I have installed CLIPSpy from the git repository, and followed the instructions for installing with the source files. Yet after installing and running the python shell I get this error:
`import clips
.../clipspy/clips/__init__.py", line 30, in <module>
from clips.error import CLIPSError
.../clipspy/clips/error.py", line 32, in <module>
from clips.router import Router
.../clipspy/clips/router.py", line 7, in <module>
from clips._clips import lib, ffi
ModuleNotFoundError: No module named 'clips._clips'`
Despite this error, if I run the same commands outside of my CLIPSpy directory, I can import clips but get a different error.
>>> import clips
>>> env = clips.Environment()
>>> env.assert_string("(test 12)")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'Environment' object has no attribute 'assert_string'
My assumption is that ModuleNotFoundError may be responsible for the AttributeError.
OS: Arch Linux
git-repo: https://github.com/noxdafox/clipspy
I followed the advice of specifying the directory of clips, using pyclips and import clips as a python module, to specify the location of clips but it still gives me the same error.
Installing CLIPSpy via pip gave 'satisfactory' results: ModuleNotFoundError: No module named 'pygame'
Requirement already satisfied: clipspy in /usr/lib/python3.7/site-packages/clipspy-0.3.2_2_g7dd9ca2-py3.7-linux-x86_64.egg (0.3.2-2-g7dd9ca2)
Requirement already satisfied: cffi>=1.0.0 in /usr/lib/python3.7/site-packages (from clipspy) (1.12.2)
Requirement already satisfied: pycparser in /usr/lib/python3.7/site-packages (from cffi>=1.0.0->clipspy) (2.19)
I tried re-installing clipspy via github many times, but the same issue persists. The interesting part is that I used pyclips as alternative for a while and it gave me the same error. It might be something to do with the directory or the installation, but I am not sure what it could be.
The installation process for CLIPSpy was as follows:
make:
python setup.py build_ext --include-dirs clips_source \
--library-dirs clips_source
/usr/lib/python3.7/site-packages/setuptools/dist.py:484: UserWarning: The version specified ('0.3.2-2-g7dd9ca2') is an invalid version, this may not work as expected with newer versions of setuptools, pip, and PyPI. Please see PEP 440 for more details.
"details." % self.metadata.version
running build_ext
generating cffi module 'build/temp.linux-x86_64-3.7/_clips.c'
already up-to-date
I tried re-installing setuptools to see if I could get a valid dist.py version, but alas nothing has changed.
sudo make install:
....

The solution could be something simple, but I can't seem to know what it is.
Any help or advice on what to do or where I went wrong would be greatly appreciated.
EDIT 1: After removing files related to clips, and having a fresh install, I no longer receive the Atribute Error. Rather I get an ImportError
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.7/site-packages/clipspy-0.3.1-py3.7-linux-x86_64.egg/clips/__init.py", line 30, in <module> from clips.error import CLIPSError

Import Error: libclips.so: cannot open shared object file: No such file or directory
I've cloned the git repository that contains tag 3.2
EDIT 2: Managed to fix the error by renaming the libclips.so.6 file located in the /usr/lib/ folder to libclips.so Now it works.
I am the author of the clipspy module. I would rather suggest you to open a GitHub issue for these types of matters rather than a SO question.
As a general line, the issues you are suffering from indicate you are trying to install a Python module in a dirty environment. For example, installing via pip resolves in a noop because you ran make install beforehand and pip sees the package is already installed.
To install from git, you either git clone a specific tag or download the code from a specific release. clipspy uses tags to infer the version numbers hence you see the warning:
UserWarning: The version specified ('0.3.2-2-g7dd9ca2') is an invalid version, this may not work as expected with newer versions of setuptools, pip, and PyPI. Please see PEP 440 for more details.
A common issue when installing clipspy is an old version of setuptools. Have you tried updating it to a more recent version?
# pip install --upgrade setuptools
One last note, do you happen to also have PyCLIPS installed within the system? The namespaces will conflict as the modules are both called clips. This would explain the error traceback:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'Environment' object has no attribute 'assert_string'
