R CMD BATCH script.R ，通过 fabric 运行() 执行永远不会退出

Question

我用 boto 编写了一个 fabric 脚本来在 AWS 实例上安装 R 应用程序。软呢帽 23

所有使用运行和 sudo 功能的命令都按预期执行，

除了这个：

@parallel
def install_DvD():
#       with settings(hide('warnings', 'running', 'stdout', 'stderr'), warn_only=True):
             cmd0 = 'R CMD BATCH %s/DvDdependencies.R' % (DvDpackage_location)
             run(cmd0)

如您所见，我尝试使用 'warn_only=true'，但没有帮助。安装成功完成，没有错误，我通过登录实例并查看 DvDdependencies.Rout 文件手动检查。我认为出于我不了解的原因，R CMD BATCH 命令不会 return 执行返回结构。

在我的本地系统上 Ctrl^c 结构进程的回溯输出是：

[ec2-54-172-154-181.compute-1.amazonaws.com] run: R CMD BATCH ~/DvDdependencies.R
[ec2-54-165-109-62.compute-1.amazonaws.com] run: R CMD BATCH ~/DvDdependencies.R


^C

完整的脚本在我的github repo， DvDdependencies.R（我要安装的脚本）的位置

任何意见、帮助或正确方向的指示都将不胜感激。

我正在关闭它，因为问题只出在这个脚本上。还更新了 DVD 工具的安装方法，因此这不再令人感兴趣了。
