WP-CLI 是管理 WordPress 的强大命令行工具，以下是各种操作系统下的安装方法：

## 一、Linux/macOS 安装方法

### 1. 使用 curl 下载（推荐）

```bash
curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar
```

### 2. 验证文件完整性

```bash
php wp-cli.phar --info
```

### 3. 使其可执行并移动到 PATH

```bash
chmod +x wp-cli.phar
sudo mv wp-cli.phar /usr/local/bin/wp
```

### 4. 验证安装

```bash
wp --info
```

## 二、命令重置管理员角色
```bash
wp role reset administrator
```

会提示：Restored 61 capabilities to and removed 0 capabilities from 'administrator' role.
Success: Role reset.

再重新登录即可正常进入。

## 其他方法
还有一种方法，直接通过 SQL 重置。
```
