Trouble running Home/samples/MvcHello Kestrel on Mac.

[migueldeicaza]

In a previous life, I had K and KVM setup, back when @davidfowl and myself were trying to get things running, and I suspect this might have left some old stuff behind.

I have done a kvm upgrade and this is what kvm list shows:

KRE-mono45-x86.0.1-alpha-build-0475
KRE-mono45-x86.1.0.0-alpha4-10353 *

When I try to run:

k kestrel 

On my Mac, I get this:

System.MissingMethodException: Method not found: 'Microsoft.Framework.Runtime.ILibraryInformation.get_LoadableAssemblies'.

[davidfowl]

You need the new version of kvm. Run that curl command on the readme again.

[davidfowl]

Or use homebrew

[zote]

David, I have same problem here.

And Im using latest version download few moments ago..

zote$ kvm upgrade Determining latest version 1.0.0-alpha4-10353 KRE-mono45-x86.1.0.0-alpha4-10353 already installed. Adding /Users/zote/.kre/packages/KRE-mono45-x86.1.0.0-alpha4-10353/bin to process PATH Setting alias 'default' to 'KRE-mono45-x86.1.0.0-alpha4-10353'

@zote : you are trying to run beta1 packages with alpha4 version of KRE. You need to update your KRE and KVM. Try this

• brew uninstall kvm
• brew update
• brew untap aspnet/k
• brew tap aspnet/k
• brew install kvm
• kvm upgrade

This should update the kvm brew script, install latest kvm and upgrade to KRE. Let me know if this helps

@suhasj Don't worked...

[suhasj]

Ok close the current terminal and try kvm upgrade in the new terminal. Need to reload the kvm.sh

[zote]

Zotes-MacBook-Pro:~ zote$ kvm upgrade -bash: kvm: command not found

[suhasj]

So as mentioned in the installation notes you need to ' Add the following to the ~/.bash_profile, ~/.bashrc or ~/.zshrc file:

source kvm.sh '

[suhasj]

Update source kvm.sh in the .bash_profile if you are running on latest OSX and re open a new terminal and try

[zote]

@suhasj thank you so much, its working now!!!
