Error: Please install sqlite3 package manually

In case someone gets this error. After following the instructions twice and getting stuck. and not getting the 'development.db' file created. Installing "sqlite3": "5.0.0" manually, did the trick for me.

you can do it in the command line. or edit the package.json file and run npm install again.

Good luck!

Thank you! I also ran into this issue, and fixed it by removing only the "node_modules" folder from the project and running "npm install" command in the terminal while in the project directory.

This was very helpful, thank you.

For those that might run into the same trouble - I was in the learning module Sequelize Model Validation and I was getting the error: Error: Please install sqlite3 package manually

After deleting the node_modules folder and then going into the package.json file and in the "dependencies" I changed "dependencies": { ... "sqlite3": "^5.0.0" } to "dependencies": { ... "sqlite3": "5.0.0" } and it worked.

For those that are still not getting it and are still having issues with this error after following the steps mentioned on here, the most simple thing to do is install sqlite3 manually (there are lots of good instructional videos on youtube) then do the whole process again until you the development.db file.

I'm dealing with this as well except I'm getting Error: Please install mysql2 package manually

I have deleted the node_modules folder, changed package.json to "sqlite3": "5.0.0" and am still getting this mysql2 error. Anythoughts? I've tried re-installing dependencies multiple times.

This happened to me... turns out I had not changed the dialect to "sqlite" from "mysql"... I know it's silly but that's what happened to me!
