Every time I try to install packages using npm install, I'm getting npm ERR! Tracker "idealTree:inflate:" already exists error.
I've tried removing node_modules and clearing cache, but no luck for me.
I had the same issue when trying to update a v1 lockfile to v2 with npmv7, as it seems to be the case in your codebase, and the only way to make it work was to delete the lockfile, clear the cache and do a npm i again with the --prefer-dedupe flag.
With the package-lock rebuilt, npm i with no flag worked again, as did npm ci.
Before that, I tried npm i --legacy-peer-deps as it seemed to mimic npm v6 not installing peer dependencies and it failed too, however I think it's interesting to know this flag exists, check out the npm 7 announcement page for more clues : https://github.blog/2021-02-02-npm-7-is-now-generally-available/#peer-dependencies
TLDR
rm package-lock.json
npm cache clear --force
npm i --prefer-dedupe
npm update && npm i works for me.

What worked for me was:
Remove package-lock.json and node_modules on the project root.
npm cache clear --force
npm install --legacy-peer-deps
Note: I need to install the dependencies with the flag because of the nature of the project, but it should work just by normally reinstalling the deps with npm install.
This error occurs in node v14, I upgrade to node v16.17.0 fix it
This might help others:
In my case I had a very small web app. Just a 'app.js' and a 'readme.md'. No 'package.json'. When deploying (using Azure Deployment Center) it returned with error 'Tracker "idealTree:inflate:" already exists'.
When I committed a 'package.json' file the deployment succeeded.
npm ERR! Unexpected end of JSON input while parsing near '...--END PGP SIGNATURE--'
I keep getting this error while trying to install node-saas. I have even tried disabling anti-virus & windows defender.
I am using this command to install node sass:
npm install node-sass
Please check the below steps:
Please delete your package.lock.json file, along with that delete your node_modules folder.
Then clear all your npm cache by npm cache clean --force.
Install node-sass globally by using npm install -g node-sass
Once done with node-sass that run your npm install && npm start.
Hope this should work fine.
I tried installing a package in my react app using npm, and for some reason It fails:
it shows the following error:
npm ERR! Object for dependency "#babel/generator" is empty.
npm ERR! Something went wrong. Regenerate the package-lock.json with "npm install".
npm ERR! If using a shrinkwrap, regenerate with "npm shrinkwrap".
I tried npm install to regenerate the package-lock.json but it's the same as before.
TLDR
There is some dependency error with npm, so how about clear project
Answer
First of all, How about clear node_modules and package-lock.json
rm -rf ./node_modules package-lock.json
and retry install with
npm install or npm i
and what I want to say is clear package-lock.json and node_modules. If you'd like to get more information about deleting here is the link
What version of the babel (and it's sub-modules) do you use? Show rows from your package.json file (related to babel).
Your issue possibly could be resolved by updating all babel-related modules
When creating a new Angular 5 project:
node version: 8.9.2
npm version: 5.5.1
My Command is:
npm install -g #angular/cli
The Error is:
npm ERR! **Unexpected end of JSON input while parsing near '...nt-webpack-plugin":"0'**

The error log is here
This solved it for me:
Open Windows Powershell as admin
npm cache clean --force
npm install -g #angular/cli
https://devblogs.microsoft.com/premier-developer/getting-started-with-node-js-angular-and-visual-studio-code/
Solution:
npm cache clean --force
then try again to create your app (here when creating a react app) or install what you were about to install.
create-react-app myproject
(creating react app)[same npm problem that can occur in different operation]
npm install -g #angular/cli#latest
(installing angular cli (or installing anything else))
It will work.
explanation:
That's a problem related to npm, it's about the cache that get corrupt. Even though in newer versions of npm they implemented self healing, which normally guarantee no corruption, but it seem it's not that efficient.
Forcing clean cache resolve the problem.
The error happen when parsing one of the cache files, which have a json format. The cache is found at ~/.npm/_cacache (in linux) and %AppData%/npm-cache (windows). For my current npm version and when i checked, there was three directories.
if you check the first or the second, the structure is as follow
And each cache file have a json format (and that what get parsed)
Here a good link from the doc: https://docs.npmjs.com/cli/cache
[Update] Also if it happen that this didn't solve it, you may check this answer here https://stackoverflow.com/a/50191315/7668448 it show how you can change the npm registry, that can be helpful. Check and see.
If
npm cache clean --force
doesn't work.
try

Npm uses Cache for downloading new packages for you.
You need to clear your npm cache.
use following command to clean :
npm cache clean --force
then normally use your npm install command
e.g.
npm install -g #angular/cli
I solve that with
npm cache clean --force
then update npm
npm i npm#latest -g
then normally use your npm install command
npm install
delete npm and npm-cache folders in C:\Users\admin\AppData\Roaming\ (windows)
then execute cmd
npm cache clear --force
npm cache verify
update npm to latest version
npm i -g npm
then create your project
1)Angular
npm i -g #angular/cli#latest
ng new HelloWorld
2)React
npm i -g create-react-app
create-react-app react-app
None of the 30 answers here worked for me. I needed to:
delete node_modules and package-lock.json
npm cache clean --force
npm install -g #angular/cli
npm i --package-lock-only
npm ci
Phew!
this solved it npm cache clean --force
Simple solutions:
npm cache clean --force
npm install
This command alone solved my problem:
npm cache clean --force
Also you should make sure you are using the correct version of node.
Using nvm to manage the node version:
nvm list; # check your local versions;
nvm install 10.10.0; # install a new remote version;
nvm alias default 10.10.0; # set the 10.10.0 as the default node version, but you have to restart the terminal to make it take effect;

Note: since its a clean install, I had no concerns emptying npm cache.

This occurs when installing the expo CLI globally, This works for me!
npm cache clean --force
I got error (file already exists --force to overwrite) after running the following code:
npm cache clean --force
npm install -g #angular/cli
I solved it using :
npm i -g --force npm
Make sure to run the first commands to flush the cache of npm.
It's error from your npm....
So unistall node and install it again.
It works....
PS: After installing node again, install angular cli globally.
npm install -g #angular/cli#latest
I solve that with
First delete package-lock.json
npm cache clean --force
then update npm
npm i npm#latest -g
then use npm install command
npm install
If you looking for npm install and getting same kind of error
Delete package-lock.json and npm cache clean --force and try
In my case I changed the network to a much stronger one and npm install worked perfectly:
npm cache clean --force
If npm cache clean --force doesn't resolve the issue, try deleting the ~/.npm directory (*nix/macOS). This is the directory where node stores its cache, locks, logs, global packages (unless you're using nvm), and modules installed via npx.
First, backup your current ~/.npm directory:
mv ~/.npm ~/.npm-backup
Now try running your npm command again. This will create a new ~/.npm directory. If the issue is resolved, you can safely remove you backup. Before doing so, you may want to review the global packages installed in your ~/.npm-backup directory so you can reinstall them using npm i -g [package].
rm -rf ~/.npm-backup
If the issue is not resolved, you can restore your backup:
rm -rf ~/.npm
mv ~/.npm-backup ~/.npm
Careful with those rm commands, folks!
Instead of clearing the cache you can set a temporary folder:
npm install --cache /tmp/empty-cache
or
npm install --global --cache /tmp/empty-cache
As of npm#5, the npm cache self-heals from corruption issues and data extracted from the cache is guaranteed to be valid. If you want to make sure everything is consistent, use npm cache verify instead. On the other hand, if you're debugging an issue with the installer, you can use npm install --cache /tmp/empty-cache to use a temporary cache instead of nuking the actual one.
For me I had to clone my branch again and do npm install
You can use yarn package manager instead of npm.
It solved this problem for me
