Pylint fails with "ImportError: cannot import name 'version'"

[musabhusaini]

Running pylint 2.3 on any set of files fails. This issue is fixed if astroid 2.5.3 is explicitly installed.

Steps to reproduce

Run pylint 2.3 on any set of files.

Current behavior

This error is received:

Traceback (most recent call last):
  File "/usr/local/bin/pylint", line 8, in <module>
    sys.exit(run_pylint())
  File "/usr/local/lib/python3.6/site-packages/pylint/__init__.py", line 17, in run_pylint
    from pylint.lint import Run
  File "/usr/local/lib/python3.6/site-packages/pylint/lint.py", line 77, in <module>
    from astroid.__pkginfo__ import version as astroid_version
ImportError: cannot import name 'version'

This is part of our CI checks and we just started getting this error a few hours ago.

Expected behavior

Linting should proceed without runtime errors.

pylint --version output

Result of pylint --version output:

Traceback (most recent call last):
  File "/usr/local/bin/pylint", line 8, in <module>
    sys.exit(run_pylint())
  File "/usr/local/lib/python3.6/site-packages/pylint/__init__.py", line 17, in run_pylint

Thank you for the report, it's going to be fixed in astroid 2.5.6.
