I have been trying activate a custom module. But i get the following error: 


Unable to install module "stickermanager" because an external dependency is not met: Python library not installed: opcua


Despite rechecking and reconfirming (and also updating to the latest package) that opcua has been installed, i keep getting this error.

Thanks for your reply. I think i didnt explain clearly in my post earlier, "stickermanager" is the name of the module i am developing and the problem is with installing opcua library (external dependency).

Hi, Can you try installing opcua as follows,

For example:

python3 -m pip install opcua

The command show you the details about the installed package

pip show opcua

If it doesn't, then the library might not be installed properly.

In case of multiple versions of Python installed on your system,explicitly specify the version of Python you want to use or or else you can directly install this package from pycharm itself
