- You will need wget, which is not present. So from here wget is simply curl -O. However there are a bunch of problems with making wget an alias to curl -O from aliases not being expanded in noninteractive shells to some debate about what /bin/sh does on mac. My pragmatic solution was
- make a one line script curl -O "$@" and save it as /usr/bin/wget and chmod +x for that file
- Then proceed with make which should conclude successfully
Python's context managers are a very neat way of handling code that needs a teardown once you are done. Python objects have do have a destructor method ( __del__ ) called right before the last instance of the object is about to be destroyed. You can do a teardown there. However there is a lot of fine print to the __del__ method. A cleaner way of doing tear-downs is through Python's context manager , manifested as the with keyword. class CrushMe: def __init__(self): self.f = open('test.txt', 'w') def foo(self, a, b): self.f.write(str(a - b)) def __enter__(self): return self def __exit__(self, exc_type, exc_val, exc_tb): self.f.close() return True with CrushMe() as c: c.foo(2, 3) One thing that is important, and that got me just now, is error handling. I made the mistake of ignoring all those 'junk' arguments ( exc_type, exc_val, exc_tb ). I just skimmed the docs and what popped out is that you need to return True or...
