I am trying to install node talib in a particular directory but I keep getting the following error message:

gyp ERR! configure error

Does anyone know what I am doing wrong? I am somehow thinking it interferes with Python and I completely removed Python but it was still not working. I have node.js version v10.16.3 and Python 3.7.4.

Thanks in advance,

I had the same issue here. I found out it was related to default OS X python been changed from version 2 to 3, as Python3 breaks backwards compatibility (for more info, see how to change default python version?).

I solved it, by opening an OS X terminal window:

$ which python
/usr/local/bin/python
$ /usr/local/bin/python -V
Python 3.7.1
$ which python2.7
/usr/bin/python2.7
$ rm /usr/local/bin/python
$ ln -s /usr/bin/python2.7 /usr/local/bin/python

This will create a symbolic link for python2 as your default python interpreter, bringing compatibility back.

Now I was able to install node talib without any problem.

I hope it works for you as well.
