我在Ubuntu 18.04上重新安装了sphinixsearch，因为我在mataticore搜索中遇到了一些麻烦。但是现在我不能运行索引:
# indexer --all
Command 'indexer' not found, but can be installed with:
apt install sphinxsearch
但是重新安装后，命令也不运行work
但是我可以看到服务正在运行:
# systemctl status sphinxsearch.service
● sphinxsearch.service - LSB: Fast standalone full-text SQL search engine

有趣的是，第一次安装sphinix(在删除它并安装manticoresearch之前)，我可以使用indexer命令和sphinix搜索。所以我想我已经删除了一些二进制文件apt --purge remove sphinixsearch或manticoresearch已经造成了一些损害。无论哪种情况，我都无能为力，谢谢你的提示。
好了，我通过删除sphinix然后重新安装来解决问题:
apt remove sphinxsearch
apt install sphinxsearch
