Recently I started Angular 2 tutorial at https://angular.io/docs/ts/latest/tutorial/.
and left off with Angular 2 beta 8. Now I resumed the tutorial and latest beta is beta 14.
If I simply do npm update a few modules (preloaded with the tutorial) are updated but not Angular2 (I can see that with npm ls).
If I do npm update angular 2 or npm update [email protected] it just does nothing either.
You can run ng add @angular/localize to include required packages. Finally, run ng update @angular/core @angular/cli command to update to Angular 11. This will migrate your project to latest Angular release. After the update to Angular 11 is done your project will be using Typescript 4.
Run ng update @angular/core@12 @angular/cli@12 which should bring you to version 12 of Angular. Angular now requires TypeScript 4.2. ng update will update you automatically.
The command npm update -D && npm update -S
will update all packages inside package.json
to their latest version, according to their defined version range. You can read more about it here.
If you want to update Angular from a version prior to 2.0.0-rc.1
, then you'll need to manually edit package.json
, as Angular was split into several npm modules. Without this, as angular2 package points to 2.0.0-beta.21
, you'll never get to use the latest version of Angular.
A list with some of the most common modules that you'll need to get started can be found in the quickstart repository.
Notes:
A cool way to stay up to date with your packages' latest version is to use npm outdated
which shows you all outdated packages together with their wanted and latest version.
The reason why we need to chain two commands, npm update -D
and npm update -S
is to overcome this bug until it's fixed.
Another nice package which I used for migrating form a beta version of Angular2 to Angular2 2.0.0 final
is npm-check-updates
It shows the latest available version of all packages specified within your package.json. In contrast to npm outdated
it is also capable to edit your package.json, enabling you to do a npm upgrade
later.
Install
sudo npm install -g npm-check-updates
Usage
ncu
for display
ncu -u
for re-writing your package.json
Upgrade to latest Angular 5
Angular Dep packages:
npm install @angular/{animations,common,compiler,core,forms,http,platform-browser,platform-browser-dynamic,router}@latest --save
Other packages that are installed by the angular cli
npm install --save core-js@latest rxjs@latest zone.js@latest
Angular Dev packages:
npm install --save-dev @angular/{compiler-cli,cli,language-service}@latest
Types Dev packages:
npm install --save-dev @types/{jasmine,jasminewd2,node}@latest
Other packages that are installed as dev dev by the angular cli:
npm install --save-dev codelyzer@latest jasmine-core@latest jasmine-spec-reporter@latest karma@latest karma-chrome-launcher@latest karma-cli@latest karma-coverage-istanbul-reporter@latest karma-jasmine@latest karma-jasmine-html-reporter@latest protractor@latest ts-node@latest tslint@latest
Install the latest supported version used by the Angular cli (don't do @latest):
npm install --save-dev [email protected]
Rename file angular-cli.json to .angular-cli.json and update the content:
{
"$schema": "./node_modules/@angular/cli/lib/config/schema.json",
"project": {
"name": "project3-example"
},
"apps": [
{
"root": "src",
"outDir": "dist",

],
"scripts": [],
"environmentSource": "environments/environment.ts",
"environments": {

}
}

}
}
UPDATE:
Starting from CLI v6 you can just run ng update
in order to get your dependencies updated automatically to a new version.
With
ng update
sometimes you might want to add--force
flag. If you do so make sure that the version of typescript you got installed this way is supported by your current angular version, otherwise you might need to downgrade the typescript version.
Also checkout this guide Updating your Angular projects
If you are on are on Mac/Linux
or running bash on Windows
(that wont work in default Windows CMD
) you can run that oneliner:
npm install @angular/{animations,common,compiler,core,forms,http,platform-browser,platform-browser-dynamic,router,compiler-cli}@4.4.5 --save
yarn add @angular/{animations,common,compiler,core,forms,http,platform-browser,platform-browser-dynamic,router,compiler-cli}@4.4.5
Just specify version you wan't e.g @4.4.5 or put @latest to get the latest
Check your
package.json
just to make sure you are updating all@angular/*
packages that you app is relying on
@angular
version in your project run:npm ls @angular/compiler
or yarn list @angular/compiler
@angular
version available on npm run:npm show @angular/compiler version
Official npm page suggest a structured method to update angular version for both global and local scenarios.
1.First of all, you need to uninstall the current angular from your system.
npm uninstall -g angular-cli
npm uninstall --save-dev angular-cli
npm uninstall -g @angular/cli
2.Clean up the cache
npm cache clean
EDIT
As pointed out by @candidj
npm cache clean
is renamed as npm cache verify
from npm 5 onwards
3.Install angular globally
npm install -g @angular/cli@latest
4.Local project setup if you have one
rm -rf node_modules
npm install --save-dev @angular/cli@latest
npm install
Please check the same down on the link below:
https://www.npmjs.com/package/@angular/cli#updating-angular-cli
This will solve the problem.
Alternative approach using npm-upgrade:
npm i -g npm-upgrade
Go to your project folder
npm-upgrade check
It will ask you if you wish to upgrade the package, select Yes
That's simple
If you want to install/upgrade all packages to the latest version and you are running windows you can use this in powershell.exe
:
foreach($package in @("animations","common","compiler","core","forms","http","platform-browser","platform-browser-dynamic","router")) {
npm install @angular/$package@latest -E
}
If you also use the cli
, you can do this:
foreach($package in @('animations','common','compiler','core','forms','http','platform-browser','platform-browser-dynamic','router', 'cli','compiler-cli')){
iex "npm install @angular/$package@latest -E $(If($('cli','compiler-cli').Contains($package)){'-D'})";
}
This will save the packages exact (-E), and the cli packages in devDependencies
(-D)
https://update.angular.io
Select the version you're using and it will give you a step by step guide.
I recommend choosing 'Advanced' to see all steps. Complexity is a relative concept - and I don't know whose stupid idea this feature was, but if you select 'Basic' it won't show you all steps needed and you may miss something important that your otherwise 'Basic' application is using.
As of version 6 there is a new Angular CLI command ng update
which intelligently goes through your dependencies and performs checks to make sure you're updating the right things :-)
The steps will outline how to use it :-)
npm uninstall --save-dev angular-cli
npm install --save-dev @angular/cli@latest
ng update @angular/cli
ng update @angular/core --force
ng update @angular/material or npm i @angular/cdk@6 @angular/material@6 --save
npm install typescript@'>=2.7.0 <2.8.0'
