Question

我正在尝试进入我的软件包管理器控制台，它给了我以下错误：

An error occurred while reading file 'C:\Users\rein.shope\Documents\Visual Studio 2015\Projects\Vidly\Vidly\packages.config': Null or empty package id

错误显示在窗口顶部的功能区中（“恢复”按钮在单击时不执行任何操作）和窗口内的红色文本。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Id字段似乎都完好无损。 Google搜索不会为“null或空包ID”返回任何内容。

Answer 1

尝试将所有Id更改为id（小写）。它为我解决了。

Answer 2

我还不能发表评论，所以我将为这个帖子的未来访问者写一个答案。我有同样的错误消息，但是问题是文件中的id更改为ids。我把它改回来，它也为我解决了这个问题。

Answer 3

我遇到了同样的问题，奇怪的是，这是packages.config发生的事情

<?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d个字母都会变成MovieID 我认为这是一个错误，我正在使用VS community 2019最新版本您可以手动修复

Answer 4

我猜这是由于 resharper 或一些类似的工具造成的。最初，我重命名了变量名，然后 resharper 将其应用于项目中的所有文件，甚至是 packages.config。所以最好照顾好这个功能:)

重命名回 id 解决了这个问题

packages.config：空包或空包
