ValueError: Client secrets must be for a web or installed app
我正在运行Python Quickstart下的quickstart.py示例代码，并且遇到以下错误：
ValueError: 客户端密钥必须用于网络或安装的应用程序。
我创建了一个具有项目所有者权限的credentials.json文件。
错误发生在以下代码段中：
if os.path.exists('token.pickle'):
with open('token.pickle', 'rb') as token:
creds = pickle.load(token)
# 如果没有有效的凭据可用，让用户登录。
if not creds or not creds.valid:
if creds and creds.expired and creds.refresh_token:
creds.refresh(Request())
else:
flow = InstalledAppFlow.from_client_secrets_file('credentials.json', SCOPES)
creds = flow.run_local_server()
# 保存凭据以供下次运行使用
with open('token.pickle', 'wb') as token:
pickle.dump(creds, token)
我还注意到token.pickle文件没有被创建。这是错误输出：
