[angular-cli] Global Angular CLI version greater than local version

When running ng serve I get this warning about my global CLI version being greater than my local version. I don't notice any issues from this warning, but I was wondering if the two versions should be in sync? Also, Is it necessary to have a local version if you have a global version?

The warning:

Your global Angular CLI version (1.1.1) is greater than your local version (1.0.6). The local Angular CLI version is used.

Two ways to solve this global and local angular CLI version issue.
1. Keep a specific angular-cli version for both environments.
2. Goto latest angular-cli version for both environments.

1. Specific angular-cli version

First, find out which angular version you want to keep on the global and local environment.

ng --version

for example: here we keeping local angular CLI version 8.3.27

So, we have to change the global version also on 8.3.27. use cmd>

npm install --save-dev @angular/[email protected] -g

here, '-g' flag for a set global angular-cli version.

2. Goto latest angular version for both CLI environment.

npm install --save-dev @angular/cli@latest -g  
npm install --save-dev @angular/cli@latest 

Update Angular CLI for a workspace (Local)

npm install --save -dev @angular/cli@latest

Note: Make sure to install the global version using the command with ‘-g’ is if it installed properly.

npm install -g @angular/cli@latest

Run Update command to get a list of all dependencies required to be upgraded

ng update

Next Run update command as below for each individual Angular core package

ng update @angular/cli @angular/core

However, I had to add ‘–force’ and ‘–allow-dirty’ flags command additionally to fix all other pending issues.

ng update @angular/cli @angular/core --allow-dirty --force

if you upgraded your Angular Version, you need to change the version of

@angular-devkit/build-angular

inside your

package.json

from your old version to the new angular build version upgraded.

I had upgraded to Angular 10, so i needed to go to https://www.npmjs.com/package/@angular-devkit/build-angular and check which is my version according to Angular 10.

In my case, i founded that the version needs to be 0.1001.7, so i changed my old version to this version in my package.json and run

npm --save install

That was enough.

This is how I solved the issue.

Copy and run these commands

ng --version
npm install --save-dev @angular/cli@latest
ng --version

This works for me: it will update local version to latest

npm uninstall --save-dev angular-cli
npm install --save-dev @angular/cli@latest
npm install

to verify version

  ng --version

Run the following Command: npm install --save-dev @angular/cli@latest

After running the above command the console might popup the below message

The Angular CLI configuration format has been changed, and your existing configuration can be updated automatically by running the following command: ng update @angular/cli

npm uninstall --save-dev angular-cli
npm install --save-dev @angular/cli@latest

Your existing configuration can be updated automatically by running the following command:

ng update @angular/cli

or:

npm install

In my case I just used this command into project:

ng update @angular/cli

There is another way to avoid the global installation to create a new application. In my case I'm using Angular 9 but the customer requires Angular 8.

# create an empty directories
mkdir angular-8-cli
mkdir my-angular-8-project

# init empty npm project
cd angular-8-cli
npm init -y

# install local angular 8 cli
npm i @angular/cli@8

# go to your angular 8 project
cd ../my-angular-8-project

# use previously installed angular 8 cli to create a new angular 8 project
../angular-8-cli/node_modules/.bin/ng new my-angular-8-project --directory=.

This is how I fixed it. in Visual Studio Code's terminal, First cache clean

npm cache clean --force

Then updated cli

ng update @angular/cli

If any module missing after this, use below command

npm install

I'm not fluent in English

but if I understand the problem, is it that locally in the project you have an older version of CLI than globally?

And would you like to use this global newer instead of the local older one?

If so, a very simple method is enough to run in the project directory npm link @angular/cli

npm install --save-dev @angular-devkit/build-angular - did helped ng update @angular/cli -> did create angular.json and other updates.

It is caused because global and local angular versions are different. To update global angular version, first you need to run the following command in command prompt or vs code terminal

npm install --save-dev @angular/cli@latest

After that if there are any vulnerability found then run the following command to fix them

npm audit fix

You just need to update the AngularCli

npm install --save-dev @angular/cli@latest

Just do these things

npm install --save-dev @angular/cli@latest
npm audit fix
npm audit fix --force

this should solve the issue:

ng update @angular/cli @angular/core

npm uninstall -g @angular/cli
npm cache verify
npm install -g @angular/cli@latest

Then in your Local project package:

rm -rf node_modules dist 
npm install --save-dev @angular/cli@latest
npm i 
ng update @angular/cli 
ng update @angular/core
npm install --save-dev @angular-devkit/build-angular

Was getting below error Error: Unexpected end of JSON input Unexpected end of JSON input Above steps helped from this post Can't update angular to version 6

First find out the global angular-cli version by running

ng --version

The above code will show what version is the global and local angular-cli versions.

If you want the global and local angular cli to be same you can just do

npm install --save-dev @angular/[email protected]

where 1.7.4 is your global angular-cli version

Then if you run ng serve --open your code should run.
