libhostfxr.dylib could not be found

$ hello> dotnet new

A fatal error occurred, the required library libhostfxr.dylib could not be found at /usr/local/bin/

Info

So happy to heart that .netcore support macOS sierra, but while I have tried that's still a big disappointment!

@steveharter any ideas?

[steveharter]

Some troubleshooting recommendations:
1) Verify the dotnet executable location - type which dotnet.

For you it appears that it is going to be /usr/local/bin/. However the default install location (and on my mac) is /usr/local/share/dotnet/

Do you happen to have an old install at /usr/local/bin/ that is in the path? Normally /usr/local/bin is going to be in the path before /usr/local/share/dotnet (verify via echo $PATH)

2) Fom the dotnet executable location there should be a subfolder called host/fxr/2.0.0 with the libhostfxr.dylib file

3) Try setting export COREHOST_TRACE=1 and then run dotnet new again to get any further diagnostics

@steveharter
Thank you very much your advises!

It seems to be the Permission problem at last after tried many times, it showed "Permission Denied".
But it worked fine once time if export the /usr/local/share/dotnet to $path and ln -s source correctly, close it and try again all was gone, which dotnet was none too.

Summary up, not permission enough to execute the application, although tried update right as 'sudo chown -R user_xxx /usr/local/share/dotnet' or 'sudo chmod -R 7xx /usr/local/bin/dotnet'.

Regards & Thanks!
