安装NuGet包NAudio.Lame 2.1.0报错：找不到该包，如何解决？

我在目标框架为.NETFramework,Version=v4.8的项目abc.Win中尝试安装NuGet包NAudio.Lame 2.1.0时，出现找不到包的错误。之前我成功安装过类似的NuGet包，希望解决该问题以顺利安装包，并让以下WAV转MP3的代码正常运行：

Shared Sub ConvertWAVtoMP3(inputWavPath As String, outputMp3Path As String)
    Using reader = New WaveFileReader(inputWavPath)

        Using writer = New LameMP3FileWriter(outputMp3Path, reader.WaveFormat, LAMEPreset.STANDARD)
            reader.CopyTo(writer)
        End Using
    End Using
End Sub

解决方案 #

• 添加官方NuGet源：当前NuGet仅在本地SDK源、DevExpress私有源中查找，缺少官方NuGet.org源。操作步骤：
  1. 打开Visual Studio，依次点击「工具」→「选项」→「NuGet包管理器」→「包源」
  2. 点击「+」新增源，名称设为「NuGet.org」，源地址填入https://api.nuget.org/v3/index.json
  3. 勾选新源确保启用
• 确认包信息正确性：验证NAudio.Lame包ID无误，且2.1.0版本确实存在（可在添加官方源后，通过NuGet包管理器搜索确认）
• 改用UI安装方式：如果命令行安装失败，可通过「项目」→「管理NuGet包」，搜索NAudio.Lame并选择2.1.0版本安装
• 清理NuGet缓存：执行命令dotnet nuget locals all --clear清除缓存后，重新尝试安装
