由于粘贴，Pyramid mongodb 脚手架在 Python 3 上失败 [英] Pyramid mongodb scaffold failing on Python 3 due to Paste

问题描述

环境:

• Python 3.2.3(使用 virtualenv)
• 金字塔 1.4
• pyramid_mongodb 脚手架

使用 pyramid_mongodb 脚手架安装 myproject 后，我​​运行 python setup.py test -q 并且失败并出现以下错误.

After installing myproject using pyramid_mongodb scaffold I ran python setup.py test -q and it's failing with below errors.

running build_ext

        except HTTPException, exc:

我理解错误，Paste 与 python3 不兼容.我也知道如何修复它，但这基本上意味着将 Paste 移植到 python3(这是我不想做的事情)，所以有人能告诉我我能做什么吗?

I understand the error, that Paste is not python3 compatible. I also know how to fix it but that would essentially mean porting Paste to python3 (which is something I don't want to do), so can anyone tell what I can do?

从错误堆栈中，我看到 webob/exc.py 正在执行 from paste import httpexceptions 但是当我检查代码时，我看到导入位于 try except 块(在 except 中没有引发任何错误)，所以我什至在从lib 但是当我运行测试时，我看到 setup.py 再次安装 paste

From the error stack I see that webob/exc.py is doing from paste import httpexceptions but when I checked the code I see that the import is under a try except block (without raising any error in except), so I even tried the test after removing paste from the lib but then when I run the test, I see that the setup.py is installing paste again

running test
Checking .pth file support in .
/root/App/Big3/bin/python -E -c pass
Searching for Paste>=1.7.1

我检查了 .pth 文件并删除了对 paste 的引用，然后开始重新安装项目，但不知何故它仍然看到 paste 需要

I checked .pth files and removed reference to paste and then started re-installation of project but somehow it still sees paste as required

Installed /root/App/Big3/Myproject
Processing dependencies for Myproject==0.0
Searching for Paste>=1.7.1
Reading http://pypi.python.org/simple/Paste/

我的 setup.py 文件与 this 相同谁能告诉我这个 paste 依赖项在哪里进入我的项目.

My setup.py file is same as this Can someone tell me where is this paste dependency coming into my project.

推荐答案

我不打算回答我自己的问题，但由于我做出了对我有用的更改，我想我会在这里分享(假设有会是其他人想要在 python3 上使用 pyramid_mongodb 脚手架)

I didn't intend to answer my own question but since I have made changes which are working for me, I thought I will share it here (assuming that there would be other folks wanting to have pyramid_mongodb scaffold work on python3)

发展变化.ini

已删除

[pipeline:main]
pipeline =
    egg:WebError#evalerror
    {{project}}

改变了

[app:{{project}}] to [app:main]

已添加(可选)

pyramid.includes =
    pyramid_debugtoolbar

更换服务器(从粘贴到服务员)

Changed server (from paste to waitress)

[server:main]
use = egg:waitress#main
host = 0.0.0.0
port = 6543

Setup.py 中的更改更改需要从

requires = ['pyramid', 'WebError', 'pymongo']

到

requires = ['pyramid', 'pyramid_debugtoolbar', 'pymongo', 'uwsgi', 'waitress']

移除 webError 很重要

It's important to remove webError
