$ npm run devserver is not working

[ipyana]

Unfortunately am getting these errors when cloned the project and follow all the steps on setting environment for Node and its dependencies.

[saleh-dot]

you have to kill port and then restart you can do this in command prompt or using same terminal first have to change directory to /c

[saleh-dot]

netstat -ano | findstr :3000 this will give you PID 4 digit number at end

[saleh-dot]

taskkill /PID "PID" /F "PID" will be from "netstat -ano | findstr :3000"

I am also having similar problem, having cloned the repo, it doesn't display on web browser when I type in log as shown in the video tutorial

For those having issues making this work, try this. First I downloaded Git and ran Git Bash. If you don't gitbash follow this tutorial https://www.youtube.com/watch?v=BMW7LiF_Oc4 I created a folder "code" on C:// With the Git Bash terminal I navigated (type in cd /c/code/ ) to the directory I wanted to install the data to. Then type in the following: git clone https://github.com/amigoscode/javascript.git cd javascript/ try running these in order:

npm install npm cache clean --force npm install -g npm npm install *optional (npm unistall ~/.node-gyp then npm update) npm run devserver

I hope this helps

1. Remove the node_modules complete folder and remove the package-lock.json file

2. Clear npm cache by using command npm cache clean. you can force to clean if gives error

3. Install and then rebuild node-sass

npm install node-sass@latest npm rebuild node-sass

4. npm i

This worked for me

Didn't need to remove anything. Just do:

npm install node-sass@latest npm rebuild node-sass npm i

It worked for me
