Python 临时文件 [Errno 66] 目录不为空

Question

我需要处理从 db 对象生成的一些文件，并且在所需的过程之后需要删除该目录和文件。我决定使用 python Templefile 包。我已经尝试过但坚持了下来Direcotry not Empty [ Error 66 ].

在views.py中

def writeFiles(request, name):
    tmpdir = tempfile.mkdtemp()
    instance = request.user.instances.get(name=name)
    print(instance)
    print(instance.name)
    code = instance.serverFile
    jsonFile = instance.jsonPackageFile
    docker = """
    FROM node
    # Create app directory
    RUN mkdir -p /usr/src/app
    WORKDIR /usr/src/ap

    # Install app dependencies
    COPY package.json /usr/src/app/
    RUN npm install

    # Bundle app source
    COPY . /usr/src/app

    EXPOSE 8080
    CMD [ "node", "server" ]"""
    # Ensure the file is read/write by the creator only
    saved_umask = os.umask(0o077)
    server = 'server.js'
    json = 'package.json'
    path = os.path.join(tmpdir)
    print(path)
    try:
        with open(path + '/dockerfile', "w") as dockerfile:
            dockerfile.write(docker)
        with open(path + '/server.js', "w") as server:
            server.write(code)
        with open(path + 'package.json', "w") as json:
            json.write(jsonFile)
        print(os.path.join(tmpdir, json))
    except IOError as e:
        print('IOError:', e)
    else:
        os.remove(path)
    finally:
        os.umask(saved_umask)
        os.rmdir(tmpdir)

Answer 1

我只是注意到path = os.path.join(tmpdir)使得path等于tmpdir。也就是说，当目录不为空时，os.remove或 都os.rmdir不起作用。

这些是操作系统调用，不会递归到目录中包含的文件。

所以只需使用

import shutil
shutil.rmtree(tmpdir)
