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

我已经用boto编写了一个fabric脚本，用于在AWS实例上安装R应用程序。软呢帽23

所有使用run&sudo函数的命令都按预期运行

除此之外：

@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)

正如您所注意到的，我尝试使用“warn_only=true”，但没有任何帮助。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。 我认为由于我不知道的原因，R CMD BATCH命令不会将执行返回到fabric

本地系统上结构进程的Ctrl^c回溯输出为：

[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

完整的脚本在我的， （我要安装的脚本）的位置

任何正确方向的评论、帮助或指点都将不胜感激。

我将结束此讨论，因为问题仅限于此脚本。 此外，DvD工具的安装方法也已更新，

因此，这不再令人感兴趣。

因此，当您手动运行

R CMD BATCH/DvDdependencies.R

时，您会得到提示返回，但通过fabric您不会得到提示。。。有趣的是，手动测试了该命令，它可以工作并退出。除此之外，我还有$R CMD INSTALL package.tar.gz命令，它们也可以正常工作。
