我使用 launchctl 来启动我的 py 代码的守护进程：
launchctl load -w com.bruce2.PicUploaderHelper.plist
然后我ps aux | grep testpynput启动了守护进程：
root 65334 0.1 0.2 4350320 37596 ?? Ss 2:52 0:00.44 /usr/local/Cellar/python/3.7.2/Frameworks/Python.framework/Versions/3.7/Resources/Python.app/Contents/MacOS/Python /Users/bruce/PicUploaderHelper-macOS/testpynput.py /Users/bruce/PicUploaderHelper-macOS/config2.json
但是键绑定不起作用，但是如果我在 iTerm2（macOS 上的终端应用程序）中使用完全相同的代码，它就可以工作，我的意思是我直接在 iTerm2 中执行以下代码：
/usr/local/Cellar/python/3.7.2/Frameworks/Python.framework/Versions/3.7/Resources/Python.app/Contents/MacOS/Python /Users/bruce/PicUploaderHelper-macOS/testpynput.py /Users/bruce/PicUploaderHelper-macOS/config2.json
pynput
我意识到 macOS 有一些限制macOS 的限制，其实我一开始并没有将 iTerm2 添加到System Preferences→<code>Security & Privacy→<code>Accessibility，即使我testpynput.py直接在 iTerm2 上执行也不起作用，但是在我将 iTerm2 添加到之后Accessibility，这种方式可以正常工作：
所以我把
/usr/local/Cellar/python/3.7.2/Frameworks/Python.framework/Versions/3.7/Resources/Python.app
或者
/usr/local/Cellar/python/3.7.2/Frameworks/Python.framework/Versions/3.7/Resources/Python.app/Contents/MacOS/Python
到 System System Preferences→<code>Security & Privacy→<code>Accessibility，这就像我把 iTerm2 放到 Accessibility 对吧？，但两者都不起作用。
那么，你们知道我该如何解决这个问题吗？
我会把我的代码放在这里：

放入com.bruce2.PicUploaderHelper.plist，/Library/LaunchAgents确保您需要将其所有者设置为root:wheel
-rw-r--r-- 1 root wheel 894B 3 22 14:41 com.bruce2.PicUploaderHelper.plist
然后通过 sudo 或 root 权限运行：
sudo launchctl load -w com.bruce2.PicUploaderHelper.plist
这是文件中的代码： PicUploaderHelper-macOS.zip
Python2.7也是一样，我试过了。
macOS：10.14.1 (18B75)
python2：Python 2.7.15
python3：Python 3.7.2
iTerm2：3.2.7
