与单音使用IronPython的奇怪的错误

在一些C＃代码中运行IronPython 2.7.7有一个奇怪的情况。

我的目标是编写一个能够将数据写入Excel电子表格的Mac OS程序。 数据只能在一个C＃库中打开的数据库中。

要导出电子表格，我有一个使用XLSXWriter的Python脚本，我通过IronPython从C＃代码调用。

我从C＃代码中调用了Python脚本，没有任何问题，脚本运行完美。 但是一旦脚本执行完毕，我在terminal中就会遇到一个SIGSEGV错误。 踢球者是电子表格打开完美。

这里是C＃代码：

var engine = Python.CreateEngine(); var libPath = engine.GetSearchPaths(); libPath.Add(Environment.GetFolderPath(Environment.SpecialFolder.Personal + "/Downloads/IronPython-2.7.7/Lib"); engine.SetSearchPaths(libPath); var scope = engine.CreateScope(); engine.ExecuteFile(Environment.GetFolderPath(Environment.SpecialFolder.Personal) + "/Downloads/ExcelScripts.py", scope); 

和我的Python脚本：

 import xlsxwriter import sys from os.path import expanduser home = expanduser("~") sys.path.append(home + "/.nuget/packages/ironpython/2.7.7/Lib") workbook = xlsxwriter.Workbook(home + "/Desktop/Output.xlsx") worksheet = workbook.add_worksheet() #Some simple example text worksheet.write('A1', 'Ticker') worksheet.write('B1', 'Company Name') worksheet.write('C1', 'Fiscal Year') worksheet.write('D1', 'Metric') workbook.close() 

最后，这里是我从terminal得到的输出：

我已经自己运行了Python脚本，没有错误。 我唯一的猜测是，IronPython试图使用Mono有一些冲突。 我已经安装了VS for Mac（Xamarin.Mac和iOS）。 任何帮助，将不胜感激。
