进入 vendor 中，确实没看到 TokenHelper 这个类。手动去官网复制一份下来。
https://github.com/bobthecow/psysh/blob/main/src/Readline/Interactive/Helper/TokenHelper.php

进入到 vendor 目录，创建 TokenHelper.php 文件，复制代码进去。

        }

        return \in_array($lastToken, self::TRAILING_CHAR_OPS, true);
    }
}

再重启 composer。

composer dump-autoload -o

再使用 tinker 就可以了。
