У меня есть два компьютера с, казалось бы, одинаковым кодом и конфигурациями, один компилирует решение, другой нет.
Проблема связана с R Type Provider.
Это код:
/// Path to project data folder.
[<Literal>]
let projDataPath = __SOURCE_DIRECTORY__ + @"\data\"
[<Literal>]
let jsonPath = projDataPath + "fractal.json"
type PathInfo = JsonProvider<Sample=jsonPath>
/// Csv provider for files with information about assets
type AssetsInfo = CsvProvider<Sample="AssetInfoFS.csv", // must be a Literal
HasHeaders=true,
ResolutionFolder=projDataPath,
AssumeMissingValues=false,
CacheRows=false>
[<Literal>]
let configPath = projDataPath + "config.json"
type Cnfg = JsonProvider<Sample=configPath>
На обоих компьютерах работает Windows 10, на одном из которых код не компилируется, работает версия Home, на другом -Pro версия.
На обоих компьютерах установлено Visual Studio Community 2017 Version 15.7.2.
Конфигурация
Приложение:
Целевая среда F #: 4.4.3.0
Целевая структура: .NET Framework 4.6.1
Тип вывода: Console Application
Сборка:
Платформа Цель: Any CPU
Другие флаги: Prefer 32-bit
Установленные пакеты:
R.NET Community v1.65
R.NET Community,FSharp v1.65
RProvider v1.1.2.0
R версия:
Пробовал с R 3.4.3 и R 3.5.0, в обоих случаях 32-Битовые и 64-битные версии были установлены.
Сообщение об ошибке:
parse error FS3053: error : The type provider constructor has thrown an exception: Initialization of R.NET failed
1>FSC: warning FS3005: Referenced assembly 'C:\Projects\bitbucket3\VSProjects\Fractal13\packages\RProvider.1.1.20\lib\net40\RProvider.dll' has assembly level attribute 'Microsoft.FSharp.Core.CompilerServices.TypeProviderAssemblyAttribute' but no public type provider classes were found
1>Done building project "Fractal13.fsproj" -- FAILED.
В Интернете и в SO были некоторые старые вопросы, связанные с этим, но не яснорешение.Любые предложения по решению этой проблемы?
