1. A virtual environment isn't going to happen in this context because it would totally break the entire robot ecosystem.
Then the program has a design flaw.
Usually, a program uses the Python standard libraries, 3rd party libraries (Packages and Modules) and own library code.
The own code does not have to be a PyPI package.
But you can still add additional search paths to sys.path.
This is not required, if the project has already the right directory structure.
e.G. if you run a main.py or something else, this path is added automatically to sys.path, which is used to find modules. Modules are just python-files.
Output:
Structure:C:\Users\XXX\TestProg>py main.py
Hello from main.py
Trying to import foo
foo module not found
Adding directory to sys.path
Hello from foo
Code:
│ main.py│└───my_lib └ foo.py Code:
print("Hello from main.py")print("Trying to import foo")try: import fooexcept ImportError: print("foo module not found")print("Adding directory to sys.path")import syssys.path.append("my_lib")import fooCode:
print("Hello from foo")You can also use the full qualified path of the module:
Code:
print("Hello from main.py")print("Importing foo")import my_lib.foo# my_lib is a NameSpaceprint(my_lib)But without knowing the structure, it's hard to say which takes lesser effort.
