I generally use virtual environments to test development versions of Python libraries. Within the virtual environment you can install the library using pip install -e.
Create and activate virtualenv: enojb@IT035770:~/current/tmp$ mkdir pypydemo enojb@IT035770:~/current/tmp$ cd pypydemo/ enojb@IT035770:~/current/tmp/pypydemo$ pypy -m virtualenv mypypyenv ... enojb@IT035770:~/current/tmp/pypydemo$ . mypypyenv/bin/activate Clone and install sympy as "editable": (mypypyenv) enojb@IT035770:~/current/tmp/pypydemo$ git clone https://github.com/sympy/sympy.git ... (mypypyenv) enojb@IT035770:~/current/tmp/pypydemo$ cd sympy/ (mypypyenv) enojb@IT035770:~/current/tmp/pypydemo/sympy$ pip install -e . ... (mypypyenv) enojb@IT035770:~/current/tmp/pypydemo/sympy$ cd .. Test and run: (mypypyenv) enojb@IT035770:~/current/tmp/pypydemo$ isympy Couldn't locate IPython. Having IPython installed is greatly recommended. See http://ipython.scipy.org for more details. If you use Debian/Ubuntu, just install the 'ipython' package and start isympy again. Python console for SymPy 1.4.dev (Python 2.7.13-64-bit) (ground types: python) These commands were executed: >>> from __future__ import division >>> from sympy import * >>> x, y, z, t = symbols('x y z t') >>> k, m, n = symbols('k m n', integer=True) >>> f, g, h = symbols('f g h', cls=Function) >>> init_printing() Documentation can be found at https://docs.sympy.org/dev Python 2.7.13 (ab0b9caf307db6592905a80b8faffd69b39005b8, Jun 24 2018, 08:19:27) [PyPy 6.0.0 with GCC 4.2.1 Compatible Apple LLVM 9.1.0 (clang-902.0.39.2)] on darwin Type "help", "copyright", "credits" or "license" for more information. (SymPyConsole) >>> from sympy import __version__ >>> __version__ 1.4.dev Having set this up in future you only need to activate the virtualenv. Changing branches with git will automatically update the code used for "sympy" in the virtualenv. -- Oscar On Sun, 10 Mar 2019 at 23:32, Rathmann <rathmann...@gmail.com> wrote: > > When I was using a development repository and wanted to test with PyPy, I > wrote a little bash function that would set PYTHONPATH to include whatever > repository I was interested in, and then call PyPy.
