in the latest version of Gatsby, you can check this project's latest 2.0 version:
