Question

我试图安装一个devstack edx，但我遇到了一些问题。我找到了这篇文章

How to fix python requirements update error (master branch) - SSO feature merged

但是没有为我工作。当我尝试启动服务器时，我得到了下一个失败：

顺便说一句，我已经尝试更新pip，看起来一切正常（已成功安装pip-7.1.0），但在尝试paver devstack studio时我总是收到该消息。

Answer 1

如果上述步骤不起作用，请尝试从Vagrant实例安装Cython，meliae == 0.4.0和libxmlsec1。

Answer 2

通过以下步骤解决此问题：

Requested meliae==0.4.0 (from -r requirements/edx/base.txt (line 53)),but installing version None

此行定义当vagrant尝试安装所有base.txt文件依赖时，base.txt文件中存在错误。

分步解决这个问题：

1）打开base.txt文件并发表评论meliae==0.4.0行，如（#meliae==0.4.0）

2）现在尝试pip install -r base.txt文件，如果它成功运行然后没有问题，或者如果任何其他包创建问题，则按照1（现在评论）步骤。

3）成功运行base.txt 3.1）来自exit的{{1}} 3.2）关于vagrant实例（在edx-platform命令之后）安装所有注释包（在我的情况下为vagrant ssh）

现在再次运行你的lms系统：）
