之前我们演示了scatter 扩展版本,添加测试网络的演示 （《Scatter的使用及添加测试网络相关设置》）
目前scatter官方已经明确废弃了扩展版本，主推桌面版本ScatterDesktop

1.下载ScatterDesktop

请到https://github.com/GetScatter/ScatterDesktop/releases 下载最新版本

2.安装

我们将在mac系统演示，下载下来后，直接运行安装包，将scatter拖到Applications

3.创建scatter

输入密码点击，点击Create new Scatter。如果之前有备份，可以点击Import from Backup

3.1点击Accept

3.2选择一个目录，作为备份的保存位置

3.3进入主界面

3.4进入设置

3.5进入网络设置

3.6输入scatter密码（新建scatter时设置的密码）

3.7新建网络

3.8输入麒麟网某节点的配置

host: api.kylin.eosbeijing.one
port: 8880
chainId: 5fff1dae8dc8e2fc4d5b23b2c7665c97f9e9d8edf2b6485a86ba311c25639191

点击保存。

4添加账号

如果没有麒麟网的账号的话，可以先去注册下，并申请测试代币
访问： https://tools.cryptokylin.io/#/tools/create

4.1进入Vault

4.2点击新建New

4.3点击导入

4.4导入麒麟网账号的私钥

4.5粘贴私钥后，进入账号检测，稍等片刻，即可显示，并自动导入，当前私钥下的所有账号。

至此ScatterDesktop的下载，安装，添加测试网络，以及账号，已经演示完毕。

其他帮助

清除ScatterDesktop本地数据

终端运行

find ~ -iname  "scatter*"

查找本地scatter目录，一般是在/Users/你的当前机器登陆的账户/Library/Application\ Support/scatter/
清空目录

rm -rf /Users/你的当前机器登陆的账户/Library/Application\ Support/scatter/

Mac系统编译

首先确认下当前机器安装的node的版本为v9.8.0，否则无法编译通过。切换版本，可参考《mac os 安装指定版本 node》

开始编译

进入源代码目录，安装依赖

yarn install

编译源码

npm run build

生成对应平台安装包
mac:

npm run release-mac

windows:

npm run release-windows

linux:

npm run release-linux

编译成功

• 编译完，运行，界面空白
  经过反编译app.asar，发现缺少dist
  解决方案：先运行npm run build，在运行npm run release-win

其他

• 反编译asar

  npm install -g asar
  asar extract app.asar ./

由于编译ScatterDesktop时，使用brew install node安装的node为最新版本v11+，由于对应的源代码没有做兼容，导致编译出错。所以才有此文，需要安装对应需要的版本。

node版本管理工具nvm

安装nvm

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.30.2/install.sh | bash

此时会生成 ~/.bash_profile，添加nvm 到环境变量。
刷新环境变量，使其生效

source ~/.bash_profile

此时打开终端，输入nvm会输出，对应的帮助信息。

使用nvm安装node

所需命令如下

$ nvm ls-remote 查看 所有的node可用版本
$ nvm install xxx 下载你想要的版本
$ nvm use xxx 使用指定版本的node 
$ nvm alias default xxx 每次启动终端都使用该版本的node 

由于我们目前需要的是 node v9.8.0
所以执行命令如下

$ nvm install v9.8.0
$ nvm use v9.8.0
$ nvm alias default v9.8.0

查看node版本 v9.8.0

node -v
