Question

我创建了一个svg2png.command文件，它只是启动一个python文件。它以这种方式调用python文件：

shell1 = './scripts/cairosvg.py ../projects/%s/wip/skin/%s/screenLayout/staticScreens/%s -o ../projects/%s/wip/skin/%s/screenLayout/staticScreens/%s' % (projectName, projectName, filename, projectName, projectName, filename[:-4]+".png")
os.system(shell1)

python文件cairosvg.py导入模块（cairo）。它看起来像：

import cairosvg
cairosvg.main()

当我双击svg2png.command文件时，一切都按预期进行，并且从svg文件创建了一个png文件。好。

然后我尝试从OSX Swift应用程序启动命令：

let task = NSTask()
task.launchPath = "svg2png.command"
task.arguments = ""
task.launch()
task.waitUntilExit()

我已经使用更简单的python脚本多次完成了这些操作，并且它们都按预期工作。但是在那种情况下，我收到错误：

"Traceback (most recent call last):", "  File \"scripts/svg2png.py\", line 4, in <module>", "    import cairo", "ImportError: No module named cairo", "s"

为什么双击.command时可以找到这个cairo模块，但是从Swift启动时却找不到？此外，解决这个问题的方法很棒。

他们肯定是不同的，任何想法？

从Swift启动时找不到python模块
