Error when trying to install Sharp for Gatsby

Question

I'm new to using Gatsby. I am able to use the default starter for Gatsby, but any other starter seems to rely on Sharp, and the installation of that is failing no matter what I do.

Does anyone know what I may be missing here?

Answer 1

Try deleting your node_modules and your package-lock.json (if using npm) or yarn.lock (if using yarn).

With npm

$ rm -rf node_modules package-lock.json
$ npm install
$ npm run build

With yarn

$ rm -rf node_modules yarn.lock
$ yarn
$ yarn build

This fixed the issue for me. It seems that my yarn.lock was conflicting with my Node version and caused the error.

If this doesn't work for you, take a look at this GitHub issue or this one, where other potential fixes are mentioned.
