Cannot install anything using dotnet tool install command

I'm trying to install the dotnet-ef tool via the dotnet-cli.

The command that I enter: dotnet tool install --global dotnet-ef

It gives me the following error:

   C:\Users\%USERNAME%\AppData\Local\Temp\147383a8-b714-4336-bb96-30c0670ea37d\restore.csproj : error NU1211: Project res
tore must have a single package reference(s).
C:\Users\abby.rahimi\AppData\Local\Temp\147383a8-b714-4336-bb96-30c0670ea37d\restore.csproj : error NU1212: Invalid pro
ject-package combination for Microsoft.DotNet.Analyzers.Compatibility 0.2.12-alpha. DotnetToolReference project style c
an only contain references of the DotnetTool type
The tool package could not be restored.
Tool 'dotnet-ef' failed to install. This failure may have been caused by:

* You are attempting to install a preview release and did not use the --version option to specify the version.
* A package by this name was found, but it was not a .NET tool.
* The required NuGet feed cannot be accessed, perhaps because of an Internet connection problem.
* You mistyped the name of the tool.

its not just about ef, I cant install any other tool.

I tried specifying version, still not working I tried a bunch of things:

I have an acces to https://api.nuget.org/v3/index.json so it's not the problem with my internet connection.

Had a similar issue in Azure DevOps build pipelines. My fix was adding packageSourceMapping to nuget.config in my repo root dir.

To ensure that the dotnet tool install works when installing tools available on nuget.org, you can configure nuget.config with the packageSourceMapping feature. This feature ensures that packages with specific prefixes are only searched in designated feeds, avoiding conflicts or unnecessary searches in private feeds.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <!-- Clear any inherited sources -->
    <clear />
    <!-- Add public NuGet feed -->
    <add key="nuget" value="https://api.nuget.org/v3/index.json" />
    <!-- Add private feed -->
    <add key="privatefeed" value="https://example.pkgs.visualstudio.com/_packaging/Private/nuget/v3/index.json" />
  </packageSources>
  <packageSourceMapping>
    <!-- Map public NuGet feed to all packages -->
    <packageSource key="nuget">
      <package pattern="*" />
    </packageSource>
    <!-- Map private feed to specific namespace prefix -->
    <packageSource key="privatefeed">
      <package pattern="YourPrivateNamespace.*" />
    </packageSource>
  </packageSourceMapping>
</configuration>

I had a similar issue. What fixed it for me was removing the <packageSourceMapping> tag in %appdata%\Nuget\NuGet.Config.

it looks like dotnet tool iterates the nuget.config sources and when one fails, it doesn't continue with next ones.

In my case, it was failing because I have a private feed, which needs authentication (despite that configured in nuget.config).

Thanks to @wli3 who mentioned use of: --ignore-failed-sources like this:

dotnet tool install -g nbgv --ignore-failed-sources

Which did helped. Original link: https://github.com/dotnet/sdk/issues/16215#issuecomment-791796542

One thing to check is if the main NuGet source is configured with the dotnet SDK. Normally it should have the https://api.nuget.org/v3/index.json source by default, but maybe something went wrong, and the source list got messed up.

First thing to check is what source(s) are configured on your installation, by running the following command line:

dotnet nuget list source

If you do NOT see the source for the standard https://api.nuget.org/v3/index.json path, you can add it back in with the following command line:

dotnet nuget add source https://api.nuget.org/v3/index.json -n nuget.org

Note: You can name the source anything you want with the -n switch.

Another thing to check is if the source is disabled. If so, you can re-enable it with the following command:

dotnet nuget enable source nuget.org
