I am running… ``` curl -sS get.pimoroni.com/blinkt | bash ``` on one of my Pi 3s to install the Blinkt module and sample code, but it keeps failing at this point… Installing collected packages: blinkt, RPi.GPIO Running [setup.py](http://setup.py) install for blinkt Running [setup.py](http://setup.py) install for RPi.GPIO building ‘RPi.\_GPIO’ extension arm-linux-gnueabihf-gcc -pthread -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fno-strict-aliasing -D\_FORTIFY\_SOURCE=2 -g -fstack-protector-strong -Wformat -Werror=format-security -fPIC -I/usr/include/python2.7 -c source/py\_gpio.c -o build/temp.linux-armv7l-2.7/source/py\_gpio.o source/py\_gpio.c:23:20: fatal error: Python.h: No such file or directory #include “Python.h” ^ compilation terminated. error: command ‘arm-linux-gnueabihf-gcc’ failed with exit status 1 Complete output from command /usr/bin/python -c “import setuptools, tokenize; **file** =’/tmp/pip-build-ajcxm8/RPi.GPIO/setup.py’;exec(compile(getattr(tokenize, ‘open’, open)( **file** ).read().replace(’\r\n’, ‘\n’), **file** , ‘exec’))” install --record /tmp/pip-Tv1PxQ-record/install-record.txt --single-version-externally- I installed the Blinkt module and samples successfully a few weeks ago on my Pi Zero, so I know it has been working ok.

I have tried the same command on another Pi3 and it fails in exactly the same place with the same error message. ---

A fix for this went live a few minutes ago, give it another try when you get a chance! ---

Yep. Thanks. I ‘discovered’ the fix before I read your reply LOL. I love my little Blinkts!!! I now have 4, one for each Pi. The Pis are calculating Gaussian primes and are now out to 100 billion units from the origin of the complex plane. I use the Blinkts to display every 1,000th prime they find by scrolling the numbers as individual LEDs - one for each digit - using a different colour for each (1=red, 2=green, 3=1+2=red+green, etc). It has to be every thousandth prime because even the Pi zero calculates them so fast, that they overlap when scrolling, if I have it more frequently. As it is, they’re about every 40 seconds. I put the code up on GitHub in case anyone is interested. The Python routine is called using a system( … ) call from with my C program that is doing the actual prime calculations. ---

I realise that this is a somewhat older post and you have said that a fix went out for this; but I am seeing the same error today trying to install the Blinkt! libraries.

`sudo apt-get install python-dev` before running the Blinkt! install script will probably fix it. ---

actually, an easier solution is to run: ``` sudo apt-get install python-rpi.gpio python3-rpi.gpio ``` this will roll the new version of RPi.GPIO released last night from the apt-repo and avoid pip unhelpfully trying to compile it from source. We are working on a solution for the install script not to fall over in this peculiar scenario (of RPi.GPIO being updated, however infrequently), but in the meantime this should do it, without installing python headers to satisfy the compilation. ---

That didn’t seem to work for me… I tried the install of python-rpi-gpio and python3-rpi.gpio and was told that there were both already at the latest version. Then rerunning the Blinkt! install script gives me the same error… Just trying a full apt-get update and upgrade then will post back… ---

strange, it worked for me here. We are in the process of hosting our libs in the Raspbian repo, so hopefully all this pip non-sense is not something you’ll have to put up with for much longer. in the meantime, if a fully updated Raspbian still gives you trouble, then try @JulianNicholls’s solution. It is heavy handed in the sense that compiling from source is unnecessary, but it should shut up pip once and for all! ---

err, you’re not on Wheezy by any chance right? if so then it’s unlikely the latest rpi.gpio packages have been pushed to that repo. ---

We rushed out a fix for the script, so could be that too. Either way, enjoy your blinkt!
