Python scripts installed as part of the Pylons install process will be put in the Scripts directory of your Python installation, typically in C:\Python24\Scripts. By default on Windows, this directory is not in your PATH; this can cause the following error message when running a command such as paster from the command prompt:
1
2
3 | C:\Documents and Settings\James>paster
'paster' is not recognized as an internal or external command,
operable program or batch file.
|
To run the scripts installed with Pylons either the full path must be specified:
1
2
3
4
5
6
7
8
9
10
11 | C:\Documents and Settings\James>C:\Python24\Scripts\paster
Usage: C:\Python24\Scripts\paster-script.py COMMAND
usage: paster-script.py [paster_options] COMMAND [command_options]
options:
--version show program's version number and exit
--plugin=PLUGINS Add a plugin to the list of commands (plugins are Egg
specs; will also require() the Egg)
-h, --help Show this help message
... etc ...
|
or (the preferable solution) the Scripts directory must be added to the PATH as described below.
- From the desktop or Start Menu, right click My Computer and click Properties.
- In the System Properties window, click on the Advanced tab.
- In the Advanced section, click the Environment Variables button.
- Finally, in the Environment Variables window, highlight the path variable in the Systems Variable section and click edit. Add or modify the path lines with the paths you wish the computer to access. Each different directory is separated with a semicolon as shown below:
1 | C:\Program Files;C:\WINDOWS;C:\WINDOWS\System32
|
- Add the path to your scripts directory:
1 | C:\Program Files;C:\WINDOWS;C:\WINDOWS\System32;C:\Python24\Scripts
|
See Finally below.
Edit autoexec.bat, and add the following line to the end of the file:
1 | set PATH=%PATH%;C:\Python24\Scripts
|
See Finally below.
Restarting your computer may be required to enable the change to the PATH. Then commands may be entered from any location:
1
2
3
4
5
6
7
8
9
10
11 | C:\Documents and Settings\James>paster
Usage: C:\Python24\Scripts\paster-script.py COMMAND
usage: paster-script.py [paster_options] COMMAND [command_options]
options:
--version show program's version number and exit
--plugin=PLUGINS Add a plugin to the list of commands (plugins are Egg
specs; will also require() the Egg)
-h, --help Show this help message
... etc ...
|
All documentation assumes the PATH is setup correctly as described above.

Note to others - you can't run any of the paste commands in a non-admin account on Windows.
