从 Python 脚本获取路径时，通过 Cygwin 使 Windows 路径在 RSync 中工作

问：

我正在尝试制作一个通过 Cygwin 与 RSync 交互的 Python GUI 应用程序。我已经完成了子进程，但由于路径与 Unix 不兼容，RSync 错误。

我知道路径应该被格式化为为了工作，这就是阻碍我的原因。我不知道有一种方法可以使路径以这样的格式获取，并且我尝试搜索它时无法在网上找到任何内容。/cygdrive/<drive letter>/<path>/<to>/<file or directory>/filedialog

我试图在路径字符串的前面附加（也许不是命令应该做的），但这什么也没做，当我期望它将字符串格式化为/cygdrive/os.path.join/cygdrive/<drive letter>/<path>/<to>/<file or directory>

我也尝试过使用 ，并将它们直接传递给子进程命令，但什么都没有（也可能是错误的命令，但这就是我的想法）os.path.relpathos.path.normpathsubprocess.run(["rsync", "-a" , os.path.relpath(<Source Path>)], os.path.relpath(<Destination Path>))

当前代码是这样的

import customtkinter
from tkinter import filedialog as fdiag
from tkinter import messagebox as mbox
import subprocess
import os

# Vars
global fdiagSrc, fdiagDest
fdiagDest = ''
fdiagSrc = ''

#Prepare Cygwin stuff
os.chdir(b"C:/cygwin64/bin/")
print(os.getcwd()) #Was checking if it was changing in the directory just in case

# Declare button stuff here first
def srcSel(): # Open a file dialog for Source directory selection, and assign that directory as a string  to a global var
    global fdiagSrc
    fdiagSrc = fdiag.askdirectory()
    while (len(fdiagSrc) == 0): # Show a warning in case user pressed "Cancel" or the close button on the dialog window and re-open the dialog
        mbox.showwarning("Warning!", "You did not select any directory for source!")
        fdiagSrc = fdiag.askdirectory()
    mbox.showinfo("Src", fdiagSrc)

def destSel(): # Open a file dialog for Destination directory selection, and assign that directory as a string  to a global var
    global fdiagDest
    fdiagDest = fdiag.askdirectory() # Show a warning in case user pressed "Cancel" or the close button on the dialog window and re-open the dialog
    while (len(fdiagDest) == 0):
        mbox.showwarning("Warning!", "You did not select any directory for destination!")
        fdiagDest = fdiag.askdirectory()
    mbox.showinfo("Dest", fdiagDest)

def GoToSendDir():
    if (len(fdiagDest) == 0) or (len(fdiagSrc) == 0): # Show a warning in case they didn't select any directories
        mbox.showwarning("Warning!", "You did not set any directories for Source and/or Destination! Please do that.")
    else: #Proceed to transfer/mirror/clone whatever it is called
        print(os.path.normpath(fdiagSrc)) # Checking the path if it is formatted properly..
        subprocess.run(["rsync", " -v -a ",os.path.normpath(fdiagSrc), os.path.normpath(fdiagDest)])
