记录一下
由于windows下无法成功使用electron-builder打出linux包
https://blog.csdn.net/weixin_42050406/article/details/106722691
于是在linux下搞一搞
纯记录，按照运行和打包遇到的问题写的，有弯路
具体处理方式建议直接看后半段
首先是运行的时候
peError: Cannot read property 'on' of undefined

卸载依赖重装√
注：如果遇到权限问题 安装命令请执行sudo npm install
打包时遇到：

这个问题在windows打包也遇到过，就是网络问题
把需要的文件直接放到缓存里
electron淘宝镜像：https://npm.taobao.org/mirrors/electron/
appimage：
结果又遇到新报错

参考https://github.com/electron-userland/electron-builder/issues/4629
将builder版本降低到21.2.0（感觉没用）
按照报错提示运行
snap install snapcraft --classic
结果遇到
-bash: snap: command not found
安装snap
sudo apt-get install snapd
结果遇到
真是错错无穷也哈哈哈哈哈哈
网上说是软件源未更新造成的，于是执行：sudo apt-get update 来更新软件源
等它更新完，再执行安装命令sudo snap install snapcraft --classic
继续报错- Download snap “core” (9668) from channel “stable” (read tcp 10.30.61.186:50756->91.189.88.179:443: read: connection reset by peer)
应该是网络问题，重试几下就好
上面这个命令又报错
error: cannot perform the following tasks:
- Mount snap "core" (9668) ([start snap-core-9668.mount] failed with exit status 1: Job for snap-core-9668.mount failed.
See "systemctl status snap-core-9668.mount" and "journalctl -xe" for details.
)
一路报错，太心累了
根据提示 查看详细内容journalctl -xe
看样子是没有xz这个压缩解压工具？？
使用命令apt-get install xz-utils
结果还是报之前的错，根据提示，使用命令systemctl status snap-core-9668.mount查看详情
放两个参考链接
https://github.com/lxc/lxd/issues/3421
一样的错误，但别人update源之后就能成功安装，然而我不行，我还用了sudo apt-get upgrade
apt-get update 是更新本地软件列表，在线安装的时候可以在软件列表找到软件； apt-get upgrade 是更新本地已安装的软件，要谨慎执行。
感觉不应该执行sudo apt-get upgrade呢
但依然报错E: Unable to locate package squashfuse
我好像犯了一个致命错误
这是我的打包命令
使用uname -a查看当前linux系统架构
其实是armv7l的。难道是因为这个所以才一直报错吗？？
修改命令，重装依赖，接着试
这里可能遇到些下载失败的问题
下载appimage-12.0.1.7z失败
? Get https://github.com/electron-userland/electron-builder-binaries/releases/download/appimage-12.0.1/appimage-12.0.1.7z: dial tcp 13.250.177.223:443: connect: connection timed out

根据链接，把对应的文件下载
新建文件夹appimage
新建文件夹snap、snap-template-electron-4.0-1-armhf
将下载的内容解压到对应的文件夹下
（PS：我感觉并没有用到snap）
重新安装
继续报错
? cannot execute cause=exit status 1
errorOut=/root/.cache/electron-builder/appimage/appimage-12.0.1/linux-arm32/mksquashfs: Compressor “xz” is not supported!
这个问题有点绝，说是appimage的mksquashfs不支持xz
啊？？？
修改打包命令，试试node .electron-vue/build.js && electron-builder --linux
报错变了
Unsupported arch arm stackTrace=
Error: Unsupported arch arm
at archFromString (/root/virt-access/virt-access/node_modules/builder-util/src/arch.ts:43:13)
真是错错无穷
然后我想去看下这一系列打出来的错误内容是什么
打包出来了一个.AppImage文件
???不是一直报错吗，结果打包成功且能运行了。
打包命令：
"linux": “node .electron-vue/build.js && electron-builder --linux --armv7l”,
“armv7l”:“node .electron-vue/build.js && electron-builder --armv7l”,
打包X86时遇到报错

这个报错说得很清楚了
打包时下载snap-template-electron-4.0-2-amd64.tar.7z失败了
下载地址：https://github.com/electron-userland/electron-builder-binaries/releases/download/snap-template-4.0-2/snap-template-electron-4.0-2-amd64.tar.7z
下载后解压放到/snap文件夹下即可
打包就不会报错了
X86解决√
感觉linux下的打包值得再看下
使用electron-packager打包没有遇到报错，但打包出来的无法使用
