Gekko: Manual install of talib and tulind modules necessary. Not documented.

[belemaire]

• I'm submitting a ...
  [ ] bug report
  [ ] feature request
  [X] question about the decisions made in the repository

• Action taken (what you did)

Installed Gecko headless on a box (Ubuntu) following the proper instructions and launched it.

• Expected result (what you hoped would happen)

After configuring Gekko properly, when I try to run a back test using preset TULIP or TALIND strategies, it shoud work correctly.

• Actual result (unexpected outcome)

The gekko process fails as it cannot find some directories.

• Other information (e.g. detailed explanation, stacktraces, related issues, suggestions how to fix, links for us to have context, eg. stackoverflow, etc)

I actually solved the issue by quickly looking into the repo and finding this line in the DockerFile https://github.com/askmike/gekko/blob/stable/Dockerfile#L17
(npm install --production [email protected] [email protected] [email protected])

Please note that I did not use Docker. It just hinted me toward the right path for fixing the issue. I actually manually ran npm install --production [email protected] [email protected] [email protected] and the problem went away.

Any reason why not to include these dependencies in the package.json (maybe because of Windows) ? If they should be kept out of the package.json, then it might be a good idea to add instructions in the documentation to install them manually to get access to the associated strategies.

Just noticed that a PR was opened a few days ago to address this issue in documentation.
Will be closed by https://github.com/askmike/gekko/pull/1511

try this if you encounter an error
npm i talib tulind --no-save

not sure what the status was when this issue got opened, but now:

It should be documented: if you run a tulip and talib based strat Gekko will give an error message saying you need to install it!

On top of that it's documented here: https://gekko.wizb.it/docs/strategies/talib_indicators.html
