error: "No module named pyvisa_py"… | Apple Developer Forums

error: "No module named pyvisa_py" in Xcode. This error doesn't happen running the command directly in terminal.

IDE: Xcode

I have the following code in my program sending this command in terminal. Program hangs up on this line and the debug area shows error "no module named pyvisa_py".

(power_max.py import the pyvisa module)

Then I try this command in terminal directly and the module pyvisa_py, installed already, can be found. The python file can be executed successfully.

How could I make Xcode identify the pyvisa_py module?

    [cmd appendString:@“python3 /Users/shared/power_max.py”];

    [cmd appendString:[Paremeter_IP stringValue]];

    [cmd appendString:@" > /users/Shared/CMW.txt"];

    system([cmd UTF8String]);
