c# - Cannot find command 'dotnet ef'

Question

I am using .NET Core 2.0 on Arch Linux / Visual Studio Code and am trying to get EF tools to work, but I keep getting the error:

cannot find command dotnet ef

I've just about looked everywhere and none of the suggestions worked.

The result of running 'dotnet ef':

[wasiim@wasiim-PC WebApiServerApp]$ dotnet ef --help
Cannot find command 'dotnet ef', please run the following command to install

dotnet tool install --global dotnet-ef
[wasiim@wasiim-PC WebApiServerApp]$ dotnet tool list -g
Package Id            Version      Commands
---------------------------------------------------
dotnet-dev-certs      2.2.0        dotnet-dev-certs
dotnet-ef             2.2.3        dotnet-ef
[wasiim@wasiim-PC WebApiServerApp]$

This is the 'dotnet --info' result, if it's of help:

[wasiim@wasiim-PC WebApiServerApp]$ dotnet --info

This was the result of the above install command:
