## 智能合约
#### 前置条件
若还没有安装truffle和ganache-cli的需要提前安装
```bash
npm install -g truffle@6.14.13
npm install -g ganache-cli@6.14.13
```
> node版本说明
> node@16.14.0
```
nvm use 16.14.0
```
若安装后，ganache-cli没生效，需要刷新下bash_profile
```
source ~/.bash_profile
```
若安装后，ganache-cli启动后，无法连接到truffle，需要修改truffle-config.js
```
networks: {
development: {
host: "127.0.0.1", // Localhost (default: none)
port: 8545, // Standard Ethereum port (default: none)
network_id: "*", // Any network (default: none)
},
}
```
#### 编译
```
truffle compile
```
#### 启动
新建一个窗口，启动服务
```
ganache-cli
```
#### 部署
```
truffle migrate
```
### 安装
```
yarn
```
### 运行
```js
// 启动前端
yarn serve
```
## 服务端
#### 前置条件
安装mysql
```bash
brew install mysql
```
另一种通过下载安装包进行安装，地址：https://downloads.mysql.com/archives/community/
选择自己的电脑对应的安装包，以及兼容的版本
安装完成后，启动，创建数据库
```bash
// 终端
mysql -u root -p
```
```bash
// 创建数据库
CREATE DATABASE database_name;
```
```bash
// 查看所有数据库
SHOW DATABASES;
```
### 安装
```
yarn
```
#### 运行
```js
// 启动服务
node index.js
```
## 常见问题
#### 1.程序中调用deployed()部署合约，报错Error: CrowdfundingCamp has not been deployed to detected network (network/artifact mismatch)
