[SOLVED] Cannot install dotnet-ef tool on Windows 10

Issue

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

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

I gives me the following error:

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 Core tool.
* The required NuGet feed cannot be accessed, perhaps because of an Internet connection problem.
* You mistyped the name of the tool.

I’m using dotnet 3.0, I believe I didn’t have this problem on MacOS, I’m now trying to execute the same command on my Windows 10 machine and it gives me that error.

Some info using dotnet --info command:

Solution

I got it working by adding the --version flag and specifying the version to 3.0.0.

The command that I used:

dotnet tool install --global dotnet-ef --version 3.0.0
