Question

我一时就坐下来了。我试图从我的可可申请中操作一条铁路,制造一条新闻铁路。一. 导言

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

我能够创建一个新的项目。但是,如果我这样作的话,我会这样做。

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

- (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];
}

我发现以下错误:

/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

我也存在同样的问题,因为我使用<代码>/bin/sh作为发射Path。

采用这一迅速的法典。

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()
