[vlio20]

I am not sure that I understand the bug. please elaborate

[MerkulovDev]

installed datepicker. imported in module. trying to run project and got this error Metadata version mismatch for module /projectFolder/node_modules/ng2-date-picker/index.d.ts, found version 4, expected 3, resolving symbol...

[vlio20]

I will need a stackblitz

[mdarfilal]

I got the same error today, when passing node 6.9.4 to 8.9.4 npm 3.10.10 to 5.6.0 Before that worked well

[vlio20]

Please provide a stackblitz

[denispodtykan]

I have the same error on the version of angular 4.2.4, if I run on 5.2.0 all is well

[vlio20]

@denispodtykan thanks... If anyone can help with that would be great.

[denispodtykan]

I found a strange way to solve In the folder /node_modules/ng2-date-picker/ I replaced all occurrences of "version": 4 to "version": 3 and it all worked for me, I do not know how right it is

[vlio20]

It is auto-generated, so we need a more deterministic solution

[denispodtykan]

Of course, therefore, and pointed out that this is not entirely a solution)

Now I tried to change the version from 2.7.3 to 2.6.1 all worked correctly

[mdarfilal]

For information, upgrade angular 4.2.4 to 5.2.1 (latest) ng2-date-picker 2.6.2 to 2.7.3 (latest)

no more problem.

[vlio20]

The question is: is there a way to make the date picker backward compatible to version less than ng5

[uweDuesing]

@mdarfilal The problem with this approach is that in big complex projects simply upgrading everything is a huge task

[uweDuesing]

I have the same problem and I agree with vlio20, the date picker needs to be backwards compatible.

[MerkulovDev]

I cant upgrade angular to v5 because a have many modules and there dependencies that would not work on v5.

[vlio20]

@MerkulovDev please use version 2.6.2

[MerkulovDev]

yes. i've tried 2.6.2 but some options is not working like 'firstDayOfWeek' and 'unSelectOnClick'. i will try 2.6.2 now

[MerkulovDev]

in 2.6.2 everything is worse Type '{ firstDayOfWeek: "mo"; monthFormat: string; disableKeypress: false; allowMultiSelect: false; clo...' is not assignable to type 'IDatePickerConfig'.

[vlio20]

@MerkulovDev, please open a different issue, and provide a stackblitz for the issue that you are having 2.6.2

[vlio20]

@MerkulovDev , @uweDuesing, @mdarfilal , @denispodtykan I have just deployed 2.7.4-alpha version could you please try it out and let me know if it works for?

[nitinsh99]

I was also getting this error which seem to have been resolved for me in 2.7.4-alpha.

ERROR in Error: Metadata version mismatch for module .node_modules/ng2-date-picker/index.d.ts, found version 4, expected 3, Thank you for fixing this.

[vlio20]

@nitinsh99 thanks. I will wait for few more replies and will publish a stable version

[vlio20]

@MerkulovDev , @uweDuesing, @mdarfilal , @denispodtykan any updates?

[mdarfilal]

@vlio20 Since this issue I updated my angular/node/date-picker version to latest. I just tried the version 2.7.4-alpha, results as follow :

• angular 5.2.0

• node 8.9.4

• npm 5.6 => OK

• angular 4.2.4

• node 8.9.4

• npm 5.6 => OK

[vlio20]

Awesome, will make a new release soon

[vlio20]

should be fixed in 2.7.4
