There was a problem while setting up the environment

I'm just starting with dotnet so I have no idea what I should do to be able to install it

My issue is that my dotnet version is 6.0.101 so the issue is that there is no /usr/local/share/dotnet/packs/Microsoft.NETCore.App.Ref/6.0.0/ref/net6.0. I do have /usr/local/share/dotnet/packs/Microsoft.NETCore.App.Ref/6.0.1/ref/net6.0/ but I don't know how to tell FAKE to look for it.

I tried adding the proper path in FAKE_SDK_RESOLVER_CUSTOM_DOTNET_PATH (with FAKE_SDK_RESOLVER_CUSTOM_DOTNET_PATH="/usr/share/dotnet:$FAKE_SDK_RESOLVER_CUSTOM_DOTNET_PATH") and even ln -s /usr/share/dotnet /usr/local/share/dotnet but it doesn't work.

Welcome to the FAKE community! Thank you so much for creating your first issue and therefore improving the project!

[yazeedobaid]

can you please send the output of dotnet --info and try with the new 5.21.1 release?

[mattiasdrp]

I don't know anything about F# ecosystem, how should I build the 5.21.1 release?

[baronfel]

@mattiasdrp you can update your version with dotnet tool update fake-cli to update to 5.21.1, the latest stable version.

[mattiasdrp]

@mattiasdrp can you please check your environment variables? Specifically PATH, DOTNET_HOST_PATH, DOTNET_ROOT, and DOTNET_ROOT(x86)? Do you see an entry with /usr/bin/dotnet?

The default locations for linux is /usr/share/dotnet/ and mac is /usr/local/share/dotnet? But the resolved path from logs is usr/bin/packs/Microsoft.NETCore.App.Ref/6.0.0/ref/net6.0

And in the resolution algorithm, we look for environment variables before default installation. So maybe you have an entry in one of these environment variables that got resolved by algorithm.

[mattiasdrp]

Sure!

❯ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/lib/wsl/lib

❯ printenv | grep "DOTNET"

The default locations for linux is /usr/share/dotnet/ and mac is /usr/local/share/dotnet? But the resolved path from logs is usr/bin/packs/Microsoft.NETCore.App.Ref/6.0.0/ref/net6.0

My issue is that my dotnet version is 6.0.101 so there is no /usr/local/share/dotnet/packs/Microsoft.NETCore.App.Ref/6.0.0/ref/net6.0. whereas there is /usr/local/share/dotnet/packs/Microsoft.NETCore.App.Ref/6.0.1/ref/net6.0/, can it be related to that?

[yazeedobaid]

Can you please check if you have this path in your file system? usr/bin/packs/Microsoft.NETCore.App.Ref/6.0.0/ref/net6.0 Or if you have at least dotnet host in usr/bin?

[mattiasdrp]

I have dotnet in usr/bin:

❯ la /usr/bin/dotnet
lrwxrwxrwx 1 root root 22 Nov 17 19:53 /usr/bin/dotnet -> ../share/dotnet/dotnet

I don't have usr/bin/packs/Microsoft.NETCore.App.Ref/6.0.0/ref/net6.0

[yazeedobaid]

@mattiasdrp You have a symlink from usr/bin to share/dotnet. In the algorithm, we use to resolve reference assemblies we don't follow symlinks. Can you please remove the symlink and try? Because from dotnet --info output, SDKs are installed in usr/share/dotnet which is the original path in symlink

cc: @baronfel

[baronfel]

Correct, if dotnet is a symlink the symlink should be followed to its root before doing the directory probing algorithm.

[mattiasdrp]

Hi, thanks for your answer ;-)

Build failing again. Once again it tries to find /usr/share/dotnet/packs/Microsoft.NETCore.App.Ref/6.0.0/ref/net6.0 when it should find /usr/share/dotnet/packs/Microsoft.NETCore.App.Ref/6.0.1/ref/net6.0 (6.0.0 instead of 6.0.1).

Not sure if this is related but what helped in my case was setting the framework to net6.0 in my paket.dependencies file:

group Build

source https://api.nuget.org/v3/index.json
storage: none
framework: net6.0

nuget FSharp.Core
nuget Fake.Core.Target
nuget Fake.IO.FileSystem
nuget Fake.JavaScript.Yarn
nuget Fake.DotNet.Cli
nuget Fake.IO.Zip
nuget Fake.Tools.Git
nuget CliWrap
nuget FSharp.Control.Reactive

before it was netstandard2.0 and I was getting similar problems. Oh, and your global.json really needs to be on point as well.

Ran into this issue on Ubuntu 20.04 with dotnet SDK 6.0.200.

How to reproduce

First create a skeleton project. I've found it needs some actual source code to run into this issue, but that could be anecdotal since I tried many different things.

mkdir fake-test
cd fake-test
dotnet new fake # Yes/Yes when prompted
dotnet tool install paket
mkdir proj
dotnet new console --language F# --output proj
dotnet fake build

Everything up until this point works as expected. Here's where the fun begins. If the folder is copied (or cloned as a git repo), and built with a fresh terminal, this error pops up. Let's assume I copied fake-test over to fake-test-2:

# Fresh terminal
cd fake-test-2
rm -rf .fake
dotnet fake build

Result:

There was a problem while setting up the environment:
-> Could not find referenced assemblies in path: '/usr/bin/packs/Microsoft.NETCore.App.Ref/6.0.2/ref/net6.0', please check installed SDK and runtime versions

Workaround

This seems to fix the issue in the local environment only:

export DOTNET_HOST_PATH=/usr/share/dotnet/sdk

I'm trying to build Fable on Debian with .NET 6.0.202 and encountered a similar problem.

It turned out Fable was not using FAKE (😅). But FAKE failed before trying to run build.fsx as a FAKE script, so this is still relevant.

It seems like there are two separate issues going on, but one seems to be already fixed in release/next and the other seems to be a duplicate.

I think this issue may be safe to close?

1. FAKE tries to find the .NET SDK installation from dotnet, but fails because /usr/bin/dotnet is a symlink and FAKE doesn't follow it

You would see /usr/bin/packs/ in the error when this happens:

There was a problem while setting up the environment:
-> Could not find referenced assemblies in path: '/usr/bin/packs/Microsoft.NETCore.App.Ref/6.0.0/ref/net6.0', please check installed SDK and runtime versions`

This seems to be already fixed in https://github.com/fsprojects/FAKE/commit/aad29e66660c3b36f4dd092c402a198d4ac97a8f, which adds a code to follow symlink when FAKE uses the location of dotnet to get the .NET root.

The export DOTNET_HOST_PATH (or export DOTNET_ROOT) workaround fixes this because FAKE does not need to resolve .NET root and skips the above code entirely.

2. FAKE assumes the host version is 6.0.0, which causes problem on newer hosts

You would see /usr/share/dotnet in the error when this happens:

There was a problem while setting up the environment:
-> Could not find referenced assemblies in path: '/usr/share/dotnet/packs/Microsoft.NETCore.App.Ref/6.0.0/ref/net6.0', please check installed SDK and runtime versions

I think this is actually a duplicate of the scenario 3 of #2641.

I tried removing global.json in Fable and I'm now seeing a different error, which is because build.fsx is actually not a FAKE script and is my bad.

Some says export DOTNET_HOST_PATH alone fixes this problem, but I assume they are using global.json with the exact .NET version, or does not use global.json in their project at all.

I'm also getting this, but only on Linux. On Windows it works. Removing global.json makes it work on Linux as well. Not sure why, I tried using 6.0.100 and 6.0.202 in global.json, but the error didn't go away until I removed the globa.json file.

[gaven]

If you're experiencing this issue on a Mac with a M1 processor (assuming you've installed the x64 version of the .NET SDK). You'll need to create an environment variable named DOTNET_HOST_PATH and set it's value to /usr/local/share/dotnet/x64/sdk.

[thinkbeforecoding]

Had the same problem. adding framework: net6.0 in the #r "paket: ..." and removing the global.json fixed it.

[kant2002]

I fix my issue with building FSharp.Data by removing global.json It's content was

{
  "sdk": {
    "version": "6.0.203",
    "rollForward": "major"
  }
