“Unexpected Token <” error in HTML while using socket.io via npm - npm

I know this issue has been discussed in an old post. But in that scenario the developer was importing socket.io via a script tag. I am getting the same error on my local build and I have installed socket.io using npm.
Has anyone had a similar issue? How can this be corrected?

Turned out to be an npm cache issue for me. After several attempts I was able to resolve this by clearing my npm cache, deleting all of the modules, and then re-running npm install.

npm install on VueJS

I am trying to install this script. I am trying to run npm install command. But this is not working. This is stuck after message idealTree:color-convert: timing idealTree:node_modules/c.
Could anyone help me to install this script ?
I tried it myself and had the same issue.
There might be an issue on the author's end or with some dependency.
Try contacting the author of the package to investigate the issue.
You can create an issue here: https://github.com/creativetimofficial/vue-notus/issues
nice you can delete your node modules and try again...
or you can try npm cache clean
if both fails you can try yarn...

How can i solve this vue related issue

Am trying to create a vue project using command line but it is showing this error message:
Error unexpected end ofJSON input while parsing near '....67e12ef","tarball":"h'
Using command line, I created a new project in C directory after which, I installed vue using NPM. After that I try installing #vue/CLI globally using NPM but while installing it the above error sprout out.
Have done npm cache clean --force but still the same error..
It is hard to suggest anything because your question lacks details.
However this error often appears as a problem with npm itself.
Consider cleaning npm's cache with following commands:
npm cache clean --force
npm cache verify
If the problem will still occur, please provide more details.

Error 403 - Forbidden while trying npm install

So just like every day I do different projects and install additional modules, today I want to install another module and such an error, reinstall the server and still the same .... [Error]The error appeared overnight
I found the issue from here: https://github.com/npm/npm/issues/2119#issuecomment-5321857
It's a very common issue in npm. Actually npm is not working good with HTTPS over a proxy. Changing the registry URL from HTTPS to HTTP will fix the problem.
Try this out:
npm config set registry http://registry.npmjs.org

ERROr: **npm ERR! Unexpected token < in JSON at position 0 while parsing near '<!DOCTYPE HTML PUBLI...'**

Image I am cloning the sitecore Habitat project to my local machine.
After cloning while running npm install, I am getting this error. I tired in all possible ways from the stack overflow answers, but did not succeed with answers still its showing errors, if anyone known about this please let me know.
ERROr: **npm ERR! Unexpected token < in JSON at position 0 while parsing near '<!DOCTYPE HTML PUBLI...'**
Just delete
package-lock.json file
It works for me.
I getting error like:
I found this solution in another question and worked for me after I set the registry like this:
npm set registry https://registry.npmjs.org/
Setting npm Registery worked for me
npm set registry https://registry.npmjs.org/
This error means there is a proxy in the middle which is denying you access to the Internet.
The error comes from the HTML page that is rendered from the proxy.
You need to check with your network administration to either allow the connection through (an exception), or you have to configure the variable HTTP_PROXY in your environment, which is like this:
http://username:password#proxy.server.com:port
Having tested npm install in several repos with the same error I ran npm cache clean --force and tried again. This is not as severe a solution as deleting all traces of node and reinstalling from the ground up.
I use an npm registry hosted at work for internal npm packages so couldn't change the registry source.
yes , its happned due to proxy setting, if this problem occurs, please check your proxy setting, in my case npm was getting blocked, You need to check with your network administration to either allow the connection through (an exception), or you have to configure the variable HTTP_PROXY in your environment
You need to check all required npm config setup like:
https-proxy=https://username:password#accessdomain:port/
proxy=http://username:password#accessdomain:port
registry=https://registry.npmjs.org/
//If required also add
msbuild_path=C:\Program Files\Microsoft Visual Studio\2022\Community\Msbuild\Current\Bin\MSBuild.exe
I was getting the same issue. I had un-installed NodeJs and deleted folders npm and npm-cache from Users\username\Appdata\Roaming folder and installed it.
Then set config registry by using command terminal as.
npm config set registry https://registry.npmjs.org/
To give an actual description of the problem and solution:
This happens when the URL set as your npm registry is incorrect (or as others have mentioned, a proxy has got in the way). Either way, you end up trying to download a package from an endpoint displaying HTML, which npm fails to parse as JSON (as one would expect).
You can view the URL for your npm config with
npm config get registry, and set it with npm config set registry https://my.registry.com/ (or https://registry.npmjs.org/ for the public registry)
I tried everything mentioned here. Nothing worked. Then I moved jsonwebtoken dependency to the bottom of package.json ( Below my registy specific dependencies ).
Then it worked!
Spent 6 hours in fixing this. I feel so small now.

Diagnosing npm’s “invalid” error in package list

When I do npm list --global, one package, phonegap, shows as invalid.
npm ERR! invalid: phonegap#5.0.0-0.28.1 /usr/local/lib/node_modules/phonegap
No other packages have any errors or problems. I’ve tried to look into this, and learned that the message means a dependency is unfulfilled, but I can’t figure out which one. If I run npm update --global phonegap it exits cleanly, with no errors.
I originally installed npm & node via Homebrew, if that’s relevant. Here’s my full list of globally installed packages.
How do I diagnose this?
Have you tried changing the permissions for that package? I recently had a similar problem with global packages and it turned out to be a permissions issue
