[Tutor] Help installing Python3 in a particular folder

[Alan]

Hi there,

I am doing this:

cd /temp
wget -c http://www.python.org/ftp/python/3.3.2/Python-3.3.2.tar.xz
tar xvf Python-3.3.2.tar.xz
cd Python-3.3.2
./configure --prefix=/sw/arch
make
make test
make install

Then, when I try:

/sw/arch/bin/python3

               Traceback (most recent call last):
  File "/sw/arch/lib/python3.3/site.py", line 69, in <module>
    import os
  File "/sw/arch/lib/python3.3/os.py", line 659, in <module>
    from collections.abc import MutableMapping
  File "/sw/arch/lib/python3.3/collections/__init__.py", line 12, in
<module>
    from keyword import iskeyword as _iskeyword
ImportError: No module named 'keyword'

But if I do:

export PYTHONPATH=/temp/Python-3.3.2/Lib

then python3 will work.

However, this does seems correct for me. I shouldn't depend on the
installation folder (which I want to delete btw).

I compared

/sw/arch/lib/python3.3/ X /temp/Python-3.3.2/Lib

and found this files missing:

Only in /temp/Python-3.3.2/Lib: base64.py
Only in /temp/Python-3.3.2/Lib: cgi.py
Only in /temp/Python-3.3.2/Lib: cProfile.py
Only in /temp/Python-3.3.2/Lib: keyword.py
Only in /temp/Python-3.3.2/Lib: msilib
Only in /temp/Python-3.3.2/Lib: pdb.py
Only in /temp/Python-3.3.2/Lib: plat-aix4
Only in /temp/Python-3.3.2/Lib: plat-darwin
Only in /temp/Python-3.3.2/Lib: platform.py
Only in /temp/Python-3.3.2/Lib: plat-freebsd4

Only in /temp/Python-3.3.2/Lib: plat-unixware7
Only in /temp/Python-3.3.2/Lib: profile.py
Only in /temp/Python-3.3.2/Lib: pydoc.py
Only in /temp/Python-3.3.2/Lib: quopri.py
Only in /temp/Python-3.3.2/Lib: smtpd.py
Only in /temp/Python-3.3.2/Lib: symbol.py
Only in /temp/Python-3.3.2/Lib: tabnanny.py
Only in /temp/Python-3.3.2/Lib: token.py
Only in /temp/Python-3.3.2/Lib: uu.py

During "make install" I noticed this:

/sw/arch/lib/python3.3 already exist, returning without doing anything
arguments where -c ./Lib/keyword.py /sw/arch/lib/python3.3
/sw/arch/bin/install -c ./Lib/keyword.py /sw/arch/lib/python3.3

So, apparently keyword.py should have been copied into
/sw/arch/lib/python3.3 but it's really not happening.

What am I doing wrong here?

Thanks,

Alan
