解决树莓派找不到sqlite3 的问题

• 问题描述

WARNING: The Python bz2 extension was not compiled. Missing the bzip2 lib?

WARNING: The Python readline extension was not compiled. Missing the GNU readline lib?

WARNING: The Python sqlite3 extension was not compiled. Missing the SQLite3 lib?

树莓派已经安装了sqlite3 ，但是用pyenv 安装完3.8.3 的python提示没有安装sqlite3 扩展，后续使用也会报模块找不到

尝试重装python 3.8.3 版本依然无法找到sqlite3

• 下载sqlite

  https://www.sqlite.org/2020/sqlite-autoconf-3320300.tar.gz
  tar zxf sqlite-autoconf-3320300.tar.gz
  cd sqlite-autoconf-3320300
  ./configure --prefix=/usr/local
  make
  make install
  

• 重装python 3.8.3

  pyenv uninstall 3.8.3
  pyenv install 3.8.3
  

• 最终排查是树莓派pyenv的环境问题

一定要安装软件依赖

sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm
