| 53 | 2.8 Debugging the setup script</A> |
| 54 | </H1> |
| 55 | |
| 56 | <P> |
| 57 | Sometimes things go wrong, and the setup script doesn't do what the |
| 58 | developer wants. |
| 59 | |
| 60 | <P> |
| 61 | Distutils catches any exceptions when running the setup script, and |
| 62 | print a simple error message before the script is terminated. The |
| 63 | motivation for this behaviour is to not confuse administrators who |
| 64 | don't know much about Python and are trying to install a package. If |
| 65 | they get a big long traceback from deep inside the guts of Distutils, |
| 66 | they may think the package or the Python installation is broken |
| 67 | because they don't read all the way down to the bottom and see that |
| 68 | it's a permission problem. |
| 69 | |
| 70 | <P> |
| 71 | On the other hand, this doesn't help the developer to find the cause |
| 72 | of the failure. For this purpose, the DISTUTILS_DEBUG environment |
| 73 | variable can be set to anything except an empty string, and distutils |
| 74 | will now print detailed information what it is doing, and prints the |
| 75 | full traceback in case an exception occurs. |
| 76 | |
