Why doesn't the Expo emulator start?

Question

JavaScript

Good afternoon!
If you're familiar with the Expo CLI NPM tool, have you encountered this kind of error after running the expo start ? command:

$ cd client && expo start
Starting project at /home/head/Рабочий стол/WCCApps/client

Unable to find expo in this project - have you run yarn / npm install yet?
    ├─ action /usr/local/lib/node_modules/expo-cli/src/commands/start.ts:34:11
    ├─ /usr/local/lib/node_modules/expo-cli/src/commands/start.ts:135:22
    └─ expo start /usr/local/lib/node_modules/expo-cli/src/exp.ts:350:7

But the expo init client ran 100% without issue when bundled with the React Native install!

What does this mean and how can I fix it so I can run the Expo emulator normally?

Parameters for the question base:

• OS: Linux Ubuntu 18.04
  
• NPM version: 7.13.0
  
• Expo version: 4.4.7
  

Answer 1

It looks like the Expo CLI is simply not installed. Trynpm install -g expo-cli
