R CMD批处理script.R，通过fabric run()执行永不退出

Question

我已经用boto编写了一个fabric脚本来在AWS实例上安装一个R应用程序。软呢帽23

所有使用run & sudo函数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)

正如您所注意到的，我尝试使用‘warn=true’，但这并没有帮助。安装成功完成，没有出现错误，我通过登录到实例并监视DvDdependencies.Rout文件来手动检查。我认为由于一些原因，R批处理命令不会将执行返回到fabric。

来自Ctrl^c的跟踪输出在我的本地系统上的织物过程是：

[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

完整的脚本在我的github回购中，DvDdependencies.R的位置(我想安装的脚本)。

任何正确方向的评论、帮助或指示都将受到欢迎。

我要结束这个问题，因为问题只是这个脚本。此外，DvD工具的安装方法已经更新，因此这已经不再有意义了。
