问题分析： pip install bleach 报错通常由网络问题、依赖冲突或环境配置导致。以下是常见解决方案：

1. 网络问题（最常见）

# 使用国内镜像源
pip install bleach -i https://pypi.tuna.tsinghua.edu.cn/simple

# 或使用阿里云镜像
pip install bleach -i https://mirrors.aliyun.com/pypi/simple/

2. 升级pip和setuptools

python -m pip install --upgrade pip setuptools wheel
pip install bleach

3. 清理缓存重试

pip cache purge
pip install bleach --no-cache-dir

4. 检查Python版本兼容性 Bleach 6.0+ 需要 Python ≥3.7，确认版本：

import sys
print(sys.version)

5. 完整环境解决方案

# 创建干净虚拟环境（推荐）
python -m venv clean_env
source clean_env/bin/activate  # Linux/Mac
# clean_env\Scripts\activate   # Windows

pip install --upgrade pip
pip install bleach -i https://pypi.tuna.tsinghua.edu.cn/simple

如果仍有问题，请提供具体错误信息（复制完整的红色报错文本），常见错误类型：

  • SSL Certificate Verify Failed → 添加 --trusted-host pypi.org --trusted-host files.pythonhosted.org
  • 权限错误 → 添加 --user 参数或使用管理员权限
  • 依赖冲突 → 先安装指定版本：pip install "bleach<6.0"（兼容旧环境）

一句话建议： 优先使用国内镜像源并确保网络通畅。

是不是 pip/setuptools 版本太低了，装最新版试试

pip install --upgrade pip
pip install --upgrade setuptools

更新一下先

除了版本问题，基本上遇到的 pip 安装报错都是依赖的 devel 找不到，这种错误拿关键字去 google 里搜应该都可以找到。。

问题已解决，解决方法是按照 的方法，升级了 pip 和 setuptools 之后再执行 pip install bleach 后安装成功，感谢

这是基本操作=。=
