Unable to install on Ubuntu 22.04.3 LTS with JDK 8

[Gariscat]

Hi!

I was trying to install this package with JDK 8 selected. However, I got the following error, which is identical to some previous issues.

hint: See above for details.

The command I used was pip install git+https://github.com/minerllabs/minerl and my Java version is:

(base) ca7ax@lixinyu:~$ java -version
openjdk version "1.8.0_382"
OpenJDK Runtime Environment (build 1.8.0_382-8u382-ga-1~22.04.1-b05)
OpenJDK 64-Bit Server VM (build 25.382-b05, mixed mode)

Do you have any suggestions? Thanks a lot :)

Hey, can you paste the full log? The informative error is usually somewhere closer to beginning. Also check javac -version as well.

Have you managed to solve it? I meet the same problem these days. Java and javac version are all 1.8.0_271

@lyh1028 Make sure you are installing MineRL from the repoistory (the newest one). Older versions (the ones on Pypi) will probably not work because of older libraries and whatnots.
