Rekall法医框架：readline的建筑轮子失败

Question

在安装最新版本的Google Rekall法医框架时，在安装“ rekall-agent”的步骤中显示：“ readline的构建轮失败”

我正在Kali Linux（2016-02）上安装它，默认python版本是2.7.12
在安装rekall-agent的步骤中，我遇到异常和错误。这是带有详细开关的错误部分：

我还尝试从错误日志中重新安装“ gcc ”和“ python2.7-dev ”，并搜索其他主题，我当时认为问题是关于它们的，但未解决

Answer 1

真正的问题是这一行：

/usr/bin/ld: cannot find -lncurses

通常，这意味着链接器无法找到构建程序包所需的特定库存档。 检查您是否已安装ncurses ，或通过以下方式安装

$ apt install ncurses
