-> yum install sqlite sqlite-devel

pyenv 환경 다시 재설치
# CFLAGS="-I$(xcrun --show-sdk-path)/usr/include" pyenv install 3.9.4

 

 

sqlite3 버전확인.

      

      

      

    
    

      <bash />
    
# python3
Python 3.9.4 (default, Jul 10 2022, 14:34:24)

2. 2. django.core.exceptions.ImproperlyConfigured: SQLite 3.9.0 or later is required (found 3.7.17).

-> 최신버전 sqlite 설치

 

      

      

      

    
    

      <bash />
    
wget https://sqlite.org/2022/sqlite-autoconf-3390000.tar.gz
tar xvfz sqlite-autoconf-3390000.tar.gz
cd sqlite-autoconf-3390000
./configure --prefix=/usr/local/
make && make install
cp -arp /usr/local/bin/sqlite3 /usr/bin/sqlite3

sqlite3 --version
3.39.0 2022-06-25 14:57:57 14e166f40dbfa6e055543f8301525f2ca2e96a02a57269818b9e69e162e98918

그러나 PYTHON 버전에서 sqlite로 했을 때에는 기존 버전을 바라보고 있다.

 

      

      

      

    
    

      <bash />

      <bash />
    
라이브러리 위치를 최신버전을 설치한 sqlite3쪽으로 향하게 해준다.
# echo $LD_LIBRARY_PATH

# export LD_LIBRARY_PATH="/usr/local/lib"
# echo $LD_LIBRARY_PATH
/usr/local/lib


영구적으로 라이브러리 위치를 지정하고 싶다면
# vi /etc/ld.so.conf.d/sqlite.conf
/usr/local/lib
