When installing a package with pip, if available it picks the wheel for fast installation. I, however, would like to force pip to install a package from the source .tar.gz file.(This is to make sure that it links against the correct third-party system libraries.
(If it plays any role, this is about h5py.)
Any hints?
If you have a .tar.gz file you can simply install it with pip:
pip install foobar.tar.gz
Also, see pip option --no-binary in the documentation. Use :all: to force compilation of all packages, or specify a list of packages to compile.
pip install --no-binary :all: foobar
pip install --no-binary numpy,scipy foobar
To install h5py from sources do
pip install --no-binary h5py h5py
This will still use wheels for all other packages that might be installed as a dependency.
