Scaffolding: No executable found matching command "dotnet-aspnet-codegenerator"

[pitrackster]

Describe the bug

At this point of the tutorial : https://docs.microsoft.com/en-us/aspnet/core/tutorials/razor-pages/model?view=aspnetcore-3.0&tabs=visual-studio-code#scaffold-the-movie-model we are asked to install the dotnet-aspnet-codegenerator tool. There is no problem installing it but as soon as I try to execute the command dotnet aspnet-codegenerator razorpage -m Movie -dc RazorPagesMovieContext -udl -outDir Pages/Movies --referenceScriptLibraries I've got this error in terminal : Aucun exécutable ne correspond à la commande "dotnet-aspnet-codegenerator"

I have try everything found on other issues that seems similar but most of them are related to version 2.2.0... and wont work :(

To Reproduce

Steps to reproduce the behavior:

1. Using this version of ASP.NET Core '2.2.104'
2. (Follow the tutorial until you are asked to) Run this code dotnet aspnet-codegenerator razorpage
3. With these arguments -m Movie -dc RazorPagesMovieContext -udl -outDir Pages/Movies --referenceScriptLibraries
4. See error : Aucun exécutable ne correspond à la commande "dotnet-aspnet-codegenerator"

Expected behavior

In my opinion it should generate the proper views ;-)

Additional context

Using zsh instead of bash, no idea if this can help...

A little update if it can help...
As stated here calling the dotnet-aspnet-codegenerator command from within the installation folder works :

• cd /home/me/.dotnet/tools/
• ./dotnet-aspnet-codegenerator -h

Scaffolding failed.
Could not find project file in /home/me/.dotnet/tools

Hi !
Below is the content of my RazorPageMovie.csproj file

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>
    <AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>
  </PropertyGroup>


  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.App" />
    <PackageReference Include="Microsoft.AspNetCore.Razor.Design" Version="2.2.0" PrivateAssets="All" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="2.2.2" />

Can you update the version of CodeGenerator.Design to 2.2.3. Also, can you confirm if this works from Visual Studio?

<PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="2.2.2" />

[pitrackster]

I'll check if it works with the updated version as soon as possible. But as I use Linux I wont be able to tell if it works from VisualStudio.

[pitrackster]

Hi. Just updated the version of CodeGenerator to 2.2.3 but it does not solve the issue.

[pitrackster]

Tried to do it again from scratch and still have the same error ... quite disappointing...

@seancpeters - Any idea why it would fail to find the code generator from commanline?

Aucun exécutable ne correspond à la commande "dotnet-aspnet-codegenerator"

/cc @wli3

[wli3]

It could be the shell. What shell are you using? We global tools currently can only automatically add PATH to bash. And could you show us the $PATH? Is /home/me/.dotnet/tools/ in it?

[pitrackster]

@wli3 Hi !

I am using zsh instead of bash so this might be the problem !
And in fact .dotnet/tools is not in the $PATH variable...

Could you please provide me the PATH I should add to my .zshrc ?
Thanks

[wli3]

$HOME/.dotnet/tools is what you need to add to path

export PATH=$PATH:$HOME/.dotnet/tools

[pitrackster]

@wli3 works like a charm !

Thanks everyone !

[vijayrkn]

Thanks guys!

[ViniciusRio]

$HOME/.dotnet/tools is what you need to add to path

export PATH=$PATH:$HOME/.dotnet/tools

Thanks! <3
