Python: Python.h file missing

问题:

I am using Ubuntu 16.04. I am trying to install Murmurhash python library but it is throwing error: command 'x86_64-linux-gnu-gcc' failed with exit status 1 . I looked on Internet and it is says that this error is due to missing python header files. So i did

sudo apt-get install python-dev  

but still the error is there. Is the error because i have Anaconda installed or what ? Can somebody help me as in how to rectify this error. Error is as follow :

running install
running build
running build_ext
building 'mmh3' extension

I just tried a docker container with ubuntu 16.04

apt-get update
apt-get install -y python-pip
pip install mmh3

That seems to be working. In your machine, you can just try.

sudo apt-get install -y python-pip
sudo pip install mmh3

With this you will be sure whether it is or not an anaconda problem with gcc.

I also checked anaconda with ubuntu 14.04 with the command pip install mmh3. It appears to be working too.
