The token '&&' is not a valid statement separator in this version

问题

On the way of installing Webpack on my React Project, the following problem hinders my progress:

last step to configure the Webpack

npm run build && node ./dist/main.js

Error on Windows Power Shell / on Visual Studio Code

PS C:\Users\pythonbuddha\Desktop\to_experiment\to-do-list> npm run build && node ./dist/main.js
At line:1 char:15

回答1:

It's because you're in PowerShell, try running it in CMD or Git Bash

Alternatively (if you wish to continue in PS):

(npm run build) -and (node ./dist/main.js)

3rd Alternative, just run them separetly,

回答2:

The && operator is used in linux bash to run both commands after each other. (Also if the first command fails, the second won't be executed)

This does not work in PowerShell on Windows so just split both commands and run them separately:

npm run build
node ./dist/main.js

For completeness, Powershell can behave the same when you do (command1) -and (command2) and && might actually work depending on your PowerShell version.

simply run the two commands separately:
