为什么我尝试运行金字塔项目时会出现DistributionNotFound错误？

Question

我安装在新的Windows 8（x64）中：

• Python-2.7
• pywin32-218.win32-py2.7版本
• 设置工具-0.6c11.win32-py2.7
• 和金字塔（通过简易安装）

我试图运行我的金字塔项目：

pserve I:\Projects\PyramidProject\development.ini

和pkg_resources.DistributionNotFound（req）被引发：

你知道吗，我做错什么了？

Answer 1

您需要在virtualenv中运行easy_install paste和python setup.py develop。

另一方面，你使用的是一个非常古老的金字塔版本。我知道这一点是因为您的项目使用weberror、repoze.tm2和paste。如果你有时间，我建议你考虑升级到一些最佳实践。
