How do you read npm audit ERESOLVE error? - node.js

I often receive error ERESOLVE similar to below. How do you read it?
>npm audit fix
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: myapp#0.0.0
npm ERR! Found: #angular/compiler#12.1.0
npm ERR! node_modules/#angular/compiler
npm ERR! #angular/compiler#"12.1.0" from the root project

npm ERR! Could not resolve dependency:

npm ERR! node_modules/#angular-devkit/build-angular
npm ERR! dev #angular-devkit/build-angular#"12.1.0" from the root project
And how do you read it - Which package depends on which? Which end of the tree I have control of? Top or bottom?
Did I add #angular-devkit/build-angular into my app and it needs but cant find angular/compiler ? or is it the other way around?

I can be wrong but this is what I read:
Which package depends on which?
Your app directly depends on:
#angular/compiler#"12.1.0"
#angular/compiler-cli#"^12.1.0"
#angular-devkit/build-angular#"12.1.0"
Your app transitively depends on:
#angular/compiler#"12.1.1" from #angular/compiler-cli#12.1.1 <- which is the actual #angular/compiler-cli version installed in your node_modules.
#angular/compiler-cli#"^12.0.0 || ^12.1.0-next" from #angular-devkit/build-angular#12.1.0 <- which is the actual #angular-devkit/build-angular version installed in your node_modules.
So what I read is that there is a conflict because your app directly depends on #angular/compiler#"12.1.0" and transitively on #angular/compiler#"12.1.1" (from #angular/compiler-cli#12.1.1)
You can probably fix this by adding what it looks like a missing caret, ie #angular/compiler#"^12.1.0".
Unrelated ^, I had a similar problem but all versions where compatible. I deleted package-lock.json and node_modules and installed them again and it worked fine.

I've fixed it with following commands:
rm package-lock.json
rm -rf node_modules
yarn install
npm i

npm ERR! ERESOLVE unable to resolve dependency tree when installing #nest/microservices

I'm trying to install new dependency to my service,
#nest/microservices: ^7.0.3 and got this error:
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: vb-service-ads#0.0.1
npm ERR! Found: #nestjs/common#8.4.7

npm ERR! node_modules/#nestjs/microservices
npm ERR! #nestjs/microservices#"^7.0.3" from the root project
npm ERR!
so versions of packages with problem are:
"#nestjs/common": "^8.4.7",
"#nestjs/core": "^7.6.15"
I tried to upgrade versions of core and microservices dependencies to ^8.0.0, and got more dependencies broken and also tried to downgrade common to ^7.6.15 and got same effect.
Tried to use yarn instead of npm, it resolved my problem, but i need all packages to be installed by npm
So, I resolved this problem, with deleting node_modules, package-lock.json and removing dependencies and devDependencies in package.json
After i've installed all dependencies manually one by one
you can see the solution here, or at least this is what worked for me here. https://www.angularjswiki.com/angular/unable-to-resolve-dependency-tree-error-in-angular-while-installing-npm-packages/
I leave you the part where it worked for me
To fix Unable to resolve dependency tree error in Angular while
installing npm packages follow the below steps.
Run npm install --save --legacy-peer-deps instead of npm install command. Another way is delete the node_modules folder and
package_lock.json file and then
Run npm cache clean --force after npm i --force command.

npm ERESOLVE could not resolve #angular/elements#11.2.14 after trying to update to angular 12

I have a angular 11 application and i wanted to update it to the latest 14, based on the officiel website i had to go update one by one so 11 to 12, 12 to 13 and 13 to 14.
So i created a new branch on git and started [here][1] with ng update #angular/core#12 #angular/cli#12, i had a bunch of dependencies issues after so i rolled back on the master branch, but i still have problems with npm dependencies, everytime i do a npm install i have something like this that i don't understand at all :
npm i
npm WARN config global `--global`, `--local` are deprecated. Use `--location=global` instead.

I tried to do npm install --force and npm install --legacy-peer-deps, but still i can't just do npm install as i'm used to, is there something that breaks angular when doing the ng update.
for the versions that i use i have :
Angular CLI: 11.0.7
Node: 16.15.1
OS: win32 x64
Angular: 11.0.9
npm: 8.11.0
Do you think i need to reinstall angular? I don't get how the project can be broken when i rolled back to the branch before any modification on the project. I feel like the easiest way to update is to create a new project on the version you want and add everything back in it little by little.
if you have any idea on this i'll take it.
Thanks in advance !

Updating Npm packages with unresolved Peer dependencies

I am trying to update react-router-dom however when I try I get an ERR of course. The error ERESOLVE unable to resolve dependency tree
npm update "popper.js" "bootstrap" "react-router-dom" :
Could not resolve dependency:
npm ERR! peer popper.js#"^1.16.1" from bootstrap#4.6.1
npm ERR! node_modules/bootstrap
npm ERR! bootstrap#"^4.1.1" from the root project
npm update popper.js :
Could not resolve dependency:
npm ERR! peer popper.js#"^1.16.1" from bootstrap#4.6.0
npm ERR! node_modules/bootstrap
npm ERR! bootstrap#"^4.1.1" from the root project
npm ERR!
npm ERR! Conflicting peer dependency: popper.js#1.16.1

npm ERR! peer popper.js#"^1.16.1" from bootstrap#4.6.0
npm ERR! node_modules/bootstrap
npm ERR! bootstrap#"^4.1.1" from the root project
And it seems like Im stuck in this loop of not being able to update bootstrap because popper.js is behind and I can update popper.js because of bootstrap.
I am running npm update "popper.js" | "bootstrap" | "react-router-dom" independently.
But no matter what I do I get these same errors.
I am working inside a giant project with alot of dependencies that need updating so I cant just run an update on everything. Can someone explain how I can update the peer dependencies? Ive never done an update like this so any pointer in the right direction would be helpful.
The best option is to run script with flag --legacy-peer-deps it will skip checking peer dependency. Peer dependency should be installed manually in package.json.
Read more about the flag.

Thanks
It looks like you're trying to install vee-validate version 4.0 in a Vue 2.x application. You can see the compatible version in the vee-validate repo.
How to fix:
Option 1:
Install an older version of Vee-validate (v2 or v3).
First, you'll need to uninstall the version you currently have installed (I'm assuming you installed vee-validate#next since that's the doc recommendation)
npm uninstall vee-validate#next
You can then find the list of versions available with
npm info vee-validate versions
Finally, install an older version with
npm install vee-validate#3.4.9
Replace the 3.4.9 with whatever version you would like to install - as of the time of writing, 3.4.9 is the latest stable tag
Option 2:
Upgrade from Vue 2 to Vue 3 following the upgrade guide.
Note that this is still a work in progress and may have some stability issues and depending on the state of the project I would consider using the above option for the time being.
Step:-1 Make sure node.js is installed on your system. You can check with the command npm --version or node --version
Step:-2 Clear npm cache. run this command npm cache clear -f
Step:-3 Then try to run npm install

npm install fails (unable to resolve dependency tree)

Trying to reduce any changing variables and using a fresh pull of my code. They are no node-module packages or package-lock.json. I run npm install I get this error:

If I do an install via --force or npm install --legacy-peer-deps I get a bunch of files mark as outdated and when I run npm update I get the same error. I have tried clearning the cache of my npm as well with no luck npm cache clean. I don't know why this is happening as there is no node-module folder or anything installed for it to give error under my node_modules/react-native-screens...they are no node_modules folder yet. What is causing this and how can I fix it?
Edit:
I ran npm update -g , then npm audit fix and then I got an error:
code ERESOLVE
ERESOLVE unable to resolve dependency tree
While resolving: Sculp latest app#undefined
Found: react-native-screens#2.15.2
node_modules/react-native-screens
react-native-screens#“~2.15.0” from the root project
so I ran expo install react-native-screens and saw that it couldn't find expo...checked my folder and my node_module folder is missing. Like if it never was there or gotten installed.
edit:
I have tried all the methods listed below and it gives random errors that I can not fix it undefined is not an object (evaluating ‘_core.ThemeColors.light’) and I have googled this and one of the main solutions is delete npm and package-lock.json and reinstall but that brings me back to where I started.
It works for me:
npm install --save --legacy-peer-deps
Try this:
npm config set legacy-peer-deps true
Note: this will set this flag permanently
For one time:
npm install --save --legacy-peer-deps
Try to copy your src folder and package.json file and initialize another react-native (new) and replace the source the src folder and package.json file and reenter npm install.
You can use --force in the command line, but you will problably have to deal with a broken react-native dependency later. Anyway, there are other ways of dealing with this broken dependency.
Try it in the following:
npm add react-native
expo install (your needed module)
