- Can only install one of: simplito/elliptic-php[1.0.4, 1.0.6].
- Can only install one of: simplito/elliptic-php[1.0.4, 1.0.6].
- nebulas/neb.php 0.0.2 requires simplito/elliptic-php 1.0.4 -> satisfiable by simplito/elliptic-php[1.0.4].
- Installation request for nebulas/neb.php ^0.0.2 -> satisfiable by nebulas/neb.php[0.0.2].
- Installation request for simplito/elliptic-php (locked at 1.0.6) -> satisfiable by simplito/elliptic-php[1.0.6].

我这边使用了有这个了，你这个是固定死了版本，能修改兼容吗？
"simplito/elliptic-php": "^1.0"
