MacOS X 安装Mercurial

Mercurial

以下是来自Mercurial官网的介绍

Mercurial is a free, distributed source control management tool. It efficiently handles projects of any size and offers an easy and intuitive interface.

Mercurial和当前广泛应用的git和svn都是源码版本管理工具。

Mercurial 是python编写的，安装前需要先安装好 python

• 检查python是否安装 python --version，以下是我使用的版本

Python 2.7.10

Mercurial 官网下载得到 mercurial-4.5 软件包

• 解压到合适的目录
• 进入主目录 cd mercurial-4.5
• make install 进行安装

安装过程中可能出现 docutils 模块缺失

abort: couldn’t generate documentation: docutils module is missing

从 http://docutils.sourceforge.net/ 下载docutils

docutils的安装
* tar -zxf docutils-0.14.tar.gz
* cd docutils-0.14
* sudo python setup.py install

重新 make install 安装Mercurial
