install method

@override Future<void> install(Version version, { required CommandLogger logger, })

Installs exactly version of the CLI.

Throws a CliUpdateFailedException if the install could not be run or did not succeed.

Implementation

@override
Future<void> install(
  final Version version, {
  required final CommandLogger logger,
}) async {
  final arguments = installArguments(installation, version: version);
  logger.debug('Installing $_cliPackageName $version: $arguments');

  final ProcessResult result;
  try {
    result = await Process.run(_dartExecutable, arguments);
  } on ProcessException catch (e, stackTrace) {
    logger.debug('Failed to run the install command: $e\n$stackTrace');
    throw CliUpdateFailedException(
      version: version,
      reason: 'the install command could not be run: ${e.message}',
    );
  }

  if (result.exitCode != 0) {
    logger.debug(
      'The install command exited with ${result.exitCode}.\n'
      '${result.stdout}\n${result.stderr}',
    );
    throw CliUpdateFailedException(
      version: version,
      reason: 'the install command exited with ${result.exitCode}',
    );
  }
}
