一下引用，只是技术记录交流
目前来讲，学习任何EOS相关技术的资料都来自https://github.com/EOSIO/eos，大家可能在搭建EOS开发环境的过程中，会很迷茫，网上资料都很乱，自己也理不清头绪，不知如何下手。在这里，春哥将一步步为你揭开层层面纱。
1.硬件软件环境
因为EOS的版本太多，你所以先需要知道如何查看EOS对应版本的相关资料。
打开EOS Github官网https://github.com/EOSIO/eos，如下图所示，点击master，然后点击tag，你将会看到不同的版本及其对应的文档。
我在我电脑安装过各种各样的版本，踩过各种各样的莫名其妙的坑，这篇文章我将以如下配置为大家分享。
-
操作系统
-
EOS版本
2.编译设置开发环境
2.1获取EOS源码及其所有子模块
$ git clone https://github.com/eosio/eos --recursive如果代码克隆未时带--recursive参数，那么可切换到项目路径下面执行如下命令，更新子模块。
$ git submodule update --init --recursive2.2编译源码生成可执行文件
切换到上面的项目根目录下面，执行如下命令。

To verify your installation run the following commands:
/usr/local/bin/mongod -f /usr/local/etc/mongod.conf &
cd /Users/liyuechun/eos/build; make test

eosio-launcher：节点网络组成和部署的应用
这些所有程序/eos/build/programs都存在于这个文件夹数。
2.3建立区块链节点
到e月刊目录eos/build/programs/nodeos下面，然后执行如下命令。
./nodeos柯林斯命令附带 --data-dir 节点文件夹名字 参数，默认文件夹为nodeos。
liyuechun:nodeos yuechunli$ ./nodeos
如下图所示，完执行./nodeos程序后会抱错，并且有如下两个提示。

blocks default.wallet shared_memliyuechun:data yuechunli$ config是区块链配置文件，data是区块链交易数据，钱包数据存储文件。需要我们修改config.ini文件里面的相关配置。

plugin = eosio::chain_api_plugin -
plugin = eosio::http_plugin
再次接下来启动./nodeos程序，每0.5秒会产生一个区块。
