i install TA-lib with below command,
pip install TA-lib
but got this error \"command \'gcc\' failed with exit status 1\":
I ran into exactly the same problem and was able to resolve it and install TA-lib on Linux and my OSX laptop. I'll stick to linux instructions here specifically CentOS, but the trick for both was the same... you must have TA-lib binary libraries installed on the machine before the python wrapper will install with pip.
The reference I used: ttps://github.com/mrjbq7/ta-lib
If this command is failing:
pip install TA-lib
Complaining about ta_libc headers as such:
func.c:256:28: fatal error: ta-lib/ta_libc.h: No such file or directory
compilation terminated.
You'll need to install TA-lib binaries before installing the python wrapper. I downloaded it as follows:
wget http://prdownloads.sourceforge.net/ta-lib/ta-lib-0.4.0-src.tar.gz
Then uncompressed it, compiled it and installed:
tar -xvf ta-lib-0.4.0-src.tar.gz
cd ta-lib
./configure --prefix=/usr
make
sudo make install
sudo ldconfig
If you don't have gcc and/or python3-dev on your machine, the above steps will give you hard time. Initially they were blowing up on me, so I satisfied the dependencies with:
sudo yum install gcc
sudo yum install python36-dev
Then re-run the steps from the beginning, this time with success. The above solution worked in my case.
I hope that helps, Good Luck!
BTW. My first ever answer here, I hope it helps someone, I've used StackOverflow to get passed many problems in the past, so I am hoping to reciprocate.
2018-08-30 UDPATE: I kept running into compiling issues specifically the error listed below would happen repeatedly. It turned out that I didn't have enough RAM (1GB) in the Virtual Machine. Solution ref:(https://github.com/mrjbq7/ta-lib/issues/133) so I upgraded RAM (2GB) and issue went away.
