摘要

從GitLab上拉取項目代碼后，運行命令npm run build構建electron打包環(huán)境時，由于某些原因（可能被某些墻阻止等），構建環(huán)境失敗，出現(xiàn)超時錯誤。錯誤代碼如下：

解決方案

為了更好更快的解決構建環(huán)境問題，需要我們手動下載好electron環(huán)境的壓縮資源包等，構建好的打包緩存環(huán)境（存放手動下載資源包前，優(yōu)先清除cache的緩存記錄）。

方案具體步驟

1. 清除electron和electron-builder的cache緩存記錄（刪除文件夾中舊的緩存資源包）。

• electron緩存資源地址：~/AppData/Local/electron/Cache

• electron-builder緩存資源地址：~/AppData/Local/electron-builder/Cache

2. 根據(jù)錯誤提示一步一步的手動下載資源包（資源包版本直接下載當前提示的可用版本，具體類似下圖所示下載鏈接）。
   

• 下載好緩存資源包后，存儲到對應的cache文件中。

  • electron文件存儲方式：
    

  • electron-builder文件存儲方式：
    

  • nsis文件存儲方式：
    

  • winCodeSign存儲方式：
    

3. 重新運行命令npm run build
