nuget does not recognize my project

Question

nuget does not recognize my project

Cliff Gold 0

I am using Visual Studio 17.7.1. I changed which distribution of Python I was using, From Anaconda to Python.org. Now, I can't get any packages via nuget. I have tried:

Creating a new project.
Updating the nuget json file.
Logging on as Admin

The nuget console does not show any projects in the pulldown. The error I get is Project 'Default' is not found. And the project name pulldown is empty. I have not tried a full uninstall - reinstall of Visual Studio, but that is my next option.

Hi @Cliff Gold ,

Welcome to Microsoft Q&A!

What is your project type? How did you change the distribution of Python from Anaconda to Python.org?

What command are you using when getting the error: Project 'Default' is not found?

Please update your VS2022 to the latest version with Visual Studio Installer.

Then, launch VS > open the project > go to Solution Explorer > right-click on project node > Set as Startup Project.

Then, check that the “Default project” drop-down displays properly.

Sincerely,

Anna

Anna,

Thanks for the quick reply. Unfortunately, your suggestion did not work. I'm not sure what you mean by "with the Visual Studio Installer". I used Help/Check for Updates. Updated me from 17.7.1 to 17.7.2. I set the default startup, and dropdown still blank.

Project Type is Python, if that's what you are looking for. If I go to Project/Properties, first thing I see is "Application"

I downloaded and installed from Python.org. Then, I used the env dropdown to select 3.11. I also switched in the Interactive window. I expect I screwed up something when I did this.

The command I used was install-package Numpy. Here is the complete error message:

Install-Package : Project 'Default' is not found. At line:1 char:1 + Install-Package Numpy + ~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : ObjectNotFound: (Default:String) [Install-Package], ItemNotFoundException + FullyQualifiedErrorId : NuGetProjectNotFound,NuGet.PackageManagement.PowerShellCmdlets.InstallPackageCommand PM>

Hello, I mean that you can update the VS by opening Visual Studio Installer from the start menu.

Have you check it in a new project? Does it persist?

Yes, I did try it on a new project. It did persist. I will re-try that today. I will also try an uninstall/reinstall today.

Okay, did a bunch of uninstall/reinstalls. Ended up with Anaconda3. NuGet still doesn't work, but I don't need it with the Anaconda3. The packages I need come preinstalled.

Hello, if it is a Python project, you can’t use the Package Manager Console to install Numpy package.

Please try to open the Python Environments windows and install the package using pip.

For more information, please refer to: Install packages in your Python environment.

Ah, I see. That was not clear anywhere I found. I'm using Anaconda3 for now, and will try that if I need to change.
