我试图按照https://github.com/enricosada/fsharp-dotnet-cli-samples/wiki/Getting-Started#hello-world来开始使用我的mac上的f#和dotnet核心 .
% mkdir helloworld
% cd helloworld
% dotnet new --lang "f#"
Created new F# project in /Users/User/dotnet/helloworld.
% ls
Program.fs project.json
在这里,我已经可以说,没有NuGet.Config,如我所遵循的教程中所述 . 然后
% dotnet restore
log : Restoring packages for /Users/User/dotnet/helloworld/project.json...
log : Restoring packages for tool 'dotnet-compile-fsc' in /Users/User/dotnet/helloworld/project.json...
log : Writing lock file to disk. Path: /Users/User/dotnet/helloworld/project.lock.json

% dotnet run
Project helloworld (.NETCoreApp,Version=v1.1) will be compiled because expected outputs are missing
Compiling helloworld for .NETCoreApp,Version=v1.1

使用
dotnet new --lang "f#"
创建F#项目之前我遇到过类似的问题问题是这种依赖性,您应该在
project.json
file:dotnet-compile-fsc中看到 .在撰写本文时,这仅支持.Net Core 1.0 . *运行时,而不是您安装的.Net Core 1.1 . *运行时 .
要解决此问题,您可以install the .Net Core 1.0.* runtime from here并再次运行
dotnet run
. 1.1 . *和1.0 . *运行时都可以在本地安装而不会出现问题 .供参考,here is the issue reported on GitHub . 有一个修复,但它还没有在NuGet上 .
目前
dotnet-compile-fsc
还没有使用.NET Core 1.1(当前,sdk preview2.1),只能使用.NET Core 1.0(LTS,sdk preview2) .你可以使用dev feed来解决这个问题,如下所示:因为新的软件包还没有在nuget.org上
dotnet restore -f https://www.myget.org/F/netcorecli-fsc-preview2-1/api/v3/index.json
