Question

我需要做buildout谷歌应用引擎。我写了配置文件buildout.cfg：

[buildout]
parts =
    gae_sdk
    gae_tools
    app_lib

unzip = true
relative-paths = true
download-cache = etc/downloads
develop-eggs-directory = etc/develop-eggs
parts-directory = etc/parts


[gae_sdk]
recipe = appfy.recipe.gae:sdk
url = http://googleappengine.googlecode.com/files/google_appengine_1.4.3.zip
destination = ${buildout:parts-directory}
hash-name = false
clear-destination = true


[gae_tools]
recipe = appfy.recipe.gae:tools
sdk-directory = ${gae_sdk:destination}/google_appengine

[app_lib]
recipe = appfy.recipe.gae:app_lib
lib-directory = src/distlib
use-zipimport = false


eggs =
    webapp2

运行命令python＆lt;（curl http://python-distribute.org/bootstrap.py）--distribute和./bin/buildout GAE不想工作。服务器正在运行，但GAE站点中最简单的Hello世界显示错误importError：没有名为webapp2的模块。首先，我需要在我的脚本之后运行Hello world。文件和文件夹结构是：progect / buildout.cfg progect / src / hello_world.py,app.yaml

file app.yaml:
application: hello_world
version: 1
runtime: python
api_version: 1
threadsafe: true

handlers:
- url: /.*
script:hello_world.app

builtins:
- deferred: on

file hello_world.py:
import webapp2

class MainPage(webapp2.RequestHandler):
def get(self):
self.response.headers = ‘text/plain’
self.response.out.write('Hello, webapp World!')

app = webapp2.WSGIApplication(,
debug=True)
help me, please.

webapp2包含在最近的SDK中（google_appengine / lib / webapp2）。如果您使用较新的SDK或不导入webapp2，它应该适合您。

如果您对稍微不同的构建设置感兴趣，我已经包含了一个。

我一直在使用rod.recipe.appengine进行扩建，并对它非常满意。如果您需要修复PyCrypto imports等，它甚至允许您修补应用引擎SDK。

我根据bobo example和其他一些来源制作了我的配置。下面的示例允许您从dist.plone.org获取PIL之类的依赖关系，它为表单处理提取wtforms，为加密方便提取gdata，并将它们放在packages.zip中，可以在导入之前添加到sys.path，例如{ {1}} zippedpackages.py看起来像

import zippedpackages

另请注意，settings.py和app.yaml是通过模板生成的，并且插入了import sys if 'packages.zip' not in sys.path: sys.path.insert(0, 'packages.zip')和appspotname等变量。

buildout基于正在运行的buildout，但是这个确切的示例尚未经过测试，并且还缺少一些模板。如果你在pypi上查找不同的食谱，你可以阅读选项和语法。

如果使用模板，则可能必须运行buildout两次才能首先从模板生成文件（在我的设置中的src目录中），然后创建符号链接到parts目录（SDK运行的位置）。如果您不想要模板，请从buildout中删除并像平常一样进行设置。使用egg而不是virtualenv使您可以将库切换为配置而不是具有不同的virtualenv。但不是一个大问题，因为库版本很少改变。如果你遇到鸡蛋的问题，还值得注意的是SDK导入魔法知道站点包，在某种程度上知道virtualenvs，但不是蛋，所以有些库可能必须安装在virtualenv中。

appspotversion

app.yaml模板看起来像

[buildout]
appspotname = progect
appspotversion = dev

versions = versions
develop =
    src/progect
parts =
    progect
    progectconfig
    progectsettings
    nosetests
    noseconfig
    zipsymlink

unzip = true

find-links =
    http://dist.plone.org/thirdparty/

[progect]
recipe = rod.recipe.appengine
url = http://googleappengine.googlecode.com/files/google_appengine_1.6.6.zip
server-script = dev_appserver
packages =
    wtforms
    gdata
src = ${buildout:directory}/src/progect
exclude = tests
zip-packages = True
use_setuptools_pkg_resources = True
# We have a patch overriding imports to enable buildout and eggs
#patch = ${buildout:directory}/google_appserver.patch

[progectconfig]
recipe = collective.recipe.template
input = ${buildout:directory}/templates/app.yaml.in
output = ${progect:src}/app.yaml

[progectsettings]
recipe = collective.recipe.template
input = ${buildout:directory}/templates/settings.py.in
output = ${progect:src}/settings.py

[nosetests]
recipe = zc.recipe.egg
eggs =
    NoseGAE
    WebTest
    progect
    nose

extra-paths =
    ${buildout:directory}/etc
    ${buildout:directory}/parts/google_appengine
    ${buildout:directory}/parts/google_appengine/lib/antlr3
    ${buildout:directory}/parts/google_appengine/lib/django_1_3
    ${buildout:directory}/parts/google_appengine/lib/fancy_urllib
    ${buildout:directory}/parts/google_appengine/lib/ipaddr
    ${buildout:directory}/parts/google_appengine/lib/webob_1_1_1
    ${buildout:directory}/parts/google_appengine/lib/webapp2/
    ${buildout:directory}/parts/google_appengine/lib/yaml/lib
    ${buildout:directory}/parts/google_appengine/lib/simplejson
    ${buildout:directory}/parts/google_appengine/lib/graphy
interpreter = python

[noseconfig]
recipe = collective.recipe.template
input = ${buildout:directory}/templates/setup.cfg.in
output = ${buildout:directory}/setup.cfg

[zipsymlink]
recipe = svetlyak40wt.recipe.symlinks
path = ${progect:src}
files = ${progect:app-directory}/packages.zip

[versions]
Django = 1.3
gdata = 2.0.16
lxml = 2.3
PIL = 1.1.7
PyCrypto = 2.3
setuptools = 0.6c11
webapp2 = 2.3
WebOb = 1.1.1
WTForms = 1.0.1

# Tools and dependencies
svetlyak40wt.recipe.symlinks = 0.2.1

Nose测试配置模板，针对src目录运行测试（而不是主要的替代部件/ progect）：

application: ${buildout:appspotname}
version: ${buildout:appspotversion}
runtime: python27
threadsafe: true
api_version: 1

libraries:
- name: PIL
  version: "${versions:PIL}"
- name: pycrypto
  version: "${versions:PyCrypto}"
- name: django
  version: "${versions:Django}"
- name: lxml
  version: "${versions:lxml}"
- name: setuptools
  version: "${versions:setuptools}"
- name: webapp2
  version: "${versions:webapp2}"
- name: webob
  version: "${versions:WebOb}"

handlers:
- url: /.*
  script:hello_world.app
- url: /_ah/queue/deferred
  script: google.appengine.ext.deferred.application
  login: admin

builtins:
- deferred: on

当我想设置它时，我转到buildout根目录并输入

[nosetests]
verbosity=1
detailed-errors=1
with-gae=1
gae-application=${progect:src}
gae-lib-root=${buildout:directory}/parts/google_appengine
where=${progect:src}

然后我可以投放/path/to/appropriate/python bootstrap.py --distribute bin/buildout -c buildout.cfg或bin/nosetests

Answer 2

webapp2未包含在sdk中，如果您在buildout中使用沙箱或virtualenv，则需要将软件包安装到python环境中或将其包含在buildout中。
