青云平台搭建truffle

1安装node
直接在nodejs官网下载nodejs-v6.10.x编译好的压缩包（tar.gz)， 里面自带了npm（推荐此方法）。

下载成功后，cd 到nodejs下载的目录，直接把nodejs解压到/usr/local中。

wget https://nodejs.org/dist/v8.1.2/node-v8.1.2-linux-x64.tar.xz
root@i-5tthrr8u:/home/ubuntu#tar -xvf node-v8.1.2-linux-x64.tar.xz -C /usr/local/

查看/usr/local目录如下：
root@i-5tthrr8u:/home/ubuntu# ls /usr/local
bin  etc  games  include  lib  man  node-v8.1.2-linux-x64  sbin  share  src
root@i-5tthrr8u:/home/ubuntu# vim ~/.profile

设置PATH环境变量,编辑~/.profile,并在末尾添加node文件夹路径到$PATH环境变量中。


# ~/.profile: executed by Bourne-compatible login shells.

if [ "$BASH" ]; then
  if [ -f ~/.bashrc ]; then
    . ~/.bashrc
  fi
fi

mesg n || true
PATH="$HOME/bin:$HOME/.local/bin:/usr/local/node-v8.1.2-linux-x64/bin:$PATH"

检查nodejs,注销或者重启电脑（.profile)中设置的$PATH需要重启，或者在终端中运行： source ~/.profile

root@i-5tthrr8u:/home/ubuntu#  source ~/.profile
root@i-5tthrr8u:/home/ubuntu# node --version
v8.1.2
root@i-5tthrr8u:/home/ubuntu# npm --version
5.0.3

2：安装truffle 和 testrpc

root@i-5tthrr8u:/home/ubuntu# sudo npm install -g truffle
bash: sudo: command not found
root@i-5tthrr8u:/home/ubuntu# npm install -g truffle
/usr/local/node-v8.1.2-linux-x64/bin/truffle -> /usr/local/node-v8.1.2-linux-x64/lib/node_modules/truffle/build/cli.bundled.js
+ truffle@3.3.2
added 90 packages in 80.11s
