Say before

This document mainly help developers install most requirements for VNTChain、gvnt、bottle、vnt.js、vnt-kit.js.
I have cost a lot to do this even if I followed the official guide.Maybe there is a long time since doc updated last time.

Install tools

1. Node.js v8.11.2

Common way

1. Download from Node.js Mirror

2. Unzip (e.g tar -xf xxx.tar.gz)

3. Add bin folder to your environment

2. go-vnt(gvnt)

Go (v1.9+) and C compile required.

Same way to README.md in Github

1. Download

   git clone https://github.com/vntchain/go-vnt.git

2. Switch tree

   git checkout v0.6.4-alpha.6

3. compille

   make gvnt

   If failed , please install go v1.10 and retry.

4. link to your environment

3. bottle

docker required

1. Download from official docker hub

   sudo docker pull vntchain/bottle:0.6.1

   If fail,check status of docker service

2. Check image exists

   sudo docker image ls

   maybe show like this

   REPOSITORY        TAG       IMAGE ID       CREATED       SIZE  
   vntchain/bottle   0.6.1     647ad4101419   2 years ago   1.9GB

4. vnt.js && vnt-kit.js

git、gcc 、Node.js v8.11.2 required

These javascript packages are used to delopy and smart contract.

This is the only SDK with VNTChain.We can use Nodej.js as back-end language.

1. Init project

   npm init

2. Download

   npm install --save https://github.com/vntchain/vnt.js.git
   npm install --save https://github.com/vntchain/vnt-kit.js.git

   If fail ,please use --python=python2.(Python2 required) like this

   npm install --save https://github.com/vntchain/vnt.js.git --python=python2
   npm install --save https://github.com/vntchain/vnt-kit.js.git --python=python2

3. Download other requirements

   npm install --save ethereumjs-tx@1.3.7
   npm install --save ethereumjs-account

Some Experience

1. "Error: Python executable "/usr/bin/python" is v3.9.7, which is not supported by gyp." when npm install in project

Python2 required. You have to run command like this npm install --python=python2 after installing python.

2. "no required module provides package github.com/vntchain/go-vnt/internal/build: go.mod file not found" when make gvnt

This is because go version is too high. You have to install go in lower version like v1.10, and then retry.
