python - Windows 上的 Electron 重建串行端口错误

Question

我正在开发一个项目 Electron和 serialport 。

串行端口库不会自动工作。在 Readme.md 中搜索，我发现需要使用 electron-rebuild 重新编译 NodeJS 版本的 Electron 库。图书馆。 (在 package.json 中插入此脚本:"install": "electron-rebuild")。

Electron 重建需要在计算机中安装Python，所以我通过windows-build-tools安装。 (全局安装)

所以现在当我运行命令 npm install 时，我收到此错误:

如何编译这个库？提前致谢!

Answer 1

Install windows build tools

npm install --global --production windows-build-tools 

or

 npm --add-python-to-path='true' --debug install --global windows-build-tools

then set path variables

setx PYTHON "%USERPROFILE%\.windows-build-tools/python27/python.exe"

set PYTHON

set PYTHON helps you check if its set up correctly.

This is not enough install electron rebuild globally in your project files

npm install -g electron-prebuilt  

npm install --save serialport

We have to rebuild serialport to work with electron. To do this, we need to install electron-rebuild:

npm install --save-dev electron-rebuild 

最后一步是在应用程序的根目录中再次运行 electro-rebuild:

 ./node_modules/.bin/electron-rebuild
