convMethodRef: could not bind to method

[flypixel]

error FS0192: internal error: convMethodRef: could not bind to method I get this error, when I try to use paket from fsi on Ubuntu, after I call dependencies.GetInstalledVersion "FSharp.Data" as in the example . Version of mono is 4.2.1.102. Paket version 2.33.1.0

[forki]

yeah that sounds like FSharp.Core issue.

[forki]

did you bind against paket.exe or Paket.core?

[flypixel]

paket.exe, like in the example

[forki]

Which VS version and f# version? On Dec 7, 2015 3:42 PM, "flypixel" notifications@github.com wrote:

Sorry I'm at work and fsharp is at home. But it seems that version of fsharp is 4.0.0.1, and of course I don't use Visual Studio (if you mean that by VS), because of

on Ubuntu

I use emacs if it can help, and also I run script with fsharpi with same results

Yeah I guess the issue is that we built against FSharp.Core.dll 4.4.xx On Dec 7, 2015 4:01 PM, "flypixel" notifications@github.com wrote:

OK, I'll check and write reply to you from home. Thanks.

Sorry again, but I checked the version of FSharp.Core and it is 4.4.0.0

Is there any solution to this? I have the same problem with referencing the paket.exe on OS X using Mono.

Edit: And on windows. I have installed the latest F# Tools 4.0 Bundle from Microsoft and VS 2015 Community. When I try to execute the referenced example in fsi, the aforementioned error occurs.

This is the error:

Ok, found a solution myself: Just reference the Paket.Core nuget package instead of the paket.exe.

[flypixel]

ok, thank you, I'll try

[realvictorprm]

I'm running into this too. Isn't there anything I can do to fix this?

[gusty]

For the record, this error happens in general when you are running from fsi a dll that was built with a higher version of FSharp.Core than the one that your fsi version supports.
