WindowsError：[错误2]系统找不到指定的文件：'tmp'

Question

import os 

def create_temporary_directory(path, name): 
    if not os.path.exists(os.path.join(path, name)): 
     os.mkdir(os.path.join(path, name)) 

if __name__ == "__main__": 
    name = 'tmp' 
    create_temporary_directory('..', name) 
    os.chdir(name) 

print os.getcwd() 

当我试图运行此程序，我错误“WindowsError：[错误2]系统找不到指定的文件： 'TMP'”

Answer 1

os.chrdir(name)试图达到'./tmp'，但你在'../tmp'

创建目录只需要更新您的代码的方式：

if __name__ == "__main__": 
    name = 'tmp' 
    create_temporary_directory('..', name) 
    os.chdir(os.path.join('..',name)) 

Answer 2

你可以这样做：

import os 

def create_temporary_directory(path, name): 
    if not os.path.exists(os.path.join(path, name)): 
     os.mkdir(os.path.join(path, name)) 
    return os.path.join(path, name) 

if __name__ == "__main__": 
    name = 'tmp' 
    path = create_temporary_directory('..', name) 
    os.chdir(path) 
    print os.getcwd()
