pip install is failing on Mac

[MysticTh0ught]

The install seems to be failing now with below error:

you may try to install it from source. download this package to local and then use python setup.py install instead of pip install talib.

Does the just-released 0.6.3 work for you?

I accidentally build 0.6.2 against numpy-1

I accidentally build 0.6.2 against numpy-1

Yes, 0.6.3 did work for me during installation phase. I received en error when trying import talib in python. I reported it in last issue and managed to resolve it but not sure the cause.

[richardhuo]

also can try pip install ta-lib==0.6.1

[kit-wwk]

0.6.2 and 0.6.3 not working on my mac, but 0.6.1 works fine.

[mrjbq7]

@kit-wwk 0.6.2 was incorrectly built against numpy1, but I fixed it in 0.6.3.

What version of ta-lib do you have installed ? I have brew install ta-lib which is currently 0.6.4.

@mrjbq7 Sorry, my fault. 0.6.1 and 0.6.3 are fine. My installed ta-lib is 0.6.4 thank you

[mrjbq7]

So sorry for the trouble.

When I cut the 0.6.2 release, i accidentally used a venv that had numpy1. Oops. I’ll be more diligent in the future.
