Make sure that /usr/local/bin is in your $PATH.
$ which node
/Users/mxr/.nvm/versions/node/v7.10.0/bin/node
上述打印标明之前使用nvm管理node,故使用以下命令升级node至稳定版本:
$ nvm install stable

nvm install 4.2.2 # 安装 4.2.2 版本
nvm install 0.12.7 # 安装 0.12.7 版本
# 特别说明:以下模块安装仅供演示说明,并非必须安装模块
nvm use 4 # 切换至 4.2.2 版本
npm install -g mz-fis # 安装 mz-fis 模块至全局目录,安装完成的路径是 /Users/<你的用户名>/.nvm/versions/node/v0.12.7/lib/mz-fis
nvm use 0 # 切换至 0.12.7 版本
npm install -g react-native-cli #安装 react-native-cli 模块至全局目录,安装完成的路径是 /Users/<你的用户名>/.nvm/versions/node/v4.2.2/lib/react-native-cli
nvm alias default 0.12.7 #设置默认 node 版本为 0.12.7
nvm uninstall v6.6.0 #删除指定版本 node
升级 Nodejs
后需要重新安装weex-toolkit
$ vim /etc/profile
然后全局安装 weex-toolkit
。
npm install weex-toolkit -g
创建一个空的模板项目 Weex + Vue.js
$ weex create awesome-app
$ cd awesome-app
Inside this directory, you can run several commands:
npm start Starts the development server for you to preview your weex page on browser You can also scan the QR code using weex playground to preview weex page on native
npm run dev Open the code compilation task in watch mode
npm run ios (Mac only, requires Xcode) Starts the development server and loads your app in an iOS simulator
npm run android (Requires Android build tools) Starts the development server and loads your app on a connected Android device or emulator
npm run pack:ios (Mac only, requires Xcode) Packaging ios project into ipa package
npm run pack:android (Requires Android build tools) Packaging android project into apk package
npm run pack:web
Packaging html5 project into web/build
folder
npm run test Starts the test runner
To get started:
cd awesome-app npm start
Enjoy your hacking time!
This boilerplate is targeted towards large, serious projects and assumes you are somewhat familiar with Webpack and weex-loader
.
To use this template, scaffold a project with weexpack v1.1.1+.
$ npm install -g weex-toolkit
$ weex create my-project # default will create the webpack template
$ cd my-project && npm start
Take sass
for example:
$ npm i node-sass sass-loader --save
Then, you just need to change the style
tag as: <style lang="sass"><style>
.
See How-to-create-your-own-template.
@weex-cli/doctor 模块提供对本地开发环境的检查,可使用如下命令启动:
$ weex doctor
该命令会检查你的本地开发环境,你可根据提示对你的开发环境进行调整,以便进行weex页面的开发工作。

第一步,先查看本机node.js版本:
$ node -v
第二步,清除node.js的cache:
$ sudo npm cache clean -f
第三步,安装 n 工具,这个工具是专门用来管理node.js版本的,别怀疑这个工具的名字,是他是他就是他,他的名字就是 "n"
$ sudo npm install -g n
第四步,安装最新版本的node.js
$ sudo n stable
第五步,再次查看本机的node.js版本:
$ node -v
第六步,更新npm到最新版:
$ sudo npm install npm@latest -g
第七步,验证
$ node -v
$ npm -v
$ npm install
$ npm audit
$ npm audit fix
