Centos7安裝npm|nodejs的步驟

安裝一些必要的庫

[root@master ~]# yum install gcc gcc-c++

[hadoop@master Downloads]$ pwd
/home/hadoop/Downloads

下載下傳各個版本的，自己根據項目要求，使用對應的版本。

使用軟連接配接，這樣友善日後切換不同的nodejs版本

[hadoop@master nodejs]$ ln -s node-v12.0.0-linux-x64 node
[hadoop@master nodejs]$ ls -al

查詢是否切換成功了
[hadoop@master nodejs]$ npm config get registry

[hadoop@master nodejs]$ pwd

安裝webpack

cnpm install webpack -g

安裝vue腳手架

npm install vue-cli -g

[hadoop@master nodejs]$ cnpm install webpack
[hadoop@master nodejs]$ cnpm install

[hadoop@master nodejs]$ cnpm run dev

如果一切正常了，那麼就可以啟動開發模式了，啟動後會卡在這裡，并且啟動成功後，會打開8080端口，開啟一個http的頁面，我們通路這個頁面，可以看到nodejs的相關目錄内容

[hadoop@master nodejs]$ npm run dev

cd 指令進入eclipse/idea建立的工程目錄

[hadoop@master vuesys]$ pwd
/home/hadoop/IdeaProjects/vuesys

安裝項目依賴

一定要從官方倉庫安裝，npm 伺服器在國外是以這一步安裝速度會很慢。這個install的指令一定要在eclipse，或者idea的前段代碼所在路徑進行安裝

[hadoop@master vuesys]$ pwd
/home/hadoop/IdeaProjects/vuesys
[hadoop@master vuesys]$ npm install

不要從國内鏡像cnpm安裝(會導緻後面缺了很多依賴庫)

[hadoop@master vuesys]$ cnpm install

如果是已經存在的項目（package.json直接是已經存在的），那麼可以嘗試直接運作：

[hadoop@master nodejs]$ npm run dev

[hadoop@master vuesys]$ ls -al

安裝 vue 路由子產品vue-router和網絡請求子產品vue-resource

cnpm install vue-router vue-resource --save

啟動項目

npm run dev

[hadoop@master nodejs]$ npm update -g
[hadoop@master nodejs]$ npm update vue-cli

安裝一下這個依賴到工程開發環境

cnpm install opn --save-dev
cnpm install webpack-dev-middleware --save-dev
cnpm install express --save-dev
cnpm install compression --save-dev
cnpm install sockjs --save-dev
cnpm install spdy --save-dev
cnpm install http-proxy-middleware --save-dev
cnpm install serve-index --save-dev
cnpm install connect-history-api-fallback --save-dev
cnpm install babel-helpers --save-dev
cnpm install babel-traverse --save-dev
cnpm install json5 --save-dev

遇到

Module build failed: Error: Cannot find module '子產品名'

那就安裝

cnpm install 子產品名 --save-dev(關于環境的，表現為npm run dev 啟動不了)

cnpm install 子產品名 --save(關于項目的，比如main.js，表現為npm run dev 成功之後控制台報錯)

比如escape-string-regexp、strip-ansi、has-ansi、is-finite、emojis-list

輸入完指令會自動打開浏覽器，如果預設打開 IE 不行（這裡所有的操作，都是在idea，eclipse的目錄中完成的）

[hadoop@master nodejs]$ npm run dev
