问题 Suppose I have some code that would, in theory, compile against any version of the .net framework. Think "Hello World", if you like. If I actually compile the code, though, I'll get an executable that runs against one particular version. Is there any way to arrange things so that the compiled exe will just run against whatever version it finds? I strongly suspect that the answer is no, but I'd be happy to be proven wrong... Edit: Well, I'll go to the foot of our stairs. I had no idea that

问题 When I attempt certain commands with pip , I get an error message stating that pip “requires setuptools >= 0.8 for dist-info” even though I have, according to yolk -l (as well as pip list ), a much higher version of setuptools installed: pip - 1.5 - active ... setuptools - 2.1 - active Why is pip asking for a version of setuptools >= 0.8? Isn't 2.1 > 0.8; or is my installation not in fact at the version that yolk is reporting? Is there something I need to do to ensure that I in fact do have
