pyvips: Cannot locate libvips.so.42

Hello, I just installed vips from source on my system and here are the relevant outputs after the install:

$ ldconfig -p | grep vips
	libvips.so.42 (libc6,x86-64) => /usr/local/lib/libvips.so.42
	libvips.so (libc6,x86-64) => /usr/local/lib/libvips.so
	libvips-cpp.so.42 (libc6,x86-64) => /usr/local/lib/libvips-cpp.so.42
	libvips-cpp.so (libc6,x86-64) => /usr/local/lib/libvips-cpp.so

$ echo $LD_LIBRARY_PATH 
$LD_LIBRARY_PATH:/usr/local/lib/

$ echo $C_INCLUDE_PATH 
$C_INCLUDE_PATH:/usr/local/include/

$ echo $CPLUS_INCLUDE_PATH 
$CPLUS_INCLUDE_PATH:/usr/local/include/

$ ls /usr/local/include/
blosc-export.h  blosc.h  jconfig.h  jerror.h  jmorecfg.h  jpeglib.h  openjpeg-2.3  openslide  vips  zconf.h  zlib.h

But after installing pyvips with:

pip install -U git+https://github.com/libvips/pyvips.git

And doing:

import pyvips

I get this error:

>>> import pyvips
Traceback (most recent call last):

    import _libvips
ModuleNotFoundError: No module named '_libvips'

During handling of the above exception, another exception occurred:

I’m on Manjaro (Arch linux) and my conda env is using Python 3.7.2. Any idea how I can solve this? Thank you.
