【问题描述】：
我正在尝试在 Amazon Linux 映像上安装 Nuget。我的目标是对支持 .netcore 的 AWS .NET SDK 进行一些研究。
我已经尝试了三种（每次尝试都是新实例）主要安装方法。
1 - 安装 .netcore，然后从源代码编译 Nuget。
我按照here 的指示成功安装了 .netcore，尽管我修改了（我的更改以粗体显示）如何使用这些步骤对路径的更新进行持久化：
# sudo yum install libunwind libicu -y
# curl -sSL -o dotnet.tar.gz https://go.microsoft.com/fwlink/?LinkID=835019
# sudo mkdir -p /opt/dotnet && sudo tar zxf dotnet.tar.gz -C /opt/dotnet
**# echo 'pathmunge /opt/dotnet' > /etc/profile.d/dotnetcore.sh**
**# chmod +x /etc/profile.d/dotnetcore.sh**
**# . /etc/profile**
然后我从这里https://github.com/NuGet/NuGet.Client 克隆了 Nuget 代码并运行 build.sh，它成功完成但没有创建带有 Nuget 可执行文件的工件子目录。此方法仅用于安装 NuGet CLI - 而不是包管理器 - 但两者均未安装。根据此站点，Linux 仅支持 CLI：https://docs.nuget.org/ndocs/guides/install-nuget（“NuGet CLI 是适用于 Windows、Mac OS X 和 Linux 的命令行实用程序，支持所有 NuGet 功能。”）
2 - 安装 Mono 并运行“yum install nuget”
我通过执行以下步骤成功安装了 Mono：
# sudo yum -y install cmake bison gettext glib2 freetype fontconfig libpng
libpng-devel libX11 libX11-devel glib2-devel libexif glibc-devel
urw-fonts java
unzip gcc gcc-c++ automake autoconf libtool make bzip2 wget
# cd /usr/local/src
# sudo wget http://download.mono-project.com/sources/mono/mono-4.8.0.382.tar.bz2
# sudo tar jxf mono-4.8.0.382.tar.bz2
# cd mono-4.8.0
# sudo ./configure --prefix=/opt/mono
# sudo make
# sudo make install
安装和测试 mono 后，我使用以下命令添加了一些存储库：
# rpm --import "http://keyserver.ubuntu.com/pks/lookup?op=get&search=0x3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF"
# yum-config-manager --add-repo http://download.mono-project.com/repo/centos/
# yum-config-manager --add-repo http://download.mono-project.com/repo/centos-nightly/
运行yum install nuget命令时收到依赖错误，结果：

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
我尝试使用 --skip-broken 命令重新安装，但 nuget 没有安装。
此时我尝试通过从此处http://www.libpng.org/pub/png/libpng.html构建最新的 Libpng 代码来手动更新 Libpng 包
此时我开始达到我 linux 能力的极限。我能够成功地构建 libpng 与
./configure
make
make install
但我不确定更新的库或者我现在是否有两个版本的 libpng。我不确定如何查看 Yum 正在使用哪个版本。
3 - 安装 .net core 然后运行“yum install nuget”
我得到了与尝试 #2 完全相同的错误。
【问题讨论】：
-
如果您使用 .NET Core，那么
dotnet restore是包装 NuGet 还原操作的方式。如果您使用 Mono，请停止从源代码构建，因为您还不知道它是如何工作的。 Mono 项目主页清楚地显示了如何从 Xamarin repo 安装二进制文件，但您需要找到一台干净的机器才能在此阶段开始。
