我正在制作一个自动化本地开发工作流程的Applescript。发生的事情是我在检查脚本依赖性（即MAMP）时使用Applescript进度条运行。进度条出现，动画完美，并返回我的例程，按预期检查依赖项。问题是，即使进度条达到其总步数，进度条也会冻结，即使脚本在以下例程中调用对话框，并且脚本冻结。
以下是启动进度条的例程：
on dependency_check()
set progress description to "Access Granted: "
set progress additional description to "Preparing..."
delay 0.5
set progress total steps to 100
repeat with i from 0 to 100
try
if i = 0 then
set progress additional description to "Checking Dependencies..."
delay 0.5
else if (i > 0 and i < 10) then
set progress additional description to "Checking Node.js..."
else if i = 10 then
set progress additional description to node_exists()
else if (i > 10 and i ≤ 20) then
set progress additional description to "Node.js is installed..."
else if (i > 20 and i < 30) then
set progress additional description to "Checking mamp-cli..."
else if i = 30 then
set progress additional description to mampcli_exists()
else if (i > 30 and i ≤ 40) then
set progress additional description to "mamp-cli is installed..."
else if (i > 40 and i < 50) then
set progress additional description to "Checking MAMP..."
else if i = 50 then
set progress additional description to mamp_exists()
else if (i > 50 and i ≤ 60) then
set progress additional description to "MAMP is installed..."
else if (i > 60 and i < 70) then
set progress additional description to "Checking Google Chrome..."
else if i = 70 then
set progress additional description to chrome_exists()
else if (i > 70 and i ≤ 80) then
set progress additional description to "Google Chrome is installed..."
else if (i > 80 and i < 100) then
set progress additional description to "All Dependencies Found..."
else if i = 100 then
set progress additional description to "Complete..."
set progress completed steps to i
end if
set progress completed steps to i
delay 0.025
on error errTxt number errNum -- errTxt and errNum are returned from system
display dialog errTxt & return & errNum
exit repeat
end try
end repeat
end dependency_check
应该注意的是，它在i = 10,30,50,70时调用其他例程。
如果找到依赖关系，它们都会返回文本。
以下是其中一个例程的示例：
on node_exists()
set nodeExists to do shell script "test -e /usr/local/bin/node"
if nodeExists is not "" then -- Verifies Node.js is installed by 'test' command
beep
tell application "Finder" to display dialog ¬
"Node.js is not installed, and is needed to run this program. Download Node.js and try again." with title ¬
"Required Library Missing: Node.js!" with icon caution ¬
buttons {"Download Node.js", "Quit Program"} ¬
default button 2 cancel button 2
if button returned of result is "Download Node.js" then
open location "https://nodejs.org/en/"
script_exit()
end if
else
return "Node.js is installed..."
end if
end node_exists
提前感谢您的帮助。我完全卡住了！
