当我尝试运行 pyramid 时

[~/env/MyStore]# ../bin/pserve development.ini

它会显示以下错误

File "/home/vretinfo/env/lib/python3.2/site-packages/Paste-1.7.5.1-py3.2.egg/paste/fileapp.py", line 14, in <module>
    from paste.httpheaders import *
File "/home/vretinfo/env/lib/python3.2/site-packages/Paste-1.7.5.1-py3.2.egg/paste/httpheaders.py", line 140, in <module>
    from rfc822 import formatdate, parsedate_tz, mktime_tz
ImportError: No module named rfc822

我该如何解决这个问题呢?


这是我安装时所做的步骤

$ mkdir opt
$ cd opt
$ wget http://python.org/ftp/python/3.2.3/Python-3.2.3.tgz 
$ tar -xzf Python-3.2.3.tgz
$ cd Python-3.2.3

./configure --prefix=$HOME/opt/Python-3.2.3

$ make; 
$ make install
$ cd ~
$ wget http://python-distribute.org/distribute_setup.py
$ pico distribute_setup.py
* change first line to opt/Python-3.2.3/python
$ opt/Python-3.2.3/bin/python3.2 distribute_setup.py
$ opt/Python-3.2.3/bin/easy_install virtualenv
$ opt/Python-3.2.3/bin/virtualenv --no-site-packages env
$ cd env
$ ./bin/pip install passlib
$ ./bin/pip install pyramid_beaker
$ ./bin/pip install pyramid_mailer
$ ./bin/pip install pyramid_mongodb
$ ./bin/pip install pyramid_jinja2
$ ./bin/pip install Werkzeug
$ ./bin/pip install pyramid 
$ ./bin/pcreate -s pyramid_mongodb MyShop
$ cd MyShop
$ ../bin/python setup.py develop
$ ../bin/python setup.py test -q

好的,我在 pyramid 的文档上查了一下( http://docs.pylonsproject.org/projects/pyramid/en/latest/narr/paste.html )。 在第三段中它提到:

“然而,所有 Pyramid 的脚手架都会生成 PasteDeploy 配置文件,以便为新开发者提供一种标准化的设置部署值的方法,并为新用户提供一种标准化的启动、停止和调试应用程序的方法。”

所以我对 development.ini 文件进行了修改,并替换了

[server:main]
use = egg:waitress#main

在 setup.py 中,我把 'waitress' 加入了需要的数组里

接下来的步骤,我完全删除了与 Paste 相关的所有内容,在 /home/vretinfo/env/ECommerce/ 目录下,

$ rm -rf Paste*;rm -rf paste*

之后,我再次尝试运行 test -q,这时得到了这个堆栈跟踪:

[~/env/ECommerce]# ../bin/python setup.py test -q

/home/vretinfo/opt/Python-3.2.3/lib/python3.2/distutils/dist.py:257: UserWarning: Unknown distribution option: 'paster_plugins'

看起来 pyramid1.4 似乎需要 paste,可能有人对此有一些见解。

我通过IRC#pyramid的朋友们解决了这个问题。为了方便将来遇到相同问题的人,我把解决方案发在这里。我在Python3.2上测试过,现在可以正常工作了。

在项目文件夹中运行 ./bin/pcreate -s <...>

然后找到development.ini文件。

接下来,修改以下内容:

    1. in the 1st line, rename [app:<Project>] to [app:main]

    2. [server:main]
       If it is egg:Paste#http, change it to

       use = egg:waitress#main

    3. remove [pipeline:main] and its section

在同一个文件夹中,修改setup.py文件:

    1. requires = [....], add in waitress into the array, remove WebError from the array
    2. remove paster_plugins=['pyramid']

最后,运行

    $ ../bin/python setup.py develop

这样就不会安装Paste,也不会检查它是否存在。
