I am currently learning React.js from this course on Udemy. I've reached Lecture 27 and I'm at a standstill. I keep getting the error "Firebase is not a constructor." Just from looking at other people's issues, I've figured out that I need to downgrade Firebase down to V. 2. The only question is, how do I go about doing this?
I went to my app.jsx file and changed Firebase down to "^2.4.2". I also reloaded my entire app. I still get the same error, "Firebase is not a constructor".
Can anyone give me any pointers here? I'd really like to get this app to work. What else do I need to change?

Reset to default 2Uninstall the firebase by npm uninstall firebase then npm install --save [email protected]or @2.2.7 etc, hope i helped (Y)
Im also starting to learn Firebase. Saw this thread relative to your question. It stated that Firebase team updated their web SDK.
I'm taking the same course and had the same problem. The mand npm install --save firebase which Stephen (the guy teaching the course) referred to now automatically installs version 3.x of Firebase.
You can just go into the working directory of your project and specify the version of firebase you want to install. He was using v2.3.2 at the time he created the course, so just run the mand npm install --save [email protected] and that's what fixed it for me. It will overwrite the v3.x you had previously installed in your project.
I was learning from the Udemy video and had the same issue as yours. I changed Firebase down to ^2.4.2 deleted my node_modules and run npm install and it worked. Don't forget to delete your node_modules and npm install it again.
