python cant be found

[jambo dev]

Hi,

I'm trying to install sagemath from source, I know I have python3 installed. The binary is in /usr/bin/python3. Here is what I do:

./configure

and then

make

I get this message:

/usr/bin/env: ‘python’: No such file or directory

make: *** [Makefile:31: base-toolchain] Error 127

I appreciate your help

We need a bit more information. Which version of Sage are you trying to install? Post config.log 

[jambodev]

Hi Matthias,

Thanks for your reply.

I'm trying to install 9.2 from source.

Please find my config.log attached.

[Matthias Koeppe]

According to config.log, the build is not using system python but rather the Sage distribution's own copy of python3 -- which was installed before the run of configure that is shown in this config.log

This command:

$ ls -l local/bin/python*

should show a symlink python->python3.

Also, please post logs/install.log

Or start with a fresh install of the current beta version.

Thanks Matthia for looking into this and for your reply.

However, I must say that I, in the first instance thought about having that symlink and I searched and I found this on that:

•    Or start with a fresh install of the current beta version.  

does that mean that the current beta version would have this issue? If so I will use that.

Regards,
