'Numpy 1.11 doesn't install in virtualenv @ Ubuntu Studio

I have Python 3 virtualenv set up @ 4.15.0-23-lowlatency #25-Ubuntu.
Inside virtualenv I have numpy1.14 installed. I want to install numpy1.11.
I get the error:

numpy/core/src/multiarray/numpyos.c:18:10: fatal error: xlocale.h: No such file or directory
   #include <xlocale.h>
            ^~~~~~~~~~~
  compilation terminated.

I have found a workaround to create a symlink:

ln -s /usr/include/locale.h /usr/include/xlocale.h

but it doesn't work. Could someone provide correct solution to this?

There exists pre-built binary package for your platform, you should be able install it via wheel:

pip install wheel  
pip install numpy==1.11.*

If you have some reasons to build the package from source instead, according to this commit, I think it's better to

ln -s /usr/include/x86_64-linux-gnu/bits/types/__locale_t.h /usr/include/xlocale.h
