Lines 95 to 123 in 9c740b9

	export function getEnvironmentTypeName(environmentType: EnvironmentType): string {
	switch (environmentType) {
	case EnvironmentType.Conda: {
	return 'conda';
	}
	case EnvironmentType.Pipenv: {
	return 'pipenv';
	}
	case EnvironmentType.Pyenv: {
	return 'pyenv';
	}
	case EnvironmentType.Venv: {
	return 'venv';
	}
	case EnvironmentType.VirtualEnv: {
	return 'virtualenv';
	}
	case EnvironmentType.MicrosoftStore: {
	return 'microsoft store';
	}
	case EnvironmentType.Poetry: {
	return 'poetry';
	}
	case EnvironmentType.VirtualEnvWrapper: {
	return 'virtualenvwrapper';
	}
	case EnvironmentType.ActiveState: {
	return 'activestate';
	}

FYI we do this to make it consistent with all the tools. cc/ @luabud @cwebster-99

@karrtikr I think we should make it look the way each tool (owner) wants it to appear.
