Can not install Sitecore.CLI for Sitecore 10

Sitecore Asked by Nikola Kramaric on February 21, 2021

I am following the guide specified here. I can successfully run the command dotnet new tool-manifest however I get an error when I run

dotnet tool install Sitecore.CLI --add-source


C:Program Filesdotnetsdk3.1.405NuGet.targets(128,5): error : Failed to retrieve information about 'sitecore.cli' from remote source ''sitecore.cli'&semVerLevel=2.0.0'. [***]
C:Program Filesdotnetsdk3.1.405NuGet.targets(128,5): error :   The content at ''sitecore.cli'&semVerLevel=2.0.0' is not valid XML. [**]
C:Program Filesdotnetsdk3.1.405NuGet.targets(128,5): error :   For security reasons DTD is prohibited in this XML document. To enable DTD processing set the DtdProcessing property on XmlReaderSettings to Parse and pass the settings into XmlReader.Create method. [***]
The tool package could not be restored.
Tool 'sitecore.cli' failed to install. This failure may have been caused by:

* You are attempting to install a preview release and did not use the --version option to specify the version.
* A package by this name was found, but it was not a .NET Core tool.
* The required NuGet feed cannot be accessed, perhaps because of an Internet connection problem.
* You mistyped the name of the tool.

Any ideas?

One Answer

I found the fix to this. In Visual Studio 2017 or 2019:

Navigate to Tools > NuGet Package Manager > Package Manager Settings > Package Sources and remove the reference to Sitecore NuGet. This was there from a previous setup of Sitecore. My theory is that it conflicted with this installation.
