iam getting below error with npm while creating react app
npm ERR! Cannot read properties of null (reading 'pickAlgorithm')
npm ERR! A complete log of this run can be found in:
npm ERR! C:\Users\Nagamanickam\AppData\Local\npm-cache_logs\2021-11-18T12_01_45_525Z-debug.log
my npm version is 8.1.4 and i solve this problem by running :
npm cache clear --force
I resolved it by deleting node_modules and package-lock.json and run npm install again.
solved with npm i --legacy-peer-deps on react-native version .70
Just run these 2 commands :
npm cache clear --force
npm install
Probably it's a project that works with Yarn and not NPM.
Try Yarn instead of NPM.
yarn install
and then you can do
yarn start
or
npm start
Your dependency tree may be broken (due to incompartible peer dependencies) you can try running npm install with --legacy-peer-deps or --force to bypass this issue for the mean time.
I was getting this error from an old branch that had a previous version of node/npm. using the correct version of node helped in my case.
In my case the file .npmrc was corrupt. After deleting it everything worked.
I was getting the same error, but I was able to resolve it by the below described method:
Go to folder -> Local > npm-cache and delete all contents of the npm-cache.
try again with npm command, it should work now.
I solved this by update npm from 6.x to 8.5x, then run npm cache clear --force, npm install, however, it has to change the nodejs from 14 to 17, my env is macOS m1 pro.
In my case i updated npm via:
npm update -g npm
After it, everything worked fine.
Don't know why, i didn't expect it.
I solved deleting node_modules and running this command:
npm cache clear --force

I'm having this error since a while, in this case, the problem occur executing the following command.
npx create-react-app my-app
Actually, it happens with any npm commands as well, I tried deleting package.json, changing npm versions and yet didn't work, so I'm here asking for help.
This is the entire error:
C:\Users\c>npm install
npm ERR! must provide string spec

Version of npm and node:
node --version
v16.13.2
npm --version
8.3.2
I had the same issue, it was a missing version in my package.json
look like mistakenly I removed some text
"dependencies":{
"angular/cli" :"{}"
}
try to update your npm: npm upgrade
then: npm clean cache
Following, i'm in the exact same position. Tried changing the NodeJS version using NVM and now some of the commands work (npm -v shows im running 8.1.0) but npm update and npm/npx create-react-app give me an " ERR! must provide string spec " !
I faced this same issue yesterday.
This is what I did to resolve it:
Uninstalling node entirely and removing node_modules and package.lock.json from the project directory.
Install node afresh and run npm install in your project directory.
I tried to reactivate an old project which had packages noted down differently then usual in package.json. They had an id and locator parameter, like:
"ImagePicker": {
"id": "ImagePicker",
"locator": "https://github.com/dhavalsoni2001/ImagePicker.git"
}
After removing / replacing them by version numbes, i could install.
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.
I am having an issue installing csvtojson. When I run npm install csvtojson I'm getting npm error tb.match is not a function. How do I solve this?
If you cant get to use NPM right away, try to use YARN and see if the dependencies will install
Removing the lock file AND the node_modules folder worked for me. Try to remove them and run again npm install.
Remove package.lock and run npm install is working for me.
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:

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 cache clean --force
npm update
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

None of the 30 answers here worked for me. I needed to:

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;

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.
