Termux中pip安装Telethon/Pyrogram失败，请求解决方案

在Termux环境下使用pip安装Telethon或Pyrogram时，出现**权限拒绝（Errno 13）**错误，导致无法生成包元数据。具体报错信息如下：

  note: This error originates from a subprocess, and is likely not a problem with pip.

已尝试以下命令但无效：

pkg install python-pip
pip install pyrogram
pip3 install pyrogram
MATHLIB="m" pip install pyrogram

解决方案 #

1. 清理pip缓存与临时文件残留 #

权限错误大概率是pip临时目录的缓存文件损坏或权限异常导致，先清理：

# 清理pip缓存
pip cache purge
# 删除Termux临时目录下的pip残留文件
rm -rf /data/data/com.termux/files/usr/tmp/pip-*

2. 使用用户级权限安装（推荐） #

Termux中不建议全局安装Python包，使用--user参数将包安装到用户专属目录，避免权限问题：

# 安装Telethon
pip install --user telethon
# 安装Pyrogram
pip install --user pyrogram

3. 更新Termux系统与依赖 #

确保Termux系统及所有组件为最新版本，避免兼容性问题：

pkg update && pkg upgrade -y
# 重新安装python-pip确保完整性
pkg reinstall python-pip -y

4. 手动安装依赖包 #

如果仍因pyaes依赖报错，先单独安装pyaes再装目标包：

pip install --user pyaes
# 再安装Telethon/Pyrogram
pip install --user telethon
