[2.5.*] tns run always add latest platform

[tsonevn]

From @3rror404 on May 4, 2017 15:52

I'm still using N 2.5.4 as I don't have time to upgrade to version 3 yet.

After I removed the iOS platform and re-added I noticed that the platform had been upgraded to 3.0.0. After removing the platform again and reinstalling the 2.5.0 version with tns platform add ios@2.5.0 I can no longer run my project.

Project successfully prepared (ios)
Searching for devices...
Building project...
Expected "// !$*UTF8*$!" but "<" found.
# run ios

I've tried numerous things including removing iOS and installing the 3.0.0 version. Removing the hooks, node_modules and platforms folders all with the same result.

Any ideas?

Hi @3rror404 ,
Thank you for reporting this issue.

I tested it on my side and I have to confirm that this is a real issue, while using an old CLI.
If we have an old project, using runtime 2.5.0 and build with tns run <platform_name> tns-iosandtns -android` will be automatically updated to version 3.0.

Workaround:

1. tns platform remove <platform_name>
2. tns platform add <platform_name>@2.5.0
3. tns prepare <platform_name>
4. tns run <platform_name>

I think that this workaround isnt working with me.. I'm using tns 2.5.4 and it is still installing tns-android 3

[3rror404]

Same here.

[tsonevn]

Hi @Cae2, @3rror404
Excuse me for the mistake. I forgot to specify the runtime version while adding the platform. For example: tns platform add <platform_name>@2.5.0. I also update my previous answer.
Now the workaround should work for you.

[3rror404]

I did actually try that thinking that you might have made a mistake and I still received the same error:

Expected "// !$*UTF8*$!" but "<" found.

The workaround doesn't work when I try publish a bundled version.
ns-bundle removes the platform and adds it against, so I'm still have tns-android@3.0.0.
