如何在ubuntu上安装devstack kilo时解决此错误

Question

这就是我所做的：

1）使用以下命令克隆devstack kilo：

git clone https://github.com/openstack-dev/devstack.git -b stable / kilo

2）cd devstack

3）./ stack.sh

在ubuntu上安装devstack kilo时出现以下错误。

You are using pip version 7.1.2, however version 8.0.2 is available. You should consider upgrading via the 'pip install --upgrade pip' command.

以下是截图：

我认为错误是由python包引起的。我更新了python并再次尝试但无济于事。

错误是什么，我该如何解决？

Answer 1

在命令行中：

public enum MyEnum
{
    [Description("Option One")]
    Option_One
}

public static string ToDescriptionString(this Enum This)
{
    Type type = This.GetType();

    string name = Enum.GetName(type, This);

    MemberInfo member = type.GetMembers()
        .Where(w => w.Name == name)
        .FirstOrDefault();

    DescriptionAttribute attribute = member != null
        ? member.GetCustomAttributes(true)
            .Where(w => w.GetType() == typeof(DescriptionAttribute))
            .FirstOrDefault() as DescriptionAttribute
        : null;

    return attribute != null ? attribute.Description : name;
}

这对我来说很好......

Answer 2

这对我有用。

sudo apt-get install python-pip

sudo pip install --upgrade pip

看起来我已经安装并升级了python。

我记得以前尝过这个但是没有用。我不知道为什么，但它现在有效。

如果任何人都可以说明错误背后的原因并描述解决方案，那将会很有帮助。
