Python SSL issues, no easy_install or PIP

[drendar]

Hi All,

I'm having a hell of a time trying to get some python modules loaded up - so I've been trying to install PIP.

In order to install pip, I obviously need easy_install (Part of python-setuptools) however this package is missing from the 6.x repo

I followed the instructions at http://forum.tinycorelinux.net/index.php/topic,18781.msg115128.html#msg115128 to download the setuptools package for 5.x and got this installed OK.

The problem I now have is that it seems the python version rolled up into python.tcz doesn't have SSL enabled...

Code: [Select]

tc@box:~$ sudo easy_install pip
Searching for pip
Reading https://pypi.python.org/simple/pip/
Download error on https://pypi.python.org/simple/pip/: unknown url type: https -- Some packages may not be found!
Couldn't find index page for 'pip' (maybe misspelled?)
Scanning index of all packages (this may take a while)
Reading https://pypi.python.org/simple/
Download error on https://pypi.python.org/simple/: unknown url type: https -- Some packages may not be found!
No local packages or download links found for pip
error: Could not find suitable distribution for Requirement.parse('pip')

Searching on this error it's recommended in several places that I need to install openssl-dev and then reinstall python.

So, I've now got installed:

Code: [Select]

openssl
openssl-dev
openssl-1.0.1
openssl-1.0.1-dev
Still no change.

I tried removing and reinstalling the python package, but again that made no difference.

So now I'm stuck, and I have no idea how to progress from here...    Do I need to use an older version of TC, which has the required packages?

Many Thanks in advance.

The openssl-1.0.1 extension was recently updated and renamed to openssl.

If you loaded the updated extension, openssl, you will need to use the apps gui to update your dep files - this will rename openssl-1.0.1 -> openssl in any local dep files containing openssl-1.0.1. After a reboot, you should no longer require openssl-1.0.1 to be loaded.

I sort of doubt that having openssl and openssl-1.0.1 both loaded is causing your problem, but it is worth checking.

[Juanito]

I get the same error as you, so the problem is not having both openssl and openssl-1.0.1 loaded.

Since python-setuptools itself seems to work, it has been copied to the 6.x repo.

In the meantime you could download the pip source code and compile/install it?

[Juanito]

If I compile pip, running it fails with "ImportError: cannot import name HTTPSHandler".

@BMarkus - has python has been compiled without openssl support?

Built with SSL support. Try

Code: [Select]

import ssl

[Juanito]

Hmm - looks like the problem is there:

Code: [Select]

$ python
Python 2.7.10 (default, May 25 2015, 09:55:35)
[GCC 4.9.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import ssl
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/ssl.py", line 97, in <module>
    import _ssl             # if we can't import it, let the error propagate
ImportError: /usr/local/lib/python2.7/lib-dynload/_ssl.so: undefined symbol: SSLv2_method

the latest openssl has sslv2 and sslv3 disabled due to one being broken and the other being a security risk...

[Juanito]

python recompiled and posted, python_pip added.

Things seem to work now...

[Juanito]

python reposted, better optimised for size

[drendar]

Awesome, thanks guys!!

Hey guys,

There looks to be a missing dep (libffi.tcz) on python-setuptools.  This causes both setup_tools and pip to fail.

Removed pip, installed only setuptools, tried to install PIP via setuptools:

Code: [Select]

ImportError: libffi.so.6: cannot open shared object file: No such file or directory

So I loaded libffi along with python_pip again and it's all working!

[Juanito]

As python is compiled to use the system libffi, it's probably more correct to put libffi as a dep of python - dep file adjusted, thanks.

Hi
It seems to me that there is still something that needs fixing.
After updating python and openssl today (plus adjusting .dep files and reboot), I'm not able to use youtube-dl anymore.

Code: [Select]

I just double-checked that I have the latest versions of openssl and python - I do - and everything works fine:

Maybe you used a mirror that hasn't caught up yet?

[Misalf]

I'm using  http://repo.tinycorelinux.net/ .

[Juanito]

I'm surprised that the apps gui "check for updates" function doesn't show that either openssl or python needs updating.

Perhaps you still have openssl-1.0.1 loaded via the dep file of another extension?

If not, then maybe you could try deleting your local copies of openssl and python and downloading them again with the apps gui?
