Question

当进入教程 Build an Android App Using Firebase and the App Engine Flexible Environment 时，我得到了一个我无法解决的Apache Maven 3.3.9 Exception。

在教程中必须运行

火力-的AppEngine-后端

示例，这就是我的问题的原因。

以下是Exception：

它说无法运行Pyton.exe，但我有

C：\ Users \ sven \ AppData \ Local \ Google \ Cloud SDK \ google-cloud-sdk

它安装正确，Pyton也在那里。另外，我以管理员身份运行CMD。

如何解决此问题并运行以下内容？

firebase-appengine-backend示例

我确实使用Google Cloud SDK Shell而不是Windows 10 CMD窗口解决了这个问题。

我将云SDK安装到：

C：\ GoogleCloudSDK \ Cloud SDK \ google-cloud-sdk

并像这样运行：

mvn gcloud：run -Dgcloud.gcloud_directory =“C：\ GoogleCloudSDK \ Cloud SDK \ google-cloud-sdk”

但这又出现了另一个错误：

python.exe：无法打开文件'C：\ GoogleCloudSDK \ Cloud SDK \ google-cloud-sdk / platform / google_appengine / dev_appserver.py'：[Errno 2]没有这样的文件或目录

平台文件夹下不存在 google_appengine 文件夹？

dev_appserver.py位于：

C:\GoogleCloudSDK\Cloud SDK\google-cloud-sdk\bin

gcloud info ：

Google Cloud SDK 124.0.0
bq 2.0.24
bq-win 2.0.24
bundled-python 2.7.10
core 2016.08.29
core-win 2016.08.05
gcloud
gsutil 4.21
gsutil-win 4.20
powershell 0.1.5
windows-ssh-tools 2016.05.13

为什么Maven无法运行此构建运行？
