Jupyter Kernel Error (Installation using Old Method 2)

[MarsSongco]

I tried installing Maxima-Jupyter using old method 2 (Maxima-Jupyter loadable source installation) and I got this message indicating that I have installed maxima-jupyter successfully.

However, opening jupyter notebook and choosing maxima as the kernel gives out a kernel error like this:

The whole error log reads: Traceback (most recent call last): File "C:\Python39\lib\site-packages\tornado\web.py", line 1704, in _execute result = await result File "C:\Python39\lib\site-packages\tornado\gen.py", line 769, in run yielded = self.gen.throw(*exc_info) # type: ignore File "C:\Python39\lib\site-packages\notebook\services\sessions\handlers.py", line 69, in post model = yield maybe_future( File "C:\Python39\lib\site-packages\tornado\gen.py", line 762, in run value = future.result() File "C:\Python39\lib\site-packages\tornado\gen.py", line 769, in run yielded = self.gen.throw(*exc_info) # type: ignore File "C:\Python39\lib\site-packages\notebook\services\sessions\sessionmanager.py", line 88, in create_session kernel_id = yield self.start_kernel_for_session(session_id, path, name, type, kernel_name) File "C:\Python39\lib\site-packages\tornado\gen.py", line 762, in run value = future.result() File "C:\Python39\lib\site-packages\tornado\gen.py", line 769, in run yielded = self.gen.throw(*exc_info) # type: ignore File "C:\Python39\lib\site-packages\notebook\services\sessions\sessionmanager.py", line 100, in start_kernel_for_session kernel_id = yield maybe_future( File "C:\Python39\lib\site-packages\tornado\gen.py", line 762, in run value = future.result() File "C:\Python39\lib\site-packages\notebook\services\kernels\kernelmanager.py", line 176, in start_kernel kernel_id = await maybe_future(self.pinned_superclass.start_kernel(self, **kwargs)) File "C:\Python39\lib\site-packages\jupyter_client\multikernelmanager.py", line 185, in start_kernel km.start_kernel(**kwargs) File "C:\Python39\lib\site-packages\jupyter_client\manager.py", line 313, in start_kernel self.kernel = self._launch_kernel(kernel_cmd, **kw) File "C:\Python39\lib\site-packages\jupyter_client\manager.py", line 222, in _launch_kernel return launch_kernel(kernel_cmd, **kw) File "C:\Python39\lib\site-packages\jupyter_client\launcher.py", line 134, in launch_kernel proc = Popen(cmd, **kwargs) File "C:\Python39\lib\subprocess.py", line 947, in __init__ self._execute_child(args, executable, preexec_fn, close_fds, File "C:\Python39\lib\subprocess.py", line 1416, in _execute_child hp, ht, pid, tid = _winapi.CreateProcess(executable, args, FileNotFoundError: [WinError 2] The system cannot find the file specified

Is this an indication of a wrong path setting or is this an indication of an error somewhere in my installation process? Thank you!

If you are using Windows the installation is more difficult because of the cffi and static-vectors dependency in common-lisp-jupyter. I would go try to get common-lisp-jupyter working first. Also, I haven't used the old installation method for a very long time.
