Python3(22)：Centos7使用PyInstaller打包出现OSError: Python library not found

PyInstaller打包python程序

$pyinstaller -F casb_data.py

查看错误：OSError: Python library not found: libpython3.8m.so, libpython3.8m.so.1.0, libpython3.8mu.so.1.0, libpython3.8.so.1.0

解决提示：

If you're building Python by yourself, please rebuild your Python with `--enable-shared` (or, `--enable-framework` on Darwin)

解决方法：

#进入下载的python安装包，解压缩目录,重新配置和编译执行

$cd /home/cg/Python-3.8.6

$./configure --prefix=/usr/local/python3 --enable-shared

出现上面情况：重新配置

$./configure --prefix=/usr/local/python3 --enable-framework

出现上面情况：重新配置

$./configure --prefix=/usr/local/python3 --enable-optimizations

这次终于配置完成了，再次编译和执行

$make && make install

 

再次执行打包程序

#进入python目录

$pyinstaller -F casb_data.py

提示：/usr/local/python3/bin/python3.8: error while loading shared libraries: libpython3.8.so.1.0: cannot open shared object file: No such file or directory

 

原因是因为python运行时没有加载到libpython3.8.so.1.0这个库文件，将其复制到响应目录

$cp /usr/local/python3/lib/libpython3.8.so.1.0 /usr/lib64/

 

重新执行打包程序-->执行OK，yet.

$pyinstaller -F casb_data.py
