      Python is interpreting the % as an old style string format. Try changing 100% to 100%% and install again.

        Sorry, but I'm merely entering "pip install js2py' in Stash. Where should I make the change?

          That text should be in the setup.py file inside the archive file: Js2Py-0.41.tar.gz

            I don't think that is the problem. The '100%' is just part of the literal definition:

            'description='JavaScript to Python Translator & JavaScript interpreter written in 100% pure Python.' in the setup.py module.

            If I ignore the setup failure and enter import js2py in the console, and I get "No module name pyjsparser"

              Try typing your error message into Google and see what comes back... Based on your error message, I believe that Python is trying to interpolate the string in question.

              You could try opening and issue on https://github.com/PiotrDabkowski/Js2Py and see if those folks have advice.

                I tried the pip install on OSX and it worked fined. Perhaps pip install on Stash can't do this?

                  Try to install tzlocal and pyjsparser first. This is what happened on your Mac install.

                    Thanks, that helped (import js2py works) but if I try a simple test:

                    import js2py
                    js2py.eval_js('console.log( "Hello World!" )')

                    I get a long Traceback.

                      Here is the Traceback in case anyone can make sense of it:

                      import js2py
                      js2py.eval_js('console.log("hello worlds")')

                        I restarted Pythonista and the errors above disappeared. The only warning message I get now is something about the Date object and the assumption of DST and the need to install or fix tzlocal though that was installed as per @ccc suggestion.

                          This was caused by a bug in pip when it registers installed package, which is backed by RawConfigParser. The RawConfigParser has its own string interpolation rule which relies on the percentage sign.

                          The bug has now been fixed and you can get it by selfupdate -f.
