Fixing Common Issues in Bloomberg API, Angular, and Node.js

Issue 1: Bloomberg API Import Error in Python

If you are trying to use the Bloomberg API with Python and encounter the following error:

ImportError: No module named '_internals'

This typically occurs due to a mismatch between the versions of the Bloomberg C++ SDK and the Python SDK installed on your system. Here’s how you can resolve it:

1. Ensure that you have the latest version of the C++ SDK installed. You can download it from the Bloomberg API Library.
2. After installing, ensure that the path to the SDK’s DLLs (e.g., C:\blp\API\cpp\bin) is added to your system’s PATH environment variable.
3. Restart your Python interpreter or IDE and try importing the blpapi module again.

If you continue to experience issues, double-check that the installed SDK versions match and are compatible.

Issue 2: Angular Schema Validation Error on Windows

While setting up a new Angular project on your Windows machine, you might encounter this error when running ng serve:

Error: Schema validation failed with the following errors:
Data path "" must have required property 'browserTarget'.

This error usually indicates a misconfiguration in your Angular project files. To fix this:

1. Open your angular.json file.
2. Ensure that the serve section has a correctly specified browserTarget property, like this:

"serve": {
    "builder": "@angular-devkit/build-angular:dev-server",
    "options": {
        "browserTarget": "your-project-name:build"
    },
    "configurations": {
        "production": {
            "buildTarget": "your-project-name:build:production"
        },
        "development": {
            "buildTarget": "your-project-name:build:development"
        }
    },
    "defaultConfiguration": "development"
}

1. Replace your-project-name with the actual name of your project.
2. Save the file and try running ng serve again.

This should resolve the schema validation issue.
