我目前正在使用 Python 3.8 和 Tcl/Tk 8.6 開(kāi)發(fā) MacOs Catalina 10.15.6。正如此處所建議的，我從https://sourceforge.net/projects/tkdnd/下載了 Tk 擴(kuò)展tkdnd2.8 ，并從https://sourceforge.net/projects/tkinterdnd/下載了 Python 包裝器TkinterDnD2，然后復(fù)制將 tkdnd2.8目錄復(fù)制到/Library/Tcl，將TkinterDnD2目錄復(fù)制到/Library/Frameworks/Python.framework/Versions/.../lib/python/site-packages。之后，當(dāng)嘗試執(zhí)行以下簡(jiǎn)單代碼時(shí)：from TkinterDnD2 import *import tkinter as tkroot = TkinterDnD.Tk()它給了我錯(cuò)誤：Traceback (most recent call last):    File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/TkinterDnD2/TkinterDnD.py", line 39, in _require        TkdndVersion = tkroot.tk.call('package', 'require', 'tkdnd')_tkinter.TclError: can't find package tkdndDuring handling of the above exception, another exception occurred:Traceback (most recent call last):    File "/Users/Administrador/Desktop/tkdnd_test.py", line 3, in <module>        root = TkinterDnD.Tk()    File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/TkinterDnD2/TkinterDnD.py", line 271, in __init__        self.TkdndVersion = _require(self)    File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/TkinterDnD2/TkinterDnD.py", line 41, in _require        raise RuntimeError('Unable to load tkdnd library.')RuntimeError: Unable to load tkdnd library.由于 tkdnd 不會(huì)自動(dòng)找到/加載（將 tkdnd2.8 文件夾重命名為 tkdnd 也不起作用），我嘗試按照 @Ellis Shen 和 @aong152 的建議手動(dòng)指定庫(kù)路徑。我將tkdnd2.8文件夾復(fù)制到tkdnd_test.py文件旁邊。不幸的是，當(dāng)運(yùn)行以下代碼時(shí)：from TkinterDnD2 import *import tkinter as tkimport sys, osprint(os.environ.get('TKDND_LIBRARY'))application_path = os.path.dirname(os.path.abspath(__file__))TK_DND_PATH = os.path.join(application_path,'tkdnd2.8')os.environ['TKDND_LIBRARY'] = TK_DND_PATHprint(os.environ.get('TKDND_LIBRARY'))root = TkinterDnD.Tk()我覺(jué)得我在這里遺漏了一些東西，但我花了很多時(shí)間搜索類似的經(jīng)歷，但未能找到解決方案。任何幫助都感激不盡。
