EDIT: I am having this issue again :/

[kalinchernev]

I also got error with chokidar and this error code migrating from a hugo site with nested folders in static after forestry handles assets like this.
The linux-specific command for fs worked.

[shivamlekhi]

For what it's worth, I ran npm install npm update and it works again.

[OmarJaber]

I have The same error !!

[KyleAMathews]

Closing older issues, please open new issues if you need more help!

[hemnathmouli]

Your site is running at http://localhost:8000
Try changing your port. Like 3000 or 8080.

app.listen(3000)

My 8080 post was taken, so I got this same error

What is this error?!

[juliancorrea]

In my MAC, I ran "killall node" and "yarn start" (or npm start) and everything is fine now.

[AliZeynalov]

@juliancorrea thanks man. executing killall node solved my problem, as well

All you have to do is close all other open terminals.

Also in my case I had working through Intellij, and when ever I closed the terminal, i had to make my way back to the folder with the js file.

[henriqueslaporta]

This fix for me:

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

Source: Node.JS Error: ENOSPC

[kw3ku]

if you are on node project, kindly change the port number. if it was port Listen="3004", make it port listing ="3005"

[kapomaho]

After closed the Intellij idea my problem solved.

[rmsparajuli]

i got this error , Please help me.

[ArunEdathadan]

Check this ,solved mine https://stackoverflow.com/questions/43931986/how-to-upgrade-angular-cli-to-the-latest-version

[jpbbrito]

@kw3ku be right, in my case used port 80 i changed to 3000 it running normally now.

[Jiunsr]

@kw3ku be right, in my case used port 80 i changed to 3000 it running normally now.

Right！My project port number changed to 3200 just fine. Previously number 9080.

[AkankS19]

i got this error , Please help me.

I am getting the same issue. Did you get any fix for this ?

[satyendrakannaujiya]

This fix for me:

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

Source: Node.JS Error: ENOSPC
it works for me also

[mdmasumbillah]

Run killall node
and start your app

[MarcusWiilo]

Just change the door, in my case change to 8080 and function

[garrettbear]

I've run into this issue a handful of times and it always leads to something is running on that port. So just make sure to kill the PID running on that port

Find the PID:
lsof -i :3000

Kill:
kill -9 <PID>

[sengbh]

In my MAC, I ran "killall node" and "yarn start" (or npm start) and everything is fine now.

Yep, it works for me. Thanks, man.

I have an error while running my react code on visual studio. How do you handle the below error???

@nehakuragayala could be an error with the npm global config. Take a look at Error: EACCES: permission denied

[Primo1991]

at linux - sudo npm install then change port, or closing existing server at this port.
that how i fixed it

[deepkesh26]

For what it's worth, I ran npm install npm update and it works again.

I had the same error

This might be because your project port number and live-server port number are different

An easier way around this (if you are using vs code) is to install the live server extension
After that right click the file you want to open and select 'Open with live server'
In my opinion, that's much easier than changing the default port number of every project
Hope that helps

[gabmen1711]

For what it's worth, I ran npm install npm update and it works again.

This one worked for me

[chriswang-]

I run into this issue, It is simply to clean the app/build dir. That will resolve the problem.

[sheecegardezi]

I had another node development server running in another terminal, once I closed that this error was fixed.

CHROMEDRIVER_FORCE_DOWNLOAD=true npm install chromedriver
fixed it for me.

[figencetin]

Because I've run it twice. Make sure you run once

[akilljain]

I am getting the same issue and i could not find any accurate answer plz help me.

[developerdesigner18]

Delete node_modules
Then run npm install

Worked for me

[qxchen6]

clear node_modules folder , run yarn again works for me .

[khushwantkodecha]

Your site is running at http://localhost:8000
Try changing your port. Like 3000 or 8080.

app.listen(3000)

My 8080 post was taken, so I got this same error

[ehsanasgari]

Had the same issue! Just run sudo npm start instead of npm start and it worked! ;-)

[rahulxyz]

Due to some reason in my system variables my path was not set.
Set this to System variables:
%SystemRoot%\system32

In case it doesn't work, try killing your port already under use. (Source)
netstat -ano | findstr :yourPortNumber
taskkill /PID typeyourPIDhere /F

[muqadas12]

i am trying to install reactjs but always i got this error .one step before npm start

[muqadas12]

[akagrawat]

In my case, I resolved it by following steps

1. Delete node module files
2. Change in pakage.json
   "react-scripts": "3.4.1" to "react-scripts": "1.1.1"
3. than use npm install

[muqadas12]

Thanks.And through which tutorial you install ReactJs?

I had an error like this and believe I caused it by moving the mySQL Server 8.0 folder outside of the MySQL folder into Program Files. (I originally did this because using mySQL in command line was annoying typing mySQL and then mySQL Server 8.0).
I solved it by using the mySQL installer and it worked!
