使用subprocess.run在Windows

Question

運行過程中，我希望通過Python運行下面很長的shell命令：

C:/Users/Alex/Desktop/tableexporter/WGTableExporter.exe "E:/Steam (Games Installed Directly to Hard Drive)/steamapps/common/Wargame Red Dragon/Data/WARGAME/PC/430000626/NDF_Win.dat" pc\ndf\patchable\gfx\everything.ndfbin TAmmunition 

當我運行這個作爲，從Windows外殼程序，它按預期工作。

但是，當我試圖通過Python的subprocess.run做同樣的事情時，它不喜歡它。這是我輸入：

import subprocess 
comm = [r'C:/Users/Alex/Desktop/tableexporter/WGTableExporter.exe "E:/Steam (Games Installed Directly to Hard Drive)/steamapps/common/Wargame Red Dragon/Data/WARGAME/PC/430000626/NDF_Win.dat" pc\ndf\patchable\gfx\everything.ndfbin TAmmunition'] 
subprocess.run(comm, shell=True) 

這裏是我的輸出：

The directory name is invalid. 
Out[5]: CompletedProcess(args=['C:/Users/Alex/Desktop/tableexporter/WGTableExporter.exe "E:/Steam (Games Installed Directly to Hard Drive)/steamapps/common/Wargame Red Dragon/Data/WARGAME/PC/430000626/NDF_Win.dat" pc\\ndf\\patchable\\gfx\\everything.ndfbin TAmmunition'], returncode=1) 

爲什麼會發生這種情況？

Answer 1

間距錯了。子進程正在等待一系列參數，它將爲你正確地分配空間。

comm = ['C:/Users/Alex/Desktop/tableexporter/WGTableExporter.exe','E:/Steam (Games Installed Directly to Hard Drive)/steamapps/common/Wargame Red Dragon/Data/WARGAME/PC/430000626/NDF_Win.dat','pc\ndf\patchable\gfx\everything.ndfbin','TAmmunition'] 

你所得到的錯誤的原因是因爲周圍E中的雙引號的：/蒸汽... 它寫這樣的一個shell：

c:/users/alex/desktop/tableexporter/wgtableexporter.exe \"E:/Steam (Games Installed Directly to Hard Drive)/steamapps/common/Wargame Red Dragon/Data/WARGAME/PC/430000626/NDF_Win.dat\" pc\ndf\patchable\gfx\everything.ndfbin TAmmunition 

Answer 2

的間距不正確，但是使用os.system()將不會要求您更改間距。

這應該工作：

import os 
os.system("""C:/Users/Alex/Desktop/tableexporter/WGTableExporter.exe  "E:/Steam (Games Installed Directly to Hard Drive)/steamapps/common/Wargame Red Dragon/Data/WARGAME/PC/430000626/NDF_Win.dat" pc\ndf\patchable\gfx\everything.ndfbin TAmmunition""") 

但是，如果你想使用子（這是更好）

import subprocess 
comm = ['C:/Users/Alex/Desktop/tableexporter/WGTableExporter.exe','E:/Steam (Games Installed Directly to Hard Drive)/steamapps/common/Wargame Red Dragon/Data/WARGAME/PC/430000626/NDF_Win.dat','pc\ndf\patchable\gfx\everything.ndfbin TAmmunition'] 
subprocess.run(comm, shell=True)
