Hi, My company is using python embedded into an application. Is it possible to use pylint in unit tests, like the following: from pylint import epylint as lint lint.py_run('../lib/lib.py --rcfile=../pylint.rc') I have tried that one, but I get a strange error: Traceback (most recent call last): File "<string>", line 1, in <module> File "/home/b/development/euryale-module-py/build.debug/py/py_lib/site-packages/pylint/lint/__init__.py", line 76, in <module> from pylint.lint.parallel import check_parallel File "/home/b/development/euryale-module-py/build.debug/py/py_lib/site-packages/pylint/lint/parallel.py", line 8, in <module> from pylint import reporters File "/home/b/development/euryale-module-py/build.debug/py/py_lib/site-packages/pylint/reporters/__init__.py", line 27, in <module> from pylint import utils File "/home/b/development/euryale-module-py/build.debug/py/py_lib/site-packages/pylint/utils/__init__.py", line 47, in <module> from pylint.utils.ast_walker import ASTWalker File "/home/b/development/euryale-module-py/build.debug/py/py_lib/site-packages/pylint/utils/ast_walker.py", line 7, in <module> from astroid import nodes File "/home/b/development/euryale-module-py/build.debug/py/py_lib/site-packages/astroid/__init__.py", line 51, in <module> from astroid.nodes import node_classes, scoped_nodes File "/home/b/development/euryale-module-py/build.debug/py/py_lib/site-packages/astroid/nodes/__init__.py", line 27, in <module> from astroid.nodes.node_classes import ( # pylint: disable=redefined-builtin (Ellipsis) File "/home/b/development/euryale-module-py/build.debug/py/py_lib/site-packages/astroid/nodes/node_classes.py", line 47, in <module> from astroid import decorators, mixins, util File "/home/b/development/euryale-module-py/build.debug/py/py_lib/site-packages/astroid/decorators.py", line 36, in <module> from typing import ParamSpec ImportError: cannot import name 'ParamSpec' from 'typing' (/home/b/development/euryale-module-py/build.debug/py/py_lib/typing.py) After digging a bit, I think that somehow pylint is trying to use *python* executable (from PATH), because my host python is 3.10, while the embedded python is 3.9 and there is no python executable at all. My question is: is there a pylint API to let it check sources with the current python, without doing system/exec etc., which are not available in my case? WBR, basiliscos.
