我在MonoDevelop下建立了一个简单的项目，并可以从那里成功地运行测试(*)。
当我尝试从命令行使用nunit-console.exe时，我会得到以下结果：
.../mono2/bin/Debug$ nunit-console mono2.exe
NUnit version 2.5.10.0
...
Runtime Environment -
OS Version: Unix 2.6.32.44
CLR Version: 2.0.50727.1433 ( 2.10.8.1 (Debian 2.10.8.1-1~dhx1~lucid1) )
ProcessModel: Default DomainUsage: Single
Execution Runtime: Default
Unhandled Exception:
System.ArgumentException: NUnit components for version 4.0.30319 of the CLR are not installed
...
如果我省略了重要的内容，请告诉我。
nunit-gui给出了相同的错误。nunit-gui有一个选项可以从2.0切换到4.0，但是当我尝试时，它再次给出相同的错误，因此不允许我更改它。
更多细节：Ubuntu 10.04，使用http://badgerports.org/lucid.html存储库，因此是Mono 2.10.8.1。
根据MonoDevelop中的项目选项，该项目设置为使用"Mono/.NET 4.0"。

also need to redirect system assemblies in the test config file,

*: 嗯，当我尝试使用更奇特的Nunit属性时，我遇到了问题；这是我试图解决的真正的问题，它导致了我上面描述的那个问题。然而，上面使用的exe只有两个简单的测试，在MonoDevelop中运行良好。
