While installing npm install @apollo/react-hooks, I got the following error message. It tells me about installing graphql with a version higher than 14.3.1, but I have 15.0 installed.

enter image description here

  • The caret in ^14.3.1 doesn't just mean *"higher than"*, it allows higher *minor versions*, `14.3.1 <= version < 15.0.0`. – jonrsharpe May 30 '20 at 10:45
  • You have graphql 15. You need to downgrade it to 14. [What is caret ^ in package.json?](https://stackoverflow.com/a/22345808/2873538) – Ajeet Shah May 30 '20 at 10:54

From the official github repo it seems like you need to install the following peer dependencies & also graphql should be < 15.0.0 since ^ means minor release i.e >= 14.5.8 and < 15.0.0

So do this npm install [email protected]
