打開攪拌機（程序）從一個特定的文件路徑，相對路徑，Unix的可執行

Question

在我剛纔的問題，Open a file from a specific program from python，我發現瞭如何使用子爲了打開一個程序（攪拌機）—好，特定.blend文件—從具有此代碼的特定文件路徑。

import os 
import subprocess 

path = os.getcwd() 
os.system("cd path/") 
subprocess.check_call(["open", "-a", os.path.join(path, "blender.app"),"Import_mhx.blend"]) 

隨着the help of a guy at a forum，我想用.blend文件中的相對路徑，所以我以這種方式（適用於Windows）

import os 
import subprocess 

# This should be the full path to your Blender executable. 
blenderPath = "/cygdrive/c/Program Files/Blender Foundation/blender-2.62-release-windows32/blender.exe" 

# This is the directory that you want to be your "current" directory when Blender starts 
path1 = "/Users/user/Desktop/scenario/Blender" 

# This makes makes it so your script is currently based at "path1" 
os.chdir(path1) 

subprocess.check_call([blenderPath, "Import_mhx.blend"]) 

，併爲Mac改變了代碼，

import os 
import subprocess 

path = os.getcwd() 
os.system("cd path/") 
print (path) 
# This should be the full path to your Blender executable. 
blenderPath = path + "/blender.app/Contents/macos/blender" 

# This is the directory that you want to be your "current" directory when Blender starts 
path1 = "/Users/user/Desktop/scenario/Blender" 

# This makes makes it so your script is currently based at "path1" 
os.chdir(path1) 

subprocess.check_call([blenderPath, "Import_mhx.blend"]) 

結果：

1. 在Windows中，它工作正常。
2. 在Mac上，結果是文件已打開，但程序似乎未打開。我認爲這很奇怪。

問題：

1. 有，我應該爲了地方攪拌機（UNIX可執行文件）才能打開任何延期？
2. 有沒有其他方法可以做到這一點，以便正確打開程序，但也能夠使用.blend文件內的相對路徑？

Answer 1

import os 
import subprocess 

blenderPath = "./blender.app/Contents/MacOS/blender" 

path1 = "./" 

os.chdir(path1) 

subprocess.check_call([ blenderPath, "Animation.blend"]) 

兩個攪拌機打開完美，.blend文件工作確定內部相對路徑:)
