reactjs - How to resolve the error on 'react-native start'

Question

1. I just installed node.js & cli

   • installed node.js

   • installed react-native-cli

     npm -g react-native-cli
     

2. And created a 'new project'.

   react-native init new_project
   

3. and inside that 'new_project' directory, I tired to see if metro bundler works well.

   react-native start
   

4. But the command gave me following error and metro is not starting. Any clue for fixing this error? (I'm using windows 10 OS.)

   • command : C:projects ew_proj>react-native start

Answer 1

I just got a similar error for the first time today. It appears in ode_modulesmetro-configsrcdefaultslacklist.js, there is an invalid regular expression that needed changed. I changed the first expression under sharedBlacklist from:

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

to:

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