[FIXED] No Spyder-Terminal on Spyder 5.0.5 (MacOS)

Issue

I tried to install spyder terminal on my spyder.

Steps oI followed (in iPython Console):

!conda install -c conda-forge spyder-terminal

Then:

import spyder_terminal

And I get an error message that says:

No QCoreApplication instance found. Application patches not applied. You have to call load_stylesheet function after instantiation of QApplication to take effect. 
Traceback (most recent call last):

  File "<ipython-input-2-fb5605fc26a6>", line 1, in <module>
    import spyder_terminal

  File "/opt/anaconda3/lib/python3.8/site-packages/spyder_terminal/__init__.py", line 10, in <module>
    from .terminalplugin import TerminalPlugin as PLUGIN_CLASS

  File "/opt/anaconda3/lib/python3.8/site-packages/spyder_terminal/terminalplugin.py", line 17, in <module>
    from spyder.api.plugin_registration.decorators import on_plugin_available

ModuleNotFoundError: No module named 'spyder.api.plugin_registration'

I thought that it was because of the enviroment, so I tried to create a new conda enviroment with the spyder terminal module. I do as follows (in my terminal):

conda create -n spyder-env -y

Then:

conda activate spyder-env

And finally:

conda install spyder-kernels spyder-terminal -y

And I get an error that says:

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

Any idea what could I do to get the spyder terminal?

Specs:

• Spyder 5.0.5
• Anaconda 2.0.4
• MacOS Big Sur 11.4

Solution

Spyder-terminal hasn't been updated to work with spyder 5.0.5, yet. See here:
