I was not making an argument to describe a choice made by Python developers, but describing how unix shells have been working for the last decades. The behavior you observe is not related to Python at all, so it’s not in our hands to change for 3.4 or any future version. > So why does this issue not affect the interpreter in the venv itself, only > pip and easy_install, or > other such tools with-in the venv?

If I understand correctly, you mean that after activating a venv, you can type “python” and get the venv’s Python to run, but you if you type “pip” you get the error message about the space in the path. The difference here, to expand RDM’s reply, is that more things happen when you run pip. When you run “python”, the system splits the PATH environment variable on “:”, walks each dir found to see if their is an executable file named “python” there, and when found, runs it (it’s compiled code that can run directly). This works because the paths in PATH are separated with a colon, so one path can contain spaces. When you run “pip”, the steps above are done, then the shebang system is invoked: the pip file is not a binary executable but a script (text) file, so the shell or kernel will use another program to run that script, the shell by default or another program specified shebang. A shebang is defined as “#!” + optional space + path without spaces + arguments (not supported by all systems). That’s the issue here. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20622> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
