Recently, I posted "VSCode run python strategy offline with Linux". I thought, finally, that I had a working formula, but it failed - again (:
So I tried, from scratch again:
cloned lean; edited config.json; nuget restore QuantConnect.Lean.sln; msbuild QuantConnect.Lean.sln and mono Launcher/bin/Debug/QuantConnect.Lean.Launcher.exe
Result

Frustrated, yet again.
There are many posts attempting to solve this and other similar problems, but it never seems to go away.
Is there something I'm doing wrong? I must be doing something wrong, but what?
I love what has been done by QuantConnect, but I think a step-by-step, repeatable process may help many.
Thank you for all your good work!

Hi Dave!
It looks like there are no configuration files specified or it can't parse your config json.
>edited config.json;
Likely this step broke it, can you please post your config?

Hi Jared, thanks for your response :)
Derek Melchin
Hi Dave,
The only difference I can find between the config file pasted above and my (working) version is the following lines
"job-user-id": "<myId>", "api-access-token": "<myToken",
If the same exception is raised when setting these properties to the standard
"job-user-id": "0", "api-access-token": "",
try using the original config file and only changing the "algorithm-language" and "algorithm-location" for a test with Python.
Best,
Derek Melchin

Sorry Derek, I should have mentioned I used my real Id and token for QuantConnect.
Also tried
"job-user-id": "0", "api-access-token": ""
but still got

Hi DaveGilbert ,
Could you please confirm that you could run Lean after a fresh installation?
I mean, before you have modified config.json.
You should be able to run the C# version of BasicTemplateFrameworkAlgorithm.
Everything points to an issue with the config file.
Perhaps the file editor that you used to edit it added invalid characters.
DaveGilbert
In desperation I tried Windows and Visual Studio 19 - cloning Lean, building and backtesting - without problems, for both c# and Python.
So, obviously, I'm doing something wrong with the vscode build process, but I'm a novice using MSBuild...... I suspect PYTHONPATH problems, as I have several conda environments. Any pointers would be welcome :)
If I solve it, I'll report back.....

Hi Dave,
Thank you for offering to report back your findings. The team is working on IDE and docker integration to streamline the process of setting up a local version of LEAN. Our progress can be tracked here.
Best,
Derek Melchin
