Question

尝试在macOS High Sierra上构建一个简单的F＃项目时出错。

$ mono --version
Mono JIT compiler version 5.0.1.1 (2017-02/5077205 Sun Sep 17 18:29:46 BST 2017)
Copyright (C) 2002-2014 Novell, Inc, Xamarin Inc and Contributors. www.mono-project.com
    TLS:           normal
    SIGSEGV:       altstack
    Notification:  kqueue
    Architecture:  amd64
    Disabled:      none
    Misc:          softdebug 
    LLVM:          supported, not enabled.
    GC:            sgen (concurrent by default)

步骤：

打开VS代码
Ionide New F＃Project
选择Suave项目模板
$ mono .paket/paket.exe install
$ ./build.sh

错误是：

我怎样才能使这个工作？

Answer 1

Ionide默认没有选择正确的目标框架。

您需要进行以下更改：

要*.fsproj，请将目标框架更改为：

<TargetFramework>netcoreapp2.0</TargetFramework>

要paket.dependencies，请将框架更改为：
```
framework: >= netcoreapp2.0
```

再次运行Paket：

$ mono .paket/paket.exe install

再次运行构建脚本：

$ ./build.sh

在macOS上使用F＃ - 伪造无法构建
