Question

我在CentOS上安装了dotnet核心，还有一个使用JWT的项目

https://www.nuget.org/packages/JWT/3.1.1

我的OSX本地恢复效果非常好：

dotnet --info
.NET Command Line Tools (2.0.3)

Product Information:
Version:            2.0.3
Commit SHA-1 hash:  eb1d5ee318

Runtime Environment:

OS Platform: Darwin

Microsoft .NET Core Shared Framework Host

Version  : 2.0.3

服务器：

dotnet --info
.NET Command Line Tools (2.0.3)

Product Information:
Version:            2.0.3
Commit SHA-1 hash:  c85173f757

Microsoft .NET Core Shared Framework Host

Version  : 2.0.3
Build    : N/A

但是在服务器上它不起作用：

dotnet add package JWT --version 3.1.1
Writing /tmp/tmphdc0Ux.tmp
error: Unable to load the service index for source 
https://api.nuget.org/v3/index.json.
error:   The type initializer for 'System.Net.Http.CurlHandler' threw an exception.
error:   The type initializer for 'Http' threw an exception.
error:   The type initializer for 'HttpInitializer' threw an exception.
error:   Unable to load DLL 'System.Net.Http.Native': The specified module or one of its dependencies could not be found.
error:    (Exception from HRESULT: 0x8007007E)

dotnet安装命令：

yum install centos-release-dotnet
yum install rh-dotnet20

我尝试了dotnet clean，并尝试将软件包版本更改为更新或更旧，没有任何作用。我的.csproj中的其他软件包已成功恢复，任何建议都将非常受欢迎。

如果不满足.NET Core的某些本机先决条件，则会发生此错误。在这种情况下，libcurl要么不存在，要么安装了不兼容的版本

查阅Prerequisites for .NET Core on Linux文档并确保使用最新版本（当前使用2.0.3的.NET Core Sdk 2.1.4）
