## 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 [email protected]

npm install -g [email protected]

```

> node版本说明

> [email protected]

```

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)
