为什么引入xlswriter扩展后会报错。

Dockerfile多阶构建后的镜像

php -v
PHP Warning: PHP Startup: Unable to load dynamic library 'xlswriter.so' (tried: /usr/lib/php7/modules/xlswriter.so (Error relocating /usr/lib/php7/modules/xlswriter.so: add_next_index_zval: symbol not found), /usr/lib/php7/modules/xlswriter.so.so (Error loading shared library /usr/lib/php7/modules/xlswriter.so.so: No such file or directory)) in Unknown on line 0

单纯的看这一点报错信息，没办法得出最终结论，但是可以按照下面的步骤排查一下：

1. 多阶段构建是不是php版本不一样，然后你就直接复制过来用了
2. 复制的文件是否正确
3. docker打包的步奏参考一下官方的文档：https://xlswriter-docs.viest.me/zh-cn/an-zhuang/docker
