Electron：运行npm run build构建环境失败解决方案

摘要

从GitLab上拉取项目代码后，运行命令npm run build构建electron打包环境时，由于某些原因（可能被某些墙阻止等），构建环境失败，出现超时错误。错误代码如下：

解决方案

为了更好更快的解决构建环境问题，需要我们手动下载好electron环境的压缩资源包等，构建好的打包缓存环境（存放手动下载资源包前，优先清除cache的缓存记录）。

方案具体步骤

1. 清除electron和electron-builder的cache缓存记录（删除文件夹中旧的缓存资源包）。

• electron缓存资源地址：~/AppData/Local/electron/Cache

• electron-builder缓存资源地址：~/AppData/Local/electron-builder/Cache

2. 根据错误提示一步一步的手动下载资源包（资源包版本直接下载当前提示的可用版本，具体类似下图所示下载链接）。
   

• 下载好缓存资源包后，存储到对应的cache文件中。

  • electron文件存储方式：
    

  • electron-builder文件存储方式：
    

  • nsis文件存储方式：
    

  • winCodeSign存储方式：
    

3. 重新运行命令npm run build
