> demo@0.0.1 start D:\VueNative\demo
> node node_modules/react-native/local-cli/cli.js start

error Invalid regular expression: /(.*\\__fixtures__\\.*|node_modules[\\\]react[
\\\]dist[\\\].*|website\\node_modules\\.*|heapCapture\\bundle\.js|.*\\__tests__\
\.*)$/: Unterminated character class. Run CLI with --verbose flag for more detai

NodeJS version: v14.7.0

Solution: Edit file node_modules\metro-config\src\defaults\blacklist.js

Line 14-19

var sharedBlacklist = [
  /node_modules[/\\]react[/\\]dist[/\\].*/,
  /website\/node_modules\/.*/,
  /heapCapture\/bundle\.js/,
  /.*\/__tests__\/.*/
];

Change to:

var sharedBlacklist = [
  /node_modules[\/\\]react[\/\\]dist[\/\\].*/,
  /website\/node_modules\/.*/,
  /heapCapture\/bundle\.js/,
  /.*\/__tests__\/.*/
];

Done
