System.ComponentModel.Win32Exception (2): An error occurred trying to start process 'dotnet' with working directory

[golesmn]

When I use the ui tool for creating migrations and updating the db it says System.ComponentModel.Win32Exception (2): An error occurred trying to start process 'dotnet' with working directory.It works when I execute the same command from the terminal. I am currently on ubuntu 22.04

To Reproduce

Steps to reproduce the behavior:

1. Go to UI tools ''
2. Click on Update or Add migrations

Expected behavior

I wanted the migrations to run or make migrations but it is not happening using the tool but I can do that from the terminal

Screenshots

Environment :

• OS: Ubuntu 22.04

• .NET SDK info (installed ones and version used within Rider): 6.0.408

• Plugin version: 232.0.0-rc1

• Rider version: 2023.2

Hi @golesmn , thanks for the ticket. Please share your dialog setup before executing the command. Also, please uncheck "No build" checkbox, it should not be used unintentionally.

[seclerp]

And also please share your solution layout. Where your .csproj files are located?

and the popup is like this

When you click "Preview", which "Working directory" is shown?

working directory is correct. It is same as the working directory where the csproj and solution are located.

[seclerp]

Hi folks, please add as many details about your cases as possible. Thank you.

@Prohor327 if your question is about dotnet ef in general and not about Rider, please forward it to .NET team.

Terminal command works normally

[seclerp]

Rider executes dotnet ef commands quite close to how they would be executed via the terminal. The main difference that may cause issues is environment on which Rider executable is running. It may have different $PATH and other variables defined.

So I suggest performing 2 checks:

1. Environment comparison

Please check your $PATH and other variables in your terminal profile and compare them to the Rider ones. Also, check for symlinks, according to the similar issue on efcore tooling side: dotnet/efcore#16071

To validate which environment is used by Rider:

1. Find the "IDE Scripting Console" in Search Everywhere (Shift, Shift)
2. Type there System.getenv("PATH")
3. Press Ctrl/Cmd + Enter

More information about IDE Scripting Console could be found here.

2. dotnet executable layout

Also, from Exec format error I can also suggest that for some reason dotnet executabe which is used by inner dotnet ef command may have unsupported process architecture. If you have ARM-based Apple chip please validate that your env in Rider uses an ARM version of the dotnet and vice versa in case of Intel chip.

In case it doesn't help you are welcome to report the issue to our issue tracker with full logs collected. The simplest way of doing it is a Help | Report a Bug option from the application menu. Please provide detailed steps to reproduce the issue. Thanks!

Also having the same issue, but it seems that only dotnet-ef is on my path, but dotnet is'nt, how do we change the path on the IDE scripting console?

[ChekeGT]

Created a symlink on /usr/local/bin cause that path was already registered on IDE scripting console. But i dont like the solution at all
