Allow ng2-select to work with ng4

[mircowidmer]

When I try to npm install an ng4 project (4.0.0) that is using ng2-select, I get the following warning:

[email protected] requires a peer of @angular/common@^2.3.0 but none was installed.
[email protected] requires a peer of @angular/core@^2.3.0 but none was installed.

I believe that is because the peer dependencies of version 1.2.0 of ng2-select are locked to 2.x.x, see package.json:

"peerDependencies": {
    "@angular/common": "^2.3.0",
    "@angular/core": "^2.3.0"
  },

It should also allow to be usable with ng4 without producing warnings during npm install.

npm shrinkwrap will fail too

Same issue here!i've switched to angular the dependencies to version "2.." but still have the same issue

I am afraid this may never be done, but that's a must if this library is to last a bit longer

[nomanbiniqbal]

any news

[Scipionh]

This lib is dead, let's move on.

A forked version with relaxed dependencies can be used for now:

npm install --save https://github.com/roolebo/ng2-select/tarball/0e798ad4f04a0efccd03a757e3cc587e84906f46

It can be installed on angular 4.x

[roolebo]

Ohh. It seems that the fork should also be rebuilt

[roolebo]

UPD: npm install --save ng2-select-compat installs exact copy of [email protected] with relaxed dependencies
It can be used as drop-in replacement of ng2-select:

import { SelectModule } from 'ng2-select-compat'

Using npm version 5 solved the version locking issue. The new npm generates a package-lock.json file so no more npm shrinkwrap !

[samuelkavin]

I still have sasme error even using ng2-select-compat. Any solution?
Here is my package.json
"@angular-generic-table/core": "^4.4.1", "@angular/animations": "^4.3.4", "@angular/common": "^4.0.0", "@angular/compiler": "^4.0.0", "@angular/core": "^4.0.0", "@angular/forms": "^4.0.0", "@angular/http": "^4.0.0",

@mouradhamoud I'm using npm 5 and still get the same problem. How does it work for you?

[mouradhamoud]

@filipefreitas82 I have the line "ng2-select": "1.2.0" in my package.json file.

The generated package-lock.json contains:

"ng2-select": {
  "version": "1.2.0",
  "resolved": "https://registry.npmjs.org/ng2-select/-/ng2-select-1.2.0.tgz",
  "integrity": "sha1-XJBhi/++MqzF7hwSjIhUcFm08Rw="
},

I didn't need to do anything special.

Extra details: I'm using npm v 5.3.0 and angular v 4.3.2, I hope this will help.

[filipefreitas82]

@mouradhamoud thanks. As it turns out my problem was related to other packages (ngx-bootstrap and ngx-uploader).

Still I'm using npm 5.3.0 with angular 4.3.6 and I'm getting the same warnings:

[email protected] requires a peer of @angular/common@^2.3.0 but none was installed.
[email protected] requires a peer of @angular/core@^2.3.0 but none was installed.

My package-lock.json also has the same as yours:

"ng2-select": {
"version": "1.2.0",
"resolved": "https://registry.npmjs.org/ng2-select/-/ng2-select-1.2.0.tgz",
"integrity": "sha1-XJBhi/++MqzF7hwSjIhUcFm08Rw="
},

[mouradhamoud]

@filipefreitas82 Nice, I have the warnings too but this doesn't prevent the generation of the lock file.

Is ng2-select 1.2.0 going to support angular 4 at some point? I'm getting the warning as stated here with node 8.1.2 and @angular/cli: 1.3.2 and angular 4.2.4.

New life of the component in the fork: https://github.com/optimistex/ng2-select-ex
And currently, it is supported with Angular 5
