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 .NET Core SDK (reflecting any global.json):  Version:   2.2.105  Commit:    7cecb35b92  Runtime Environment:  OS Name:     arch  OS Version:  OS Platform: Linux  RID:         arch-x64  Base Path:   /opt/dotnet/sdk/2.2.105/  Host (useful for support):   Version: 2.2.3   Commit:  6b8ad509b6  .NET Core SDKs installed:   2.2.105 [/opt/dotnet/sdk]  .NET Core runtimes installed:   Microsoft.NETCore.App 2.2.3 [/opt/dotnet/shared/Microsoft.NETCore.App]  To install additional .NET Core runtimes or SDKs:   https://aka.ms/dotnet-download

Answer 1

In my case, the tools folder didn't exist inside %USERPROFILE%\.dotnet\ so I had to run the command dotnet tool install --global dotnet-ef to install dotnet ef. Then I was able to run dotnet ef...

This was the result of the above install command:
