I had same problem too this command works for me

npm i autoprefixer@latest

It automatically added need dependency in package.json and package-lock.json file like below:

As mentioned in Scott Kuhl's answer this issue is mentioned in https://github.com/madskristensen/WebCompiler/issues/413

For me, running the command npm i caniuse-lite- browserslist only worked for about 1/2 a day before it was an issue again.

The following solution, mentioned in the post, works much better. This updates the node.js file so that it uses console.log instead of console.warn when returning these errors.

You can manually update this file located at C:\Users\[Username]\AppData\Local\Temp\WebCompiler[VersionNumber]\node_modules\browserslist

Or, so that it is done automatically, add the following to your .csproj file by:

1. Right click on project file and select "Unload Project"
2. Edit the .csproj file
3. Paste the following into the project file. I pasted it towards the end of the file, before the </Project> end tag and before the build web compiler package was imported.

    <ItemGroup>
        <PackageReference Include="MSBuildTasks" Version="1.5.0.235">
            <PrivateAssets>all</PrivateAssets>
            <IncludeAssets>runtime; build; native; contentfiles; analyzers</IncludeAssets>
        </PackageReference>
    </ItemGroup>
    <PropertyGroup>
        <TempFolder>$([System.IO.Path]::GetTempPath())</TempFolder>
    </PropertyGroup>
    <ItemGroup>
        <BrowsersListNodeJsFiles Include="$(TempFolder)\WebCompiler*\node_modules\browserslist\node.js" />
    </ItemGroup>
    <Target Name="BrowsersListWarningsAsInfo" BeforeTargets="WebCompile">
        <FileUpdate Files="@(BrowsersListNodeJsFiles)"
                    Regex="console.warn"
                    ReplacementText="console.log" />
    </Target>

4. Reload the project back into the solution.
