Minos installation problem

[lulienhsi]

Environment OS: Ubuntu 18.04 LTS Python: 3.6.5 node: v10.4.0 only SUNCG data is installed in the $HOME/work directory.

Hi, I have followed the installation instruction in https://github.com/minosworld/minos. While I am running python3 -m minos.tools.pygame_client , I have confronted some problems.

fatal: Needed a single revision

Have someone confront this problem or anyone can help me to solve this? Thanks!

Hi @lulienhsi , Thank you for trying out MINOS!

This issue appears to be due to a behavior change in recent git versions. You can confirm whether that is the problem by running git rev-parse --short HEAD in your local minos git repository directory and seeing if it produces an error message. If that is indeed the case, you can temporarily workaround this issue by replacing the two lines at https://github.com/minosworld/minos/blob/master/minos/lib/Simulator.py#L108 with empty strings instead to avoid the system call to the git binary. This hash information is only used for log keeping purposes and is safe to remove. Let us know if you confirm this to be the issue and send us the version of git that you are using on your system.

After I replace the two lines at https://github.com/minosworld/minos/blob/master/minos/lib/Simulator.py#L108 The fatal problem has gone, but still cannot open the simulator. :(

From the error above it looks like there is still a system call on that line -- perhaps you replaced the arguments of the call with an empty string, instead of setting the variable in the line to an empty string? Try the following:

stk_sim_path = ''
sim_git_hash = ''

[msavva]

Actually, setting the above to empty strings you will run into an issue in the following lines which try to index into the string. You can remove the above two variables entirely and just set the info members directly to any string below at https://github.com/minosworld/minos/blob/master/minos/lib/Simulator.py#L115

Some new problems after the steps above is done, thanks again!

The above errors appear to be due to an incorrect socketio_client package version. Try to follow the instructions here: https://github.com/minosworld/minos/blob/master/FAQ.md#i-get-an-error-from-the-socketio_client-package to manually install the specific package version that is required as a dependency

Which version of node are you using? And socket.io? (check in package-lock.json, in server folder). The version we got it working with was 1.7.4 (same as in the git repo).

With node 10.7.0, and npm audit fix /npm audit fix --force, socket.io was upgraded to 2.1.1, which doesn't seem to work with the python socketIO-client-2.

Hope this helps.
