pants - 裤子二进制命令失败是不可翻译的错误

Question

我使用的是裤子版本 1.15.0

./pants binary在以下步骤中运行命令时

12:23:05 00:01   [native-compile]
12:23:05 00:01     [conan-prep]
12:33:30 10:26       [create-conan-pex]

我收到以下错误：

Exception message: Package SourcePackage(u'file:///Users/guperera/roku-workspace/data-processing/.pants.d/python-setup/resolved_requirements/CPython-2.7.16/PyYAML-3.13.tar.gz') is not translateable by ChainedTranslator(WheelTranslator, EggTranslator, SourceTranslator)

我怎样才能解决这个问题？

谢谢！
