如何从可可应用程序运行rails命令？ [英] How do you run the rails command from a cocoa application?

问题描述

我一直呆在这一段时间。我试图运行一个rails shell命令从我的可可应用程序创建一个新闻栏应用程序。当我运行

I've been stuck on this one for a while. I'm trying to run a rails shell command from my cocoa application to create a news rails app. When I run

~/.rvm/gems/ruby-1.9.3-p194/gems/railties-3.2.3/bin/rails new projectname

我可以创建一个新项目。但是如果我运行这样

I'm able to create a new project. But if I run something like this

NSString *path = @"~/.rvm/gems/ruby-1.9.3-p194/gems/railties-3.2.3/bin/rails";
NSString *script = [NSString stringWithFormat:@"%@ new ~/Desktop/testapp", path];
system([script UTF8String]);

或此

- (IBAction)buildProject:(NSButton *)sender 
{
NSString *path = @"~/.rvm/gems/ruby-1.9.3-p194/gems/railties-3.2.3/bin/rails";
NSArray *args = [NSArray arrayWithObjects:@"new", @"~/Desktop/testapp", nil];

NSTask *task = [NSTask new];
[task setLaunchPath:path];
[task setArguments:args];
[task launch];
}

我收到以下错误

/Users/dylanross/.rvm/gems/ruby-1.9.3-p194/gems/railties-3.2.3/bin/rails:7:in `require': no such file to load -- rails/cli (LoadError)
from /Users/dylanross/.rvm/gems/ruby-1.9.3-p194/gems/railties-3.2.3/bin/rails:7

推荐答案

我有一个类似的问题，因为我使用 / bin / sh 作为launchPath。

I had a similar problem because I was using /bin/sh as launchPath.

尝试这个swift代码。

Try this swift code.

let task = NSTask()
task.launchPath = "/bin/bash"
let fileToRun = "/Users/johndoe/Desktop/testapp/app.rb"
task.arguments = ["-l", "rvm-auto-ruby", fileToRun]
let pipe = NSPipe()
task.standardOutput = pipe
task.launch()
