踩electron的坑

踩坑系列

背景：在做一个基于electron的一键报税的项目踩过的坑
注：我会持续更新

electron不支持xp

之前有客户使用打包后的electron程序（一键报税），弹出 不是有效的win32程序

第一感觉是系统环境问题，于是google，将得到的方案去尝试无果，于是去github上的electron项目去查找issue，发现了这样的回答

@likenamehaojie Chromium dropped support for Windows XP a long time ago and therefore Electron cannot continue supporting it.Even Microsoft no longer supports the majority of XP installs

Yep, sorry to say that this is a clear “wontfix” from the Electron team.

可自行去electron项目issue搜索xp

electron打印及预览

在查看官方文档后，你会发现BrowserWindow

win.loadURL(url[, options])
url String
options Object (optional)
httpReferrer String (optional) - A HTTP Referrer url.
userAgent String (optional) - A user agent originating the request.
extraHeaders String (optional) - Extra headers separated by “\n”
postData (UploadRawData[] | UploadFile[] | UploadFileSystem[] | UploadBlob[]) - (optional)
baseURLForDataURL String (optional) - Base url (with trailing path separator) for files to be loaded by the data url. This is needed only if the specified url is a data url and needs to load other files.
Same as webContents.loadURL(url[, options]).

通过淘宝镜像安装electron失败

例如这样：

通过给出的链接访问并不存在，那么到淘宝镜像官网查询得出原来是地址出错了。下面给出解决方案

windows

1	set ELECTRON_MIRROR=https://npm.taobao.org/mirrors/electron/

设置环境变量

mac or linux

1	export ELECTRON_MIRROR="https://npm.taobao.org/mirrors/electron/"

重新npm i 你会发现无比畅爽
