try installing locally. and add this path to your system variable: C:\Program Files\nodejs
Reinstall the node.
You have two ways to install Node.js on your computer.
Option 1 – Setup by running the .msi installation file
Its a typical Windows installation and automated. No need to add
entries in environment varaiable
Option 2 – Setup by extracting .zip file
This method does not require admin access and can be used to install
on nodejs on a system on which you dont have admin access such as you
official laptop or desktop.
Removing nodejs is as simple as deleting the folder. You will have
to add entries in environment variable if you want to execute node
command from any location in windows command prompt. https://nodejs.org/en/download/
Based on the screenshot.your access is denied.Would suggest starting the terminal as an administrator before running the command.
This question seems to be repeated of this link but I cannot figure out how to map a drive letter or share network. I am really sorry for repeating but I need help.
I have a command prompt with default directory pointing to my www folder of wamp server.
D:\wamp\www\
I have install other gulp plugin such as gulp-minify. It works fine without any error. But when I try to install gulp-sass it throws error
It happens to me most of the time like, I have been trying to install plugin such as optipng. It shows same error. Seems like it is searching for a "script" folder inside www which is not there. But the script folder is inside the c drive where the nodejs folder exist. Below is the exact path.
C:\Program Files\nodejs\node_modules\npm\scripts
I don't understand why it is searching in my working directory ?
D:\wamp\www\scripts\install.js
The only problem was with the autorun to set the path of command prompt. Few years back I had set the path of my command prompt to D:\wamp\www\ from registry HKEY_CURRENT_USER\Software\Microsoft\Command Processor
You can access the registry by typing "regedit" in run dialog box (window + r)
i just deleted the autorun file and it started working normally.

I'm trying to figure out if there is a way to change the Node.Js command prompt default path = C:\users...> (default when the prompt is launched) or C:\Windows\System (if launched with administrator privileges), to the location of the folder where i'm working.
Normally I have been doing C:\users..> cd C:\xampp\htdocs..... to navigate to the test folder and run test. Although once the command prompt is closed it reverts back to C:\users...>.
To achieve what I want I came across using Z:>C:\xampp\htdocs\projects.... but this returns access denied with or without administrator privileges. Even if I try C:>C:\xampp\htdocs\projects.... still get the Access Denied for some unknown reason. To be honest I don't know what Z:> or C:> will result.
Is it possible to change the default prompt path to the path of the directory I am working in so that every time command prompt is launched it goes to that directory? In this case C:\xampp\htdocs\projects.... instead of C:\users...>
This seems like a general windows CMD question. Simply change the start up directory for CMD. See this SO post.
Once you're in that directory, you should be able to run the node command as normal.
Look inside your default nodejs installation folder for a file called nodevars.bat. Here is my path:
C:\Program Files\nodejs\nodevars.bat
Open this and look towards the bottom--the line I needed was on the very bottom. Here is the line from the git master:
if "%CD%\"=="%~dp0" cd /d "%HOMEDRIVE%%HOMEPATH%"
I changed mine to
if "%CD%\"=="%~dp0" cd /d "C:\Users\David\Desktop\work\J\math"
And now I am happier.
I had the same question, today, 4/11/22, and DuckDuckGo provided this as the number one result for my query. Since the question appears to be unanswered, I will try for those who might show up later.
I get this error in my app:
Error: EPERM: operation not permitted, open 'C:\Program Files
(x86)\Full Menu\db\main.json'
The app I have is built with electron-boilerplate. I am using this function to get the path to the root of the app:
path.dirname(process.execPath)
And this is the script that writes the file:
fs.writeFile(apath + '/db/' + elem + '.json', JSON.stringify(results)
I know what the problem is: permissions. But how could I get this working without running the app as an administrator?
For the benefit of searchers; I has this error. I added full permissions for Everyone as a test, but that didn't fix it. The issue was that the file was set to readonly (by source control).
Unchecking the readonly option in the file properties fixed the issue.
On my Windows 10 machine, I encountered this error when running an old Node JS project. I think Node version 10.16.
In any case, it was trying to modify a dotfile in my project. Be sure that the file isn't hidden on Windows. After unchecking the hidden option in the file properties pop up. Everything worked.
So to fix:
Right click file in Windows Explorer
Select properties
Uncheck Hidden
Click Ok
Re-run your command.
If you have the file that you can't open or modify mounted as a volume in docker restarting docker should fix the issue.
i had to run the node command prompt as administrator and that fixed the issue.
I face this issue when I was deleting a file/folder.
Solution:
Just restart your code editor/ terminal
Or
Restart your computer
If you are facing this issue on Windows 10, then please try the following:
Uncheck readonly options for the folder (if read-only reverts, login as administrator)
Open terminal as administrator (if you are facing this issue on terminal)
Switch off ransomware folder protection
Change chmod of the folder
Check if the folder is hidden or not
Disable antivirus protection (temporarily) and try this
Or move your project folder somewhere else, where antivirus ransomware protection is disable.
If nothing above works, then try the following:

Hope this would of help.
I think that you must change the permissions recursively to the file so the user executing your script can read / write this file.

Restarting my computer fixed this problem for me.
I had this issue too. I'm using TFS (or VSO, Azure DevOps, etc.) for source control. I was trying to compile from .scss to .css and it couldn't open my .css. I just needed to right-click on my .css file and Check Out for Edit...
I had the error because i have already open the file before
var stream = fs.createWriteStream(outputFileName, {flags:'a'})
var output = fs.createWriteStream(outputFileName, {flags:'a'})
this is not an exact answer but may help:
i think if you want to read or readSync a file that doesn't exist you will encounter an EPERM error...
in many programming languages, any permission related error may not
directly means an actual permission issue
for example in PHP Folders (not files) must delete by php rmdir() method but if you want to do that with unlink() , u will encountered with a wrong Warning message that says "permission denied"
I was facing the same problem using the following software:
Windows 10
GitBash
Node v19
I was able to solve it opening GitBash as admin
I had the same problem, when i tried to create and write to a file using NodeJS. I thought it had to do with my windows file/folder access permissions, but after restarting my computer and running the code again, I still got the same error.
However, this time around my antivirus gave me a pop-up message also, stating that it blocked permission for Node.exe to write or open files. So once I flagged Node.exe as safe for my anti-virus program (Avast).
It worked for me. Disabling my antivirus could've also temporarily fixed it, I guess.
If you use windows 10, you must turn off Ransomware protection. Ransomware protection will prevent all folder and file changes.You can turn off it in Windows Security Center. See screenshot below:
im trying to install xampp on "new" linux mint machine.
However im quite a noob to linux since i havnt used it for that long.
When i try to run the file that ive download from the following page:
Xampp download
i get the following error two errors:
Could not display "/home/marc/Downloads/xampp-linux-x64-1.8.3-0-installer.run".
and if i click yes
Installing mime type handlers isn't supported
To search and install software which can open certain file types you have to install app-install-data.
can anyone tell me what the problem is and how i might fix it?
you need to execute the file (e.g. open a terminal, navigate to your Downloads folder and run bash xampp-linux-x64-1.8.3-0-installer.run (possibly it might need to be run otherwise, but thats my best guess)).
alternatively you might be presented to run/execute the file (instead of displaying it). if so, choose this option.
on the other hand, you might consider installing apache/php/mysql via your package manager.
what you can do is that you can use the chmod +x /your folder location/.run file that you want to install
after that you can run following command
./and your .run file name
example:-
in my case :- User#user~$su root
it will ask for password so give it
User#user~chmod +x /Downloads/xampp-linux-x64-1.8.3-0-installer.run
User#user~./xampp-linux-x64-1.8.3-0-installer.run
