Issue when installing the last version of appcelerator studio - appcelerator

From this post on appcelerator blog, titanium studio is compatible only from version 6 of node and lower, actually the studio automatically install the last version of node which is the v7 and the CLI + Liveview is not compatible with this version.
I always get this error with live view :
File Server unavailable. Host Unreachable # 127.0.0.1:8324
Could someone confirm me the best node version for titanium studio?
Thank you.

Appcelerator Studio 4.8.0/SDK 6.0/CLI 6.0 requires Node 4.2 and higher. However, Studio installs 4.6.0 as the default node version.
To avoid issues, it's better to have a node version between 4.2 to 4.6.

Xamarin - How to update Mono.Android version to resolve dependencies?

I'm trying to install a nuget package (Xamarin.Firebase.Firestore) which requires a newer version of Xamarin.GooglePlayServices.Basement (60.1142.0, I have 42.1021.1), which in turn requires me to update the xamarin.android.support packages. When I try to update those, I get this error
"Package Xamarin.Android.Support.Design 27.0.2 is not compatible with monoandroid80 (MonoAndroid,Version=v8.0). Package Xamarin.Android.Support.Design 27.0.2 supports: monoandroid81 (MonoAndroid,Version=v8.1)"
I've tried changing my target android version to 8.1, I've also updated my SDK as well as the build tools. I'm running Visual Studio 15.6.1. As a last ditch effort, I tried deleting the Mono.Android V8.0 reference and then adding a new reference to V8.1, but whenever I do so, Visual studio just ends up adding the reference with the path pointing to V8.0, even though the reference I added was clearly pointing to V8.1.
Anyone has a clue how to resolve this issue?
tried changing my target android version to 8.1
You need to change the Target Framework that is used to compile your android application, not the Target Android version (but assumably you would set these two to the same, read the Understanding Android API Levels link below.
Visual Studio for Windows:
Visual Studio for Mac:
Target Framework – Specifies which framework to use in building your application. This API level is used at compile time by Xamarin.Android.
Minimum Android Version – Specifies the oldest Android version that you want your app to support. This API level is used at run time by Android.
Target Android Version – Specifies the version of Android that your app is intended to run on. This API level is used at run time by Android.

can't update or install any nuget packages in vs 2017

I just installed vs 2017 and wanted to run my project but i'm facing so many warning and errors so I realized I should update my xamarin.android nuget packages but I keep getting this error message below:
Severity Code Description Project File Line Suppression State Error Could not install package 'Xamarin.Android.Support.Animated.Vector.Drawable 27.0.2-preview1'. You are trying to install this package into a project that targets 'MonoAndroid,Version=v8.0', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author. 0
Repairing vs didn't work; deleting nuget.config didn't work; I even changed the version in .csproj file, but when i load the project it goes back to v8.0.
Can anybody please help?
can't update or install any nuget packages in vs 2017
Just as Jon said, the latest nuget package Xamarin.Android.Support.Animated.Vector.Drawable 27.0.2-preview1, which requires MonoAndroid81 at minimum to install.
However, only the latest Preview (15.6 Preview 2) version of Visual Studio includes Android 8.1 support. As this moment, current release version is 15.5.4, preview release version is 15.6 Preview 2. So if you want use that nuget package the latest version 27.0.2-preview1, you need download the latest version of Visual Studio 15.6 Preview 2 and install Android SDK 8.1.
If switch to Visual Studio 15.6 Preview 2 is not your choice, you should not update that package to the latest version, just use the version 26.1.0.1.
Hope this answer more clear.
This requires MonoAndroid81 at minimum to install. You can use the current Preview which includes Android 8.1 support:
https://blog.xamarin.com/xamarin-android-now-double-stuffed-with-oreo-8-1/
For future reference, the support library has a major version that maps with the Android version it supports. In this case Support v27 = Android 8.1 (API 27)
When errors appear, clean your solution and rebuild it.
Also do something very basic, that what you are going to download is "accessible " in .Droid and that is not only in the Portable.
If you do not serve, and do not find a solution, you must start a new project, it would be advisable to install the latest SDK, etc.

Azure SDK 2.0 Upgrade button not available

I installed the latest Azure SDK 2.0 on my development machine, but can't find the "Upgrade" button to upgrade my current project to the latest SDK. Googling how to upgrade show that previous upgrades had an "upgrade" button when going to the Cloud Project -> Properties -> Application Tab and the upgrade button will be next to the Windows Azure Tools Version: October 2012.
Why wouldn't I see the Upgrade button? If I want to manually upgrade my project, what would the process of doing so be?
The current version of the SDK used is SDK 1.8
It turns out when I opened the Web Platform Installer to install the latest SDK, the item that said "...SDK... - Latest" wasn't the latest, but the February 2013 (1.8.1) update instead of the 2.0 SDK. I ended up uninstalling all Azure SDK's, restarted the machine and tried again.
This solved the issue and I was presented with a new option to install the 2.0 SDK. The trick was to uninstall all (including any PowerShell cmd's) Azure related products I could find in Product and Features (Win 8).
