Question

我在AWS Lambda中使用googledrive凭据时出现问题，在我调用本地计算机上的函数之前部署我的.zip文件之后，一切正常，但是在约30分钟后我在AWS中部署zip我有lambda函数错误

  "errorMessage": "[Errno 30] Read-only file system: 'drive-python-quickstart.json'",
"errorType": "OSError",
  "stackTrace": [
    [
      "/var/task/lambda_function.py",
      33,
      "lambda_handler",
      "pageSize=10,fields=\"nextPageToken, files(id, name)\").execute()"
    ],
    [
      "/var/task/oauth2client/_helpers.py",
      133,
      "positional_wrapper",
      "return wrapped(*args, **kwargs)"
    ],
    [
      "/var/task/googleapiclient/http.py",
      835,
      "execute",
      "method=str(self.method), body=self.body, headers=self.headers)"
    ],
    [
      "/var/task/googleapiclient/http.py",
      162,
      "_retry_request",
      "resp, content = http.request(uri, method, *args, **kwargs)"
    ],
    [
      "/var/task/oauth2client/transport.py",
      186,
      "new_request",
      "credentials._refresh(orig_request_method)"
    ],
    [
      "/var/task/oauth2client/client.py",
      761,
      "_refresh",
      "self._do_refresh_request(http)"
    ],
    [
      "/var/task/oauth2client/client.py",
      802,
      "_do_refresh_request",
      "self.store.locked_put(self)"
    ],
    [
      "/var/task/oauth2client/file.py",
      79,
      "locked_put",
      "f = open(self._filename, 'w')"
    ]
  ]
}

在文件file.py中我有这段代码：

 def locked_put(self, credentials):
    """Write Credentials to file.
    Args:
        credentials: Credentials, the credentials to store.
    Raises:
        IOError if the file is a symbolic link.
    """
    self._create_file_if_needed()
    _helpers.validate_file(self._filename)
    f = open(self._filename, 'w')
    f.write(credentials.to_json())
    f.close()

def locked_delete(self):
    """Delete Credentials file.
    Args:
        credentials: Credentials, the credentials to store.
    """
    os.unlink(self._filename)

我尝试将f = open（self._filename，'w'）设置为'r'，但它没有帮助，也许谁知道我该如何修复它？请建议。

Answer 1

显然你正试图写一个不允许的文件。 Lambda目前仅支持将文件写入/ tmp目录。

Answer 2

我遇到了同样的错误 - 添加到@Tom Melo 的答案中，供其他仍在询问的人使用。由于错误试图写入您只能在 \tmp 文件夹中这样做的位置。

在我的情况下，将 .dat 文件的凭据复制到 tmp 并在 util.py 中使用相同的路径
我还想添加一个解决同样问题的github问题https://github.com/burnash/gspread/issues/623#issuecomment-548990924

AWS LAMBDA“errorMessage”：“[Errno 30]只读文件系统：'drive-python-quickstart.json'”
