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:

Possible reasons for this include: * You misspelled a built-in dotnet command. * You intended to execute a . NET program, but dotnet-ef does not exist. * You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH.
Use dotnet tool update --global dotnet-ef to update the global tools to the latest available version. If you have the tools installed locally in your project use dotnet tool update dotnet-ef . Install a specific version by appending --version <VERSION> to your command.
dotnet ef can also be used as a local tool. To use it as a local tool, restore the dependencies of a project that declares it as a tooling dependency using a tool manifest file. To update the tools, use the dotnet tool update command.
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
