尝试在eclipse中配置python解释器时，在通过cygwin shell创建的virtualenv中使用python失败

Question

以下是日志中的错误，我试图配置解释器，但失败了。有人能帮忙解释一下这个错误吗？这是一台公司机器，所以我没有管理员权限。Cygwin安装了--no-admin选项，Eclipse是独立版。

环境详细信息：windows8cygwin：（最新）Eclipse:Version:Neon。2版本（4.6.2）构建id:20161208-0600 Python:Python 3.4。5（默认，2016年10月10日，14:41:48）[GCC 5.4.0]基于cygwin java版本“1.8.0_66”java（TM）SE运行时环境（构建1.8.0_66-b18）java热点（TM）64位服务器虚拟机（构建25.66-b18，混合模式）

尝试执行Python安装中的测试Python命令，例如“Python--version”，以查看Python是否执行良好。就我而言，一个windows库丢失了。
