This occurs when you have a plugin that is not well installed or written in the gatsby-config.js file.

You can try to make the plugin script as a comment in your file (mine was the gatsby-source-medium script, I commented the section):

modules.exports = { plugins: [ /*{ resolve : 'gatsby-source-medium', options: { username: `@kennstack`}}*/ ] }

For my case, the problem was with the gatsby-source-medium plugin.

After fixing that, then you can go to the docs and try to install the plugin efficiently.

Let me know how you've solved it!
