我已经安装了适用于 Windows 的 Google Cloud SDK 并选中了该框以获取捆绑的 python 安装（版本 2.7.13）。 Python 安装检查

基本上按照下面链接中的说明让 Hello World 应用程序在本地环境中工作（直到“进行更改”步骤）。 https://cloud.google.com/appengine/docs/standard/python/quickstart

现在，当我将语句添加import subprocess到 main.py 文件时出现了问题。

请注意，确切的问题在于import _subprocess模块“subprocess.py”中的行。这对我来说很奇怪，因为如果我尝试运行任何基本的 python 脚本（不dev_appserver.py app.yaml用于部署谷歌云环境），或者如果我只是直接从控制台使用 python 解释器（Windows 命令提示符），我在尝试import subprocess也不会出错如果我尝试import _subprocess直接。 从控制台 Python 导入语句。

这是 Hello World 代码（添加了子流程导入）：

import webapp2
import subprocess

class MainPage(webapp2.RequestHandler):
    def get(self):
        self.response.headers['Content-Type'] = 'text/plain'
        self.response.write('Hello, World!')



app = webapp2.WSGIApplication([
    ('/', MainPage),
], debug=True)

最后，我的熟人之前安装了相同的软件，并且在运行任何使用此导入语句的应用程序时都没有出现此类错误。

注意：我正在使用 Windows 10 机器。

解决方案

[更新]

我无法在已安装的 Google Cloud SDK 版本中解决此问题。

但是，安装旧版本（特别是捆绑了 python 的版本 220.0.0）解决了该import subprocess错误。出于我的目的，这是可以接受的。

以下是我的工作安装的详细信息：

C:\Users\MicroSilicon>gcloud version
Google Cloud SDK 220.0.0
app-engine-python 1.9.77
app-engine-python-extras 1.9.74
bq 2.0.34
cloud-datastore-emulator 2.0.2
core 2018.10.08
gsutil 4.34
