packages.config：包ID为空或不存在。

Question

我试图进入我的程序包管理器控制台，但是它给了我以下错误：

“在读取文件'C：\ Users \ rein.shope \ Documents \ Visual Studio 2015 \ Projects \ Vidly \ Vidly \ packages.config'时发生错误：空软件包ID”

该错误显示在窗口顶部的一个带有“还原”按钮的功能区中（单击无效），并以红色文字显示在窗口内。控制台不允许我输入命令。

“packages.config”的内容：

<?xml version="1.0" encoding="utf-8"?>

</packages>

所有的Id字段似乎完好无损。Google搜索未返回“null或空包ID”的内容。

尝试将所有的Id改为小写的id。这对我有用。

我遇到了同样的问题，奇怪的是这就是发生在packages.config上的情况。

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package MovieID="Antlr" version="3.5.0.2" targetFramework="net472" />
  <package MovieID="bootstrap" version="3.4.1" targetFramework="net472" />
  <package MovieID="jQuery" version="3.3.1" targetFramework="net472" />
  <package MovieID="jQuery.ValiMovieIDation" version="1.17.0" targetFramework="net472" />
  <package MovieID="Microsoft.AspNet.Mvc" version="5.2.7" targetFramework="net472" />
  <package MovieID="Microsoft.AspNet.Razor" version="3.2.7" targetFramework="net472" />
  <package MovieID="Microsoft.AspNet.Web.Optimization" version="1.1.3" targetFramework="net472" />
  <package MovieID="Microsoft.AspNet.WebPages" version="3.2.7" targetFramework="net472" />
  <package MovieID="Microsoft.CodeDom.ProvMovieIDers.DotNetCompilerPlatform" version="2.0.0" targetFramework="net472" />
  <package MovieID="Microsoft.jQuery.Unobtrusive.ValaMovieIDation" version="3.2.11" targetFramework="net472" />
  <package MovieID="Microsoft.Web.Infrastructure" version="1.0.0.0" targetFramework="net472" />
  <package MovieID="Modernizr" version="2.8.3" targetFramework="net472" />
  <package MovieID="Newtonsoft.Json" version="11.0.1" targetFramework="net472" />
  <package MovieID="WebGrease" version="1.6.0" targetFramework="net472" />
</packages>

请注意所有的 d 字母都会变成 MovieID 我认为这是一个 bug，我正在使用最新版本的 VS Community 2019 你可以手动修复它。

Answer 3

我猜这是由于resharper或类似工具引起的。最初，我重命名了变量名称，resharper将其应用于项目中的所有文件，甚至是packages.config。 因此最好注意一下这个功能 :)

将名称改回id解决了这个问题
