好的，我现在已经把这个问题倾倒了20次了，这让我感到困惑。我正在为Citra Emu的“金丝雀”版本编写一个非官方的更新程序。起初一切都顺利完成，应用程序运行良好，但它严重依赖带有硬编码路径的Bash脚本。我想让它们更具动态性，以便在多台机器/ macOS版本之间轻松安装和维护。
我认为最好的选择是将剩余的代码转换为Applescript，并且只在必要时通过do shell script进行Bash调用。现在大部分都有效。该程序构建正常，但它似乎由于单独的语法错误而失败，并且在此处看不见。这是代码（请原谅这个混乱。）：

if the button returned of the result is "Update" then
tell application "System Events" to write "DoUpdate" to file (path to resource "update/ShoudUpdate" in bundle (path to application "Citra"))

现在我意识到这是处理进度条的一种相当多余和草率的方式，但请保持你的判断，因为手头的问题更加有趣。尝试直接运行此脚本时，它返回：
“运行Shell脚本”操作遇到错误：“1533：1534：语法错误：预期”“”但发现未知令牌。（ - 2741）“
我会坦率地说，我没有丝毫知道 1533：1534：部分是什么，我从来没有能够分辨出这部分Applescript错误代码代表什么鉴于它的结构类似于指向发生错误的行和列的C调试器，但显然这个脚本中肯定没有1500行。
这似乎是一个标准的语法错误，但是我已经阅读了整个脚本，就像我说的那样，20次，我只是无法找到导致此语法错误的原因。它在脚本编辑器中构建良好，但尝试运行它会导致上述错误，与保存和运行应用程序包或Bash脚本相同。
更重要的是，Xcode中突出显示的Bash语法或脚本编辑器中突出显示的Applescript语法都没有引起我的注意。事实上，根据他们的语法突出显示一切都很好。
如果有人可以帮我弄清楚这个脚本的哪个部分被破坏了，我们将不胜感激。在这一点上，我正试图解决这个问题。
