resolvent

1. Resolve the slow download of Electron
   New Project Root Directory .npmrc File, add the following environment variables:

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

   This item sets the Electron image source as Taobao image source.

2. Solve the slow download of NSIS and winCodeSign
   Draw like a cat, in .npmrc Same settings in ELECTRON_BUILDER_BINARIES_MIRROR Image source address. cnpm also provides the corresponding image source:

the selected readings

When writing this draft article, Taobao ELECTRON_BUILDER_BINARIES_MIRROR The image source is always hung up. If you use it, you will find that NSIS and winCodeSign cannot be pulled down at all.

On April 25, 2020, a brother and I commented on the corresponding issues#1539 Then a big brother fixed the problem.

Therefore, the measure taken at that time was to manually download the file and place it in the Electron builder folder, which is also necessary to know.

• Nsis storage location

   C:\Users\admin\AppData\Local\electron-builder\Cache\winCodeSign

  

• WinCodeSign storage location

   C:\Users\admin\AppData\Local\electron-builder\Cache\winCodeSign

  

Manually download the files of the corresponding version and unzip them to these two folders.
