aliyundrive-webdav安装失败

[eastonlian]

架构查询如下：

opkg print-architecture
arch all 1
arch noarch 1
arch ar71xx 10

查了openwrt wiki对应的是mips_24kc架构（路由器型号TL-WR941N），选了aliyundrive-webdav_1.3.1_mips_24kc.ipk安装仍提示

Unknown package 'aliyundrive-webdav'.
Collected errors:
 * pkg_hash_fetch_best_installation_candidate: Packages for aliyundrive-webdav found, but incompatible with the architectures configured
 * opkg_install_cmd: Cannot install package aliyundrive-webdav.

后面参考#44尝试在/etc/opkg.conf添加arch mips_24kc 100，安装期间则提示出错return 127.

OpenWRT 系统版本太老了吧？本项目只支持 19.07 及以后版本。
