Troubleshooting when installing MBsysPy

For this issue, we consider that you did not manage to install the MBsysPy module with the pip command in Spyder but you manage to install it using your system terminal. Please keep this terminal open !

When coming back into the Spyder console, try to type import MBsysPy. If ModuleNotFoundError: No module named 'MBsysPy' is returned, it means that the pip command installed the module MBsysPy in a Python path not browsed by Spyder. To add this Python path to Spyder, you first need to locate the MBsysPy module installed by pip. In your Terminal console, type pip show MBsysPy and copy the location referred here after as your pip path your_pip_path_for_MBsysPy. In Spyder, select Python Path Manager (last item on the right of the tool band with the Python logo). Click on Add path and select the path referred by your Terminal. If you are not able to select the Python path containing the MBsysPy module, open the hidden file .bashprofile in your ~/home repositery and add /export PYTHONPATH=$PYTHONPATH:/your_pip_path_for_MBsysPy at the bottom of the file. Save the file and close it. Relaunch Spyder and type ìmport MBsysPy into the console. If the module is still not found, please send an email to support@robotran.be with the specifications of your OS and Python version.

Permission error raised when running main.py in Spyder under MacOS Catalina 10.15

When running a Robotran project (main.py) with a Spyder console under MacOS Catalina 10.15, you might obtain the following error I/O error : Operation not permitted. The explanation is: Spyder is not able to access the files you want to run due to a higher level of security imposed by macOS Catalina on /Desktop, /Document and /Downloads repositeries. This access restriction is even more highlighted when running a Robotran project as Robotran is built following a tree structure using different folders (dataR, userfctR, workR, etc.) that Spyder cannot access anymore. However, running the Python code into an system terminal allows you to run your code normally. If your Spyder version is 4.0.0 or after, you may directly launch your code into an external system terminal (Spyder>Run>Configuration per file...). If your Spyder version is older than 4.0.0, open a terminal console, go into your project location /Your_MBS_Project/workR/ and launch the Python code with the commmand python main.py.
