我在Xenial和Trusty Ubuntu的Travis CI上遇到Mono 5.14.0.177，msbuild 15.0，nuget 4.7.1的构建失败，但在VirtualBox，Ubuntu Xenial中无法重现。
运行后:mono tools/nuget/nuget.exe restore pythonnet.sln -o packages
错误消息是:
Currently running NuGet.exe 4.1.0.
Updating NuGet.exe to 4.7.1.
Update successful.
MSBuild auto-detection: using msbuild version '15.0' from '/usr/lib/mono/msbuild/15.0/bin'.

这是在VirtualBox中成功构建的代码:

并在Travis CI中构建失败:

最佳答案
通过降级到msbuild 14.0，此问题已在pythonnet Travis CI中得到临时解决:
cmd = "{0} update -self".format(nuget)
self.debug_print("Updating NuGet: {0}".format(cmd))
subprocess.check_call(cmd, shell=use_shell)
cmd = "{0} restore pythonnet.sln -MSBuildVersion 14 -o packages".format(nuget)

关于c# - 在Travis CI上使用Mono 5.14.0.177，msbuild 15.0，nuget 4.7.1构建失败，但在VirtualBox中不可复制，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/51988395/
