我使用脚本 
#!/usr/bin/expect -f
# auto-select.exp

spawn npm start

expect "Select proxy source:" 
exp_send "Sending up arrow twice and enter\n"
send "\x1B\[A\x1B\[A\r"  # Simulate up arrow key
# send "^[OA\033[A\r"  # 将 `[` 转义  # Simulate up arrow key


expect "Enter the path to your proxy.txt file"
exp_send "Sending enter\n"
send "\r"  # Simulate up arrow key

expect eof


结果报错
