安装仅一个Python文件且没有setup.py的软件包

Question

How can i install a python package that does not have a setup.py file to call. I want to install a package that it happens to be only a .py .

Do i just save it as a .py and put it somewhere in the directory and then import it?

For example the zipfile package and the ElementTree XML parser

PS: I have Python-3.x

Answer 1

Edit: As said in the comments, these packages come with Python 3 so you should not install them manually (and certainly not the 2.7 versions). I let my answer bellow for people wanting to install custom package.

On a python interpreter, if you run:

>>> import sys
>>> sys.path

You will see a list of folder where your python executable search for module. You can put your file either in the site-packages folder or the lib folder.

Answer 2

只需将文件放在PYTHONPATH中。
