Ionic3项目创建

Ionic3项目创建

本地环境：
$ cordova -v9.0.0 ([email protected])
$ ionic -v3.12.0
$ npm -v6.10.3
$ node -v12.9.1

步骤
一：进入项目目录
二：ionic start 项目名 --no-deps
【–no-deps是跳过npm安装依赖，因为翻不了墙 先跳过之后淘宝镜像安装】
后续需要选择tabs 以及是否连接git
三：cd 进入项目根目录
四：cnpm install 【安装依赖】
此处报错：

解决方法：1、删除项目node_modules下的node-sass@~4.5.3或其他版本文件
2、终端输入 cnpm install [email protected]
3、启动项目okk

解释参考：
I’m using OSX latest version(10.14.4 (18E226)) and node 12.
While using node-sass 4.11, I had g++ error(…/src/create_string.cpp:17:25: error: no matching constructor for initialization of ‘v8::String::Utf8Value’) while trying npm install, npm rebuild(link) which did not work.
I solved this by updating node-sass to 4.12(npm install node-sass), as the github issue on the node-sass says that support for node 12 is implemented in 4.12 version.

这是俺第一次通过外文网站解决bug 因为懒得看英文百度白天无果 果然学英语还是有用的…
