Question

我正在使用Capistrano在Slicehost上部署rails应用程序。部署过程的一部分涉及重建gem并安装它。

通过git scm将代码部署到服务器上运行正常，但出于某种原因我尝试做了...

run 'gem build /my/app/folder/my.gemspec'

...在deploy.rb中的一个单独的任务中，它都是bboom。我收到一个奇怪的错误，告诉我gemspec中的文件不是文件...

ERROR:  While executing gem ... (Gem::InvalidSpecificationException)
[ ... , "public/images/admin/navigation_shadow.png", "public/images/admin/new_layout.png", "public/images/admin/buttons_background.png", "public/images/admin/expand.png", "public/images/admin/status_spinner

这很奇怪，因为当我进入盒子并手动完成时，同样的命令可以正常工作，当我这样做时......

sh -c 'gem build /my/app/folder/my.gemspec'

这是capistrano包装远程命令行调用的方式，当我手动执行时也能正常工作。

甚至尝试在另一个ruby文件中调用Kernel.system（）并从deploy.rb调用它，但仍然遇到同样的问题。疯狂。

想知道它是否与

有关

** [out :: MY.IP.A.DRES]

以明显随机的间隔添加到输出中的字符串。

“工作正常”可能并不完全正确，你确定它不会输出STDERR吗？

out :: IP addr的东西有点奇怪，不正常;你还应该考虑你的PATH是否设置正确，这是PTY和TTY之间的区别。

最简单的方法（但不完美）是：

run('echo $PATH')

与

ssh my.server.addr 'sh -c \'echo $PATH\''

（后者就是Cap，实际上是。）

您可能还想尝试：

run("cd /my/app/folder/ && gem build my.gemspec")

^其中一个适合你。
