Can you post the output of env python -V?

D'oh, it was still pointing to 2.4.x, fixed that then ran into this when running make:

That was fixed in joyent/libuv@d5b2615. It's not back-ported to Node yet (might not happen until v0.8) but you can cherry-pick the commit if you want.

@oreoshake - you said "D'oh, it was still pointing to 2.4.x, fixed that then ran into this when running make:"

Do you mean you were pointing to your Python install of 2.4.x? If so, how did you change that? I think I have the same problem. Thanks

@gyrospike: Set the PYTHONPATH and PYTHONHOME environment variables before you run make.

[jalleyne]

I'm having the same problem with make. I added alias and set PYTHONPATH and PYTHONHOME so now if i run which python i get the correct version along with python -version but env python -V still points to 2.4. any thoughts?

[bnoordhuis]

@jalleyne: Try this:

$ export PYTHON=/path/to/good/python
$ $PYTHON configure
$ make PYTHON=$PYTHON

[jalleyne]

@bnoordhuis: thanks allot...

now i get this on $PYTHON configure

With what version of python is this? 2.5 might work but 2.6 or 2.7 is recommended. 3.x is not supported.

[jalleyne]

I should have realized this but i was using the latest version from the repository and its not stable :(.. my fault completely.. i checkedout the same version as i did for my local dev (0.6.12) and its working now. thanks for the help.

[jalleyne]

@bnoordhuis: it was 2.6 with the latest from repo at about 2pm this afternoon. in retrospect i believe that version was marked as unstable so that might explain the syntax errors.
