 |
|
| I have python 3.2.3 installed and I'd like to have python 2.7. However, I can't seem to find the right reference for convincing emerge to do that for me. Sorry, this is very basic, but I need a pointer. |

| Code: | | emerge =dev-lang/python-2.7.3-r3 |
The Working with gentoo and Working with portage parts of the handbook are recommended reading.

roundtuit ...
alternately, you can stipulate the 'slot' like so:
| Code: | | # emerge -a python:2.7 |
or ... use a wildcard (so that any keyworded version is applicable)
| Code: | | # emerge -a =dev-lang/python-2* |
best ... khay |

Thanks, I used that last one (once I got past my emerge portage failing with bash-4.2 after I did a sync [1] - had to manually build bash 4.1 and temporarily put in in place of bash 4.2 at /bin/bash). The python-2* emerge worked well (esp. when you don't know exactly which 2* flavor it is - although I haven't yet found the right way to list what possible version is available)
Then (for the sake of others reading this thread later) I did 'eselect python set python2.7' ("python2", "python2*" didn't work - there's probably a way) to make python2 (currently 2.7.3) the default.
[1] I gather one is supposed to emerge portage first, then emerge --sync. |

roundtuit ... not sure I understand what happened with bash, or why that might happen. Anyhow, getting version information: 'eshowkey' (app-portage/gentoolkit).
| Code: | # eshowkey python
Keywords for dev-lang/python:

Thats right, becuase 'python2*' might match more than one target, and so the version must be explicit. You can also use the numeric tags:
| Code: | # eselect python list
Available Python interpreters:
[1] python2.7 *
[2] python3.2
# eselect python set 1 |
