Question

我已经用boto编写了一个结构脚本来在AWS实例上安装R应用程序。 Fedora 23

使用run＆amp; amp;的所有命令sudo功能按预期进行，

除了这一个：

@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＆＃39; warn_only = true＆＃39;，但这没有帮助。安装成功完成但没有错误，我通过登录实例和眼球 DvDdependencies.Rout 文件手动检查。我认为由于原因，我不知道R CMD BATCH命令不会将执行返回到结构。

来自Ctrl ^ c的回溯输出我本地系统上的结构进程是：

[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

完整的脚本位于我的github repo， DvDdependencies.R（我要安装的脚本）的位置

赞赏任何正确方向的评论，帮助或指示。

我正在关闭此问题，因为问题仅在于此脚本。 DvD工具的安装方法也已更新，因此不再感兴趣了。

R CMD BATCH script.R，通过fabric run（）执行永不退出
