Description Carlos Alberto Lopez Perez 2017-07-12 19:46:15 UTC 
On a new Debian stretch chroot, after installing the packages recommended by the quick install guide:

$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat libsdl1.2-dev xterm

Trying to run bitbake results in this:

$ source poky/oe-init-build-env xtest
-bash: python: command not found
OpenEmbedded requires 'python' to be python v2 (>= 2.7.3), not python v3.
Please upgrade your python v2.


The fix is to install python2 (package name python):

$ sudo apt-get install python

  python-doc python-tk python2.7-doc binfmt-support
The following NEW packages will be installed:

After that bitbake works.

So I think the package named "python" should be added to the list of packages to install in this guide
Comment 1 Scott Rifenbark 2017-07-12 20:09:04 UTC 
So in looking at the section in the Quick Start, the "python" package is part of the list of host packages already.  I am going to list the sections for the 2.4 manual and the 2.3 and 2.3.1 Quick Start manual.  You can see that the "python" package is there. 

What version of the manual or YP were you looking at when you found this issue?

Thanks, 
Scott

2.3 - http://www.yoctoproject.org/docs/2.3/yocto-project-qs/yocto-project-qs.html#packages

2.3.1 - http://www.yoctoproject.org/docs/2.3.1/yocto-project-qs/yocto-project-qs.html#packages

2.4 (under development) - http://www.yoctoproject.org/docs/2.4/yocto-project-qs/yocto-project-qs.html#packages

Thanks, 
Scott

Ups.. I just picked the first result on google that happened to be the doc for 1.8

I think this can be closed as invalid. Sorry for the noise
Comment 3 Scott Rifenbark 2017-07-12 20:45:54 UTC 
No problem..  I am setting to RESOLVED/NOTABUG.  Reset the doc flag as well.
