英文:

GCP: Creating Client() object locally

问题

以下是翻译好的部分：

我有这个用于日志记录到 StackDriver 的类。

```python
from google.cloud.logging.handlers import CloudLoggingHandler
from google.oauth2 import service_account

class GoogleLogger(CloudLoggingHandler):

    CREDS = google.cloud.logging.Client(
        project=PROJECT, credentials=service_account.Credentials.from_service_account_file("/path/to/creds"))

    def __init__(self, client=CREDS):
        super(GoogleLogger, self).__init__(client)

当在 Google 云上运行时，这个类可以无缝运行。但是，在本地运行时，它会在 CREDS = google.cloud.logging.Client(project=PROJECT, credentials=service_account.Credentials.from_service_account_file("/path/to/creds")) 处中断，并且我的整个代码都会崩溃。

问题： 是否有办法在不在云上运行时跳过实例化这个类？比如条件类？

或者

问题： 是否有办法让这个在本地运行？它应该可以运行。我已经提供了凭据和项目，根据StackDriver文档，如果我提供了项目和凭据，它应该可以在本地和GCP上运行？

当出现问题时，以下是回溯信息：

Traceback (most recent call last):

    class GoogleLogger(CloudLoggingHandler):

I have this class which is used for logging to StackDriver.

from google.cloud.logging.handlers import CloudLoggingHandler
from google.oauth2 import service_account

class GoogleLogger(CloudLoggingHandler):

CREDS = google.cloud.logging.Client(
    project=PROJECT, credentials=service_account.Credentials.from_service_account_file("/path/to/creds"))

def __init__(self, client=CREDS):
    super(GoogleLogger, self).__init__(client)

When run on the google cloud, this works seamlessly. However, when run locally it breaks at `CREDS = google.cloud.logging.Client(project=PROJECT, credentials=service_account.Credentials.from_service_account_file("/path/to/creds"))` 

And my entire code breaks. 

**Question:** Is there any way to skip instantiating this class if not on the cloud? Like a conditional class? 

*OR*

**Question:** Is there any way to make this work locally? It should work. I give it the creds and the project and according to [StackDriver docs](https://cloud.google.com/logging/docs/setup/go) if I give it the project + creds, it should work locally as well as in GCP?


When it breaks this is the traceback:

Traceback (most recent call last):
File "/Users/daudn/Documents/clean_space/tgs_workflow/utils/logger.py", line 27, in <module>
class GoogleLogger(CloudLoggingHandler):

Google在此更改中添加了`client_info`参数：https://github.com/googleapis/google-cloud-python/pull/7849/files#diff-340196d499e9d0eea25cd457f53bfa42L31

我怀疑您在GCP环境中运行的是Google Cloud Python SDK的更新版本，在本地环境中运行的是较旧的版本。

Google added the `client_info` parameter in this change: https://github.com/googleapis/google-cloud-python/pull/7849/files#diff-340196d499e9d0eea25cd457f53bfa42L31

I suspect you are running a newer version of the Google Cloud Python SDK in your GCP environment and and older version on your local environment.
