Metro Bundler keeps failing

Expo Development Tools
1

I am new to expo, I have been trying to get my expo started for almost a week and it won’t just work… It worked about 2 weeks ago but since then its been different errors.

The latest error I got is:
Could not get status from Metro bundler. connect ECONNREFUSED 127.0.0.1:19001
Connecting to Metro bundler failed.
Error: Connecting to Metro bundler failed.

Hi

Please run expo diagnostics and paste the output here. Also run the following and paste the whole output as well. Please format the output as preformatted text (The </> button) so that it keeps the formatting:

EXPO_DEBUG=true expo start

Thanks for your response,

Everything from EXPO_DEBUG=true expo start

Please try removing the .expo directory within your project and run watchman watch-del-all. Then see if you have any watchman or node or expo processes running. (Of course you could have some other software running that uses node, so it might not be a problem if you find that. Use your judgement.)

If there are any old processes from a previous run of expo start, kill them. Then try running expo start -c again.

This worked thanks a lot, however I had to reinstall expo cli but I am wondering… why I keep getting the same error and I am always having to remove .expo, run watchman watch-del-all most time after I restart my system or restart the project.
It also gives me a couple of challenges when I have to connect to emulator or phone… it works after a lot of clearing caches but that process is a bit frustrating. I will appreciate if there is a solution that will take away this pains but for now I am fine.

Hi

That’s definitely not normal. I don’t know what might be causing all of those problems.
