appengine_config.py

Question

执行dev_appserver.py时，我收到以下错误：

from google.auth import app_engine
File "/google/google-cloud-sdk/platform/google_appengine/google/appengine/tools/devappserver2/    python/runtime/sandbox.py"
, line 1147, in load_module
    raise ImportError('No module named %s' % fullname)
ImportError: No module named google.auth

奇怪的是，当我部署应用程序时，它运行正常。

我试过了：

dev_appserver.py MY_DIRECTORY
cd / google / google-cloud-sdk / bin /; python dev_appserver.py MY_DIRECTORY
python dev_appserver.py hello_world /
已安装更新的gcloud组件安装app-engine-go

其他信息：

没有使用虚拟环境。
dev_appserver的路径：/ google/google-cloud-sdk/bin/dev_appserver.py
我正在使用Google的Console Cloudshell

我解决了这个问题：

dev_appserver.py没有使用我的lib文件夹中的模块。相反，它使用我的计算机上的包。为了解决这个问题，我从本地计算机中删除了所有Google软件包，现在它运行良好。

我通过以上评论解决了这个问题：

是的，我在appengine_config.py中有以下内容：

from google.appengine.ext import vendor

vendor.add('lib')

我设法通过使用以下代码来解决模块加载问题：

appengine_config.py

import os
import google
from google.appengine.ext import vendor

lib_directory = os.path.dirname(__file__) + '/lib'

# Change where to find the google package (point to the lib/ directory)
google.__path__ = [os.path.join(lib_directory, 'google')] + google.__path__

# Add any libraries install in the "lib" folder.
vendor.add(lib_directory)

Answer 2

我在from google.auth.crypt import base中很有可能遇到了问题，并且已经解决了，因此您可以尝试一下。

转到存在导入问题的文件，然后手动更改：

from google.auth import app_engine

到：

import app_engine

App Engine未在dev_appserver.py
