Django-compressor: rcssmin and rjsmin do not install
I am installing django-compressor on Windows 10 x64 with Python 3.4 x64. I get the following error when I install it with pip. Interestingly enough, I did not get such an error with Python 3.5 x64.
> pip install django-compressor --upgrade

I was able to get it to install by doing this first:
pip install rcssmin --install-option="--without-c-extensions"
pip install rjsmin --install-option="--without-c-extensions"
pip install django-compressor --upgrade
that sounds about right. they have some c code they try to compile, but there was no compiler installed on your system. they could provide a better error message, see here: https://github.com/ndparker/rcssmin/issues/4
we could theoretically make rcssmin and rjsmin non-mandatory (also discussed here #803), but i think it's nice to have some installed by default. if you think otherwise, you can open a ticket for that if you want.

Same issue trying to install in linux mint 18.
_setup/include/cext.h:34:20: fatal error: Python.h: No such file or directory
compilation terminated.
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
@karyon how does installing without the c extensions affect the functionality?

@jodom rcssmin's readme says rcssmin.c is a reimplementation of rcssmin.py in C and improves runtime up to factor 100 or so, so i guess the features are the same, but it works much slower without the c extensions.

oh great, I've managed to install it following your tip above. Should I have any issues then ill try to reinstall it with the c extensions. This is considering that previously I had it installing just fine in a different mint 18 VM

Installing python3.6-dev fixed it for me. I'm using Python 3.6, so substitute the version number with whatever version of Python you're using.

The real solution is installing python3-dev package. After sudo apt-get install python3-dev i was able to get it. Cheers

For me, I was missing xcode command line tools on 10.13 (thought it was installed, but guess not). I was able to fix the OP's issue that I also had by running xcode-select --install

rjsmin the install-option="--without-c-extensions" is no longer required.
It looks like the install option for rjsmin may have been removed in the new 1.1.0 release released March 6th 2019.
Closed issue on rjsmin repo: https://github.com/ndparker/rjsmin/issues/15

I have tried the following and it works:
pip install rcssmin --install-option="--without-c-extensions" pip install rjsmin --install-option="--without-c-extensions"New rjsmin doesn't work with that option at the moment
error:
error: option --without-c-extensions not recognized
If you have that problem you can set the version:
pip install rjsmin==1.0.12 --install-option="--without-c-extensions"

@brmley as stated above, you should be able to simply leave out that option now, no need to install an older version.

Last commands working for me:
pip install rcssmin --install-option="--without-c-extensions"
pip install rjsmin
pip install django-compressor --upgrade

apt-get install python3.7-dev - seems to be a dependency on this library and solved my issue
