javascript – 安装电子模块时的节点模块版本冲突

我正在尝试制作一个从我的串口读取数据的Electron应用程序(https://electron.atom.io/).我一般都是网络技术的新手,我知道一些javascript,但我是一个人.

所以我从github快速入手,跑了

npm install && npm start

随着这个轻松工作,我尝试安装和运行serialport

npm install serialport

使用测试文件安装并运行正常,我尝试将两者结合起来并在index.html文件中放置require(‘serialport’).有了这个,我得到这个错误：

Uncaught Error: The module '/home/user/Documents/Programing/Git/Arduino-mpu6050/electron-quick-start/node_modules/serialport/build/Release/serialport.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 51. This version of Node.js requires
NODE_MODULE_VERSION 53. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or`npm install`).

    at Object.<anonymous> (/home/user/Documents/Programing/Git/Arduino-mpu6050/electron-quick-start/node_modules/serialport/lib/bindings.js:3:35)

任何想法如何解决它？我没有使用两个不同版本的Node,为什么我会收到此错误.

系统OS信息：

distributor ID: Ubuntu
Description:    Ubuntu 16.04.2 LTS
Release:    16.04
Codename:   xenial

解决方法:

当发生这种类型的版本不匹配时,您可以选择具有目标节点版本的电子分布,也可以重建npm包.由于Electron的发行版已跳过使用NODE_MODULE_VERSION 51配置的Node v7.0.0(并跳转到v7.4.0),因此您必须重建serialport包.

在你的应用程序目录中(package.json所在的目录),

1.安装电子重建

npm install –save-dev electron-rebuild

2.重建

./node_modules/.bin/electron-rebuild

或者,即使是更好的选择 – 从一开始就设置环境变量.

# Electron's version.
export npm_config_target=1.6.1
# The architecture of Electron, can be ia32 or x64.
export npm_config_arch=x64
export npm_config_target_arch=x64
# Download headers for Electron.
export npm_config_disturl=https://atom.io/download/electron
# Tell node-pre-gyp that we are building for Electron.
export npm_config_runtime=electron
# Tell node-pre-gyp to build module from source code.
export npm_config_build_from_source=true
# Install all dependencies, and store cache to ~/.electron-gyp.
HOME=~/.electron-gyp npm install
