更新 mono 后 F# 构建无法找到两个包

Question

我在 Linux 下有一个现有的 F#/Mono/paket/fake 项目，用于正确编译。

我使用 apt-get 更新了 mono，现在我的项目无法编译。

它找不到两个引用的包:MathNet.Numerics 和 Newtonsoft.Json。

这是我在构建项目时得到的结果:

Primary reference "MathNet.Numerics".
/usr/lib/mono/msbuild/15.0/bin/Microsoft.Common.CurrentVersion.targets(1980,5): warning MSB3245: Could not resolve this reference. Could not locate the assembly "MathNet.Numerics". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors.

          Considered "/usr/lib/mono/4.5-api/Facades/MathNet.Numerics.exe", but it didn't exist.
          For SearchPath "{GAC}".
          Considered "MathNet.Numerics", which was not found in the GAC.
          For SearchPath "{RawFileName}".
          Considered treating "MathNet.Numerics" as a file name, but it didn't exist.
          For SearchPath "/home/bleakcabal/Documents/projects/genesis/build/".
          Considered "/home/bleakcabal/Documents/projects/genesis/build/MathNet.Numerics.winmd", but it didn't exist.
          Considered "/home/bleakcabal/Documents/projects/genesis/build/MathNet.Numerics.dll", but it didn't exist.
          Considered "/home/bleakcabal/Documents/projects/genesis/build/MathNet.Numerics.exe", but it didn't exist.

该文件位于我的项目中的一个 packages 文件夹中(我使用 Ionide-fsharp 和使用 paket 和 fake 的 VS code 创建该文件夹)，但该文件夹没有出现在错误消息中。

我收到了与 Newtonsoft.Json 完全相同的消息。

这是我的 paket.dependency 文件:

source https://www.nuget.org/api/v2

nuget FAKE
nuget FSharp.Core
nuget MathNet.Numerics
nuget Newtonsoft.Json

我的 paket.lock 文件太长，无法发布，但以下是相关部分:

MathNet.Numerics (3.19)
      TaskParallelLibrary (>= 1.0.2856) - framework: net35

Newtonsoft.Json (10.0.2)
      Microsoft.CSharp (>= 4.3) - framework: netstandard10, >= netstandard13
      NETStandard.Library (>= 1.6.1) - framework: netstandard10, >= netstandard13
      System.ComponentModel.TypeConverter (>= 4.3) - framework: netstandard10, >= netstandard13
      System.Runtime.Serialization.Formatters (>= 4.3) - framework: >= netstandard13
      System.Runtime.Serialization.Primitives (>= 4.3) - framework: netstandard10, >= netstandard13
      System.Xml.XmlDocument (>= 4.3) - framework: >= netstandard13

以下是引用这些包的多个 .fsproj 文件之一的摘录:

...
<Reference Include="MathNet.Numerics" />
<Reference Include="Newtonsoft.Json" />
...

      <Private>True</Private>
      <Paket>True</Paket>
    </Reference>
  </ItemGroup>
</When>

如果我执行 mono --version 我会得到以下信息:

Mono JIT compiler version 5.0.1.1 (2017-02/5077205 Thu May 25 09:16:53 UTC 2017)

我尝试使用以下命令但无济于事:.paket/paket.exe Restore、.paket/paket.exe install、.paket/paket.exe 已过时。

Answer 1

要运行 paket，您需要运行

$ mono paket.exe install

如果您仍然遇到缺少程序集或不稳定引用的问题，请尝试

$ apt-get install mono-dev

或

$ apt-get install mono-complete
