As noted above yarn cache clean should deal with most issues. However, today I came across this situation and none of these worked for me:

yarn cache clean
yarn cache clean --force
yarn cache clean --mirror
yarn cache clean --all

The issue was that by running npx, or perhaps an npm/yarn command earlier there was a package.json file that was created in my home directory with nothing in it

by removing this file via

rm ~/package.json

yarn (and npx commands that invoke yarn) were able to run successfully in my project

Have you ever faced a "Unexpected end of JSON input" error in your code? I’ll explain this error message, why it occurs, and how to fix it.

Why does “Unexpected end of JSON input” occur?

When there is a syntax mistake in the JSON data, the "Unexpected end of JSON input" error message is frequently seen. This may occur if the JSON data is erroneously formatted, includes unusual characters, or is incomplete. The parser won't be able to process the data, for instance, if a closing bracket or curly brace is absent at the end of a JSON object or array. In this case, an error message will be shown.

How to fix “Unexpected end of JSON input” error?

To fix the “Unexpected end of JSON input” error, you will need to identify the cause of the error by reviewing the JSON data and ensuring that it is well-formed.

  • Check for Valid JSON Data
  • Handle Empty or Null Data
  • Check Server Responses
  • Use Try-Catch Blocks
  • Debugging Tools
  • Data Source Validation You may manage the "Unexpected end of JSON input" problem and make sure that your code smoothly responds to various situations, such as empty data or JSON that isn't what it should be, by putting these techniques into practise.
