官方回复

@Reverier-Xu @stephen-a2z @dumindu @pwittchen
 
We published v4.2.1.
v4.2.1 has included fixed compatible with Node 14.
 
Thanks :)

但是更新到 4.2.1 之后问题依旧。

另觅方法

降级 Node.js?

sudo pacman -U /var/cache/pacman/pkg/nodejs-13.13.0-1-x86_64.pkg.tar.zst

用 pacman 的缓存降到了 13.13 版本，这个方法工作了大概一个星期。

紧接着，Node.js 的依赖库更新了…

于是全部木大

如果我想继续使用降级 Node.js, 那我就必须把依赖库都降级，同时还要降级其它的所有依赖的与被依赖的软件包，直到官方兼容 Node 14.2.

可是，我这是 Arch Linux 啊，降级？大规模降级？恐怕等官方修复了之后我再更新，就滚挂了吧。

虚拟机？

尝试在 Linux 里面开 Linux 虚拟机竟然只是为了更新博客？我感觉我脑子还没坏 emm

docker? docker 是对的

那不如用 docker 吧。

安装好 docker 之后获取官方的 docker 镜像：

sudo docker pull node:13.14.0-stretch

用以下命令启动 docker 环境，并挂载博客目录，将 hexo 的服务器端口 4000 映射到本机的 4000:

sudo docker run -it -p 4000:4000 -v <Blog Location>:/Blog node:13.14.0-stretch /bin/bash

装好依赖，配置好 git 的 SSH Key, 然后使用 sudo docker ps -l 查询容器 pid, 接着：

sudo docker commit <pid> node:13.14.0-stretch

保存配置好的环境。

编写一个简单的 .desktop 文件：

[Desktop Entry]
Comment=
Exec=konsole -e 'sudo docker run -it -p 4000:4000 -v /home/reverier/文档/Blog:/Blog node:13.14.0-stretch /bin/bash'
GenericName=Docker Blog
Icon=
Name=Blog
NoDisplay=false
Path[$e]=
StartupNotify=true
Terminal=0
TerminalOptions=
Type=Application
X-KDE-SubstituteUID=false
X-KDE-Username=

扔到 ~/.local/share/applications 目录下面。

写博客还和以前一样，写好之后点一下这个桌面文件，输入 root 密码，然后和以前一样更新博客就可以了。

结尾

学了一点简单的 docker 用法，感觉还不错呢~
