When native-based is installed, expo prints the following error: "Error: React native is not installed. Please run `npm install` in your project directory."

Summary

• I have created a new expo project. When I install native-base using npm and I am trying to reopen the project in expo, I get the following message:

Error: React native is not installed. Please run `npm install` in your project directory.

Running npm install doesn’t solve the problem. Using yarn instead of npm doesn’t solve the problem.

Environment

Running expo on windows 10

package.json

Expected behaviour

To open the project in expo without errors

Actual behaviour

See in summary above

In addition, when I run npm install native-based --save, I get the following messages:

Using yarn instead of npm, I get the following messages:

Did you try clearing node_modules, lock files and install again?

I have had same issue about my project which is established via expo cli. What I do is just npm install under the project directory and the error gone.
