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()

当我试图运行这个程序时，我错了“WindowsError：[错误2]系统找不到指定的文件：'tmp'”

Answer 1

os.chrdir(name)尝试访问'./tmp'，但您在'../tmp'

创建了目录

只需更新您的代码：

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

Answer 2

以下是您可以这样做的方法：

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()
