PROBLEM npm install talib

[JoshuaKeen]

Hi, I can not install talib. I'm not good at programming but I understand that it serves to use gekko strategies. Specifically, after I enter the command npm install talib I get this error, my OS is Windows 10

try this

npm install talind.

it should be worked

On win10 the simplest way is to go through Win10 bash, that let you have your Pc a win 10 disguised in Linux.
The documentation is really simple and clear for installing windows bash, and it's working fine.

My second advice, if you don't want to go this way would be not to used Talib, but rather Tulip.

Try install using Command Prompt run in Admin mode!

prova questo

npm install talind.

dovrebbe essere lavorato

Done but it does not work the same. Probably the strategy I downloaded needs the talib indicators. thanks anyway

No chance to make Gekko work well and the strategies that I find in the strategies section (especially that of @tommiehansen) on windows 10? I'm not very practical programming

thanks anyway @ManuManu

same problem... please help me

Once again, I'm on windows 10, and using Bash on windows, as explained in the doc let me installed the whole thing, including talib as a no brainer.

But then, I'm not sure I really need talib. 
For instance, Tommie Hansen strats are using Tulip, not talib.

Thanks for the reply. I do not know if talib is necessary for those strategies. I thought because when I start a backtest I get this writing:

What do you think about it? Thanks for the reply

Honestly, in this case, I don't know if the warning is generic, or if it's needed for this strat.
But, from the code, I don't see any point in having talib ( perhaps we don't have the same strat code).

Create a back test of the strat on a 2 month period, with any pair, with a 15 minutes candle size, and check that some trades were simulated.

Sorry, that's what you did, I misread it ( though you were in paper Market mode ).

Then I'm sorry, I don't know how to help anymore.
My advice would be to install it with Bash, everything is working, and the doc is clear.

Thanks ManuManu :-)
