How do I install pip on ubuntu?

[tzachshabtay]

Hi, downloaded the zip file from release 2.7.8. I'm trying to install pip for IronPython on ubuntu 16.04 LTS 64 bits.

Tried the dotnet core runtime first with bash netcoreapp2.0/ipy.sh -X Frames -m ensurepip and got:

Unhandled exception:
Traceback (most recent call last):
  File "/home/tshabtay/Downloads/IronPython/Lib/runpy.py", line 187, in run_module

  File "/home/tshabtay/Downloads/IronPython/Lib/ctypes/__init__.py", line 7, in <module>
ImportError: No module named _ctypes

That's after I've set IRONPYTHONPATH to point at Lib.

Then I tried mono with net40 with mono net40/ipy.exe -X Frames -m ensurepip and got:

Unhandled exception:
Traceback (most recent call last):
TypeError: Value cannot be null.
Parameter name: method

Finally I tried mono with net45 with mono net44/ipy.exe -X Frames -m ensurepip and got:

Traceback (most recent call last):
  File "/home/tshabtay/Downloads/IronPython/Lib/logging/__init__.py", line 861, in emit

    if hasattr(real_stream, "isatty") and real_stream.isatty():
SystemError: GetStdHandle

Can any of those be made to work? Thanks.

This has not been tested at all, so you are breaking new ground. The net45 is a known issue (I think there is already an issue filed for it). net40 is going to be removed soon, so don't spend any time on that. For the .NET Core, it looks like _ctypes is required, I thought we had that for .NET Core though, so I don't know why its failing like that.

@slide No support for ctypes on .NET Core at the moment. I don't remember what was the blocking factor...

[slide]

@slozier did some nice work in #365 to get ctypes working with .net core.

I tried with the latest bits and am still getting some issues. With Mono:

Exception:

With .NET Core it works the first time around, however the files are ending up in an odd location: /mnt/c/IronPython.2.7.9-candidate1/Lib/python2.7/site-packages. Also, if I try to install again I get an error:

Traceback (most recent call last):

The exceptions above have been resolved, however there are more issues to figure out, for example:

• Mono: ensurepip install folder is odd so pip isn't picked up after install
• .NET Core: how to make Mono.Posix.Netstandard available?

[slozier]

Looks like the install folder is from in setuptools (easy_install.py):

    INSTALL_SCHEMES = dict(
        posix=dict(
            install_dir='$base/lib/python$py_version_short/site-packages',
            script_dir='$base/bin',
        ),
    )

Is there any update on closing this issue?

It looks as if this is the only issue holding up the 2.7.9 release.

There is still a fair amount of work that needs to be done here, I think we might remove this from the 2.7.9 milestone.

[slozier]

I think it was somewhat working with the latest bits (at least the Mono version). I will have to try it again to double check.
