如何在没有必需的外部库模块的其他系统上运行Python代码？

Question

I have built a Python application using an external library (lxml-module). This runs fine in my system. Is there any way to compile this code or package this code, so that I can run it in another system which does not have this external library (lxml-module) module installed in it?

If possible please give me a little reference on *.pyd also?

Answer 1

PyInstaller would be a good way to go to package your code.

It works in a configure/make/build workflow (before which you setup a small spec file with different kinds of options). The external package will be shipped along with your application.

lxml is supported in PyInstaller: http://www.pyinstaller.org/wiki/SupportedPackages .

As for being able to compile your code on another machine, Marcin had a good suggestion.

Answer 2

You can always copy the module to your local path and import it from there. Kind of what django did for json until it was included in the standard library.

This could do the trick:

try:
    import lxml
except ImportError:
    import myownmodules.lxml as lxml

I know this is the less "high tech" approach but if the problem is simple enough this is what I would do without a blink.

Besides .... our buddy Tim seems to agree: "If the implementation is easy to explain, it may be a good idea."

对于Windows使用py2exe打包，对于OSX使用py2app ，对于Linux使用cx_freeze
