Centos7安装npm|nodejs的步骤

阿里的nodejs网站

https://npm.taobao.org/ 

安装一些必要的库

[root@master ~]# yum install gcc gcc-c++ [hadoop@master Downloads]$ pwd /home/hadoop/Downloads 

下载各个版本的，自己根据项目要求，使用对应的版本。

[hadoop@master Downloads]$ wget https://npm.taobao.org/mirrors/node/latest-v12.x/node-v12.0.0-linux-x64.tar.gz [hadoop@master Downloads]$ wget https://npm.taobao.org/mirrors/node/latest-v11.x/node-v11.0.0-linux-x64.tar.gz [hadoop@master Downloads]$ wget https://npm.taobao.org/mirrors/node/latest-v10.x/node-v10.0.0-linux-x64.tar.gz [hadoop@master Downloads]$ wget https://npm.taobao.org/mirrors/node/latest-v9.x/node-v9.0.0-linux-x64.tar.gz

使用软连接，这样方便日后切换不同的nodejs版本

[hadoop@master nodejs]$ ln -s node-v12.0.0-linux-x64 node [hadoop@master nodejs]$ ls -al total 4 drwxrwxr-x. 3 hadoop hadoop 48 Oct 11 10:12 . drwx------. 75 hadoop hadoop 4096 Oct 11 10:06 .. lrwxrwxrwx. 1 hadoop hadoop 22 Oct 11 10:12 node -> node-v12.0.0-linux-x64 drwxr-xr-x. 6 hadoop hadoop 108 Apr 23 20:38 node-v12.0.0-linux-x64 [root@master ~]# vi /etc/profile #set for nodejs export NODE_HOME=/home/hadoop/nodejs/node export PATH=$NODE_HOME/bin:$PATH [root@master ~]# source /etc/profile [root@master ~]# node -v v12.0.0 [root@master ~]# npm -v 6.9.0 [root@master ~]# 

如果当前目录没有【package.json】文件，那么就需要初始化

[hadoop@master nodejs]$ source /etc/profile [hadoop@master nodejs]$ npm init -y Wrote to /home/hadoop/nodejs/package.json: { "name": "nodejs", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1" }, "keywords": [], "author": "", "license": "ISC" } [hadoop@master nodejs]$ vi package.json [hadoop@master nodejs]$ npm install --registry=https://registry.npm.taobao.org up to date in 0.402s 

这样是将项目声明为私有，就不会报缺少README文件和仓库字段了

安装了cnpm模块后，就可以使用cnpm命令来安装一些其他模块了

[hadoop@master nodejs]$ npm install -g cnpm --registry=https://registry.npm.taobao.org /home/hadoop/nodejs/node-v12.0.0-linux-x64/bin/cnpm -> /home/hadoop/nodejs/node-v12.0.0-linux-x64/lib/node_modules/cnpm/bin/cnpm + cnpm@6.1.0 added 683 packages from 915 contributors in 38.37s [hadoop@master nodejs]$ cnpm install webpack ⠙ [0/1] Installing is-buffer@^1.1.5platform unsupported webpack@4.41.0 › watchpack@1.6.0 › chokidar@2.1.8 › fsevents@^1.2.7 Package require os(darwin) not compatible with your platform(linux) [fsevents@^1.2.7] optional install error: Package require os(darwin) not compatible with your platform(linux) Installed 1 packages Linked 270 latest versions Run 0 scripts Recently updated (since 2019-10-04): 3 packages (detail see file /home/hadoop/nodejs/node_modules/.recently_updates.txt) All packages installed (297 packages installed from npm registry, used 8s(network 8s), speed 638.93kB/s, json 271(546.65kB), tarball 4.46MB) [hadoop@master nodejs]$ npm install --save-dev webpack [hadoop@master nodejs]$ cnpm install webpack-dev-server [hadoop@master nodejs]$ cnpm install --save-dev webpack-cli [hadoop@master nodejs]$ cnpm install webpack-dev-server -g 

永久切换为阿里源

[hadoop@master nodejs]$ npm config set registry https://registry.npm.taobao.org 查询是否切换成功了 [hadoop@master nodejs]$ npm config get registry https://registry.npm.taobao.org/ [hadoop@master nodejs]$ pwd /home/hadoop/nodejs [hadoop@master nodejs]$ find ./ -name webpack*.js 

安装webpack

cnpm install webpack -g 

安装vue脚手架

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，那么就可以启动开发模式了，启动后会卡在这里，并且启动成功后，会打开8080端口，开启一个http的页面，我们访问这个页面，可以看到nodejs的相关目录内容

[hadoop@master nodejs]$ npm run dev > nodejs@1.0.0 dev /home/hadoop/nodejs > webpack-dev-server --inline --progress --config node/lib/node_modules/webpack-dev-server/bin/webpack-dev-server.js 40% building 1/2 modules 1 active /home/hadoop/nodejs/node-v12.0.0-linux-x64/lib/node_modules/webpack-dev-server/client/index.js?http://localhost:8080ℹ ｢wds｣: Project is running at http://localhost:8080/ ℹ ｢wds｣: webpack output is served from / ℹ ｢wds｣: Content not from webpack is served from /home/hadoop/nodejs ｢wdm｣: Hash: f13ad31a69df887be4b7 Version: webpack 4.41.0 Time: 518ms Built at: 10/11/2019 2:24:38 PM Asset Size Chunks Chunk Names main.js 365 KiB main [emitted] main Entrypoint main = main.js [0] multi ./node-v12.0.0-linux-x64/lib/node_modules/webpack-dev-server/client?http://localhost:8080 ./src 40 bytes {main} [built] [./node-v12.0.0-linux-x64/lib/node_modules/webpack-dev-server/client/clients/SockJSClient.js] 3.33 KiB {main} [built] [./node-v12.0.0-linux-x64/lib/node_modules/webpack-dev-server/client/index.js?http://localhost:8080] ./node-v12.0.0-linux-x64/lib/node_modules/webpack-dev-server/client?http://localhost:8080 4.29 KiB {main} [built] [./node-v12.0.0-linux-x64/lib/node_modules/webpack-dev-server/client/overlay.js] 3.51 KiB {main} [built] [./node-v12.0.0-linux-x64/lib/node_modules/webpack-dev-server/client/socket.js] 1.53 KiB {main} [built] [./node-v12.0.0-linux-x64/lib/node_modules/webpack-dev-server/client/utils/createSocketUrl.js] 2.89 KiB {main} [built] [./node-v12.0.0-linux-x64/lib/node_modules/webpack-dev-server/client/utils/getCurrentScriptSource.js] 658 bytes {main} [built] [./node-v12.0.0-linux-x64/lib/node_modules/webpack-dev-server/client/utils/log.js] 964 bytes {main} [built] [./node-v12.0.0-linux-x64/lib/node_modules/webpack-dev-server/client/utils/reloadApp.js] 1.59 KiB {main} [built] [./node-v12.0.0-linux-x64/lib/node_modules/webpack-dev-server/client/utils/sendMessage.js] 402 bytes {main} [built] [./node-v12.0.0-linux-x64/lib/node_modules/webpack-dev-server/node_modules/ansi-html/index.js] 4.16 KiB {main} [built] [./node-v12.0.0-linux-x64/lib/node_modules/webpack-dev-server/node_modules/ansi-regex/index.js] 135 bytes {main} [built] [./node-v12.0.0-linux-x64/lib/node_modules/webpack-dev-server/node_modules/html-entities/index.js] 231 bytes {main} [built] [./node-v12.0.0-linux-x64/lib/node_modules/webpack-dev-server/node_modules/strip-ansi/index.js] 161 bytes {main} [built] [./node_modules/webpack/hot sync ^\.\/log$](webpack)/hot sync nonrecursive ^\.\/log$ 170 bytes {main} [built] + 17 hidden modules ERROR in Entry module not found: Error: Can't resolve './src' in '/home/hadoop/nodejs' ERROR in multi ./node-v12.0.0-linux-x64/lib/node_modules/webpack-dev-server/client?http://localhost:8080 ./src Module not found: Error: Can't resolve './src' in '/home/hadoop/nodejs' @ multi ./node-v12.0.0-linux-x64/lib/node_modules/webpack-dev-server/client?http://localhost:8080 ./src main[1] ℹ ｢wdm｣: Failed to compile. 

cd 命令进入eclipse/idea创建的工程目录

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

安装项目依赖
一定要从官方仓库安装，npm 服务器在国外所以这一步安装速度会很慢。这个install的命令一定要在eclipse，或者idea的前段代码所在路径进行安装

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

不要从国内镜像cnpm安装(会导致后面缺了很多依赖库)

[hadoop@master vuesys]$ cnpm install 

如果是已经存在的项目（package.json直接是已经存在的），那么可以尝试直接运行：

[hadoop@master nodejs]$ npm run dev [hadoop@master vuesys]$ ls -al total 120 drwxr-xr-x. 9 hadoop hadoop 4096 Oct 11 15:28 . drwxrwxr-x. 25 hadoop hadoop 4096 Oct 11 14:43 .. -rw-r--r--. 1 hadoop hadoop 337 Oct 11 14:43 .babelrc drwxr-xr-x. 2 hadoop hadoop 200 Oct 11 14:43 build -rw-r--r--. 1 hadoop hadoop 2371 Oct 11 14:43 CHANGELOG.md drwxr-xr-x. 2 hadoop hadoop 78 Oct 11 14:43 config -rw-r--r--. 1 hadoop hadoop 147 Oct 11 14:43 .editorconfig -rw-r--r--. 1 hadoop hadoop 74 Oct 11 14:43 .eslintignore -rw-r--r--. 1 hadoop hadoop 576 Oct 11 14:43 .eslintrc.js -rw-r--r--. 1 hadoop hadoop 212 Oct 11 14:43 .gitignore -rw-r--r--. 1 hadoop hadoop 2670 Oct 11 14:43 gulpfile.js drwxr-xr-x. 2 hadoop hadoop 62 Oct 11 15:20 .idea -rw-r--r--. 1 hadoop hadoop 977 Oct 11 14:43 index.html -rw-r--r--. 1 hadoop hadoop 1057 Oct 11 14:43 LICENSE drwxrwxr-x. 1150 hadoop hadoop 36864 Oct 11 15:28 node_modules ---》新生成的模块目录 -rw-r--r--. 1 hadoop hadoop 3082 Oct 11 14:43 package.json -rw-r--r--. 1 hadoop hadoop 223 Oct 11 14:43 .postcssrc.js -rw-r--r--. 1 hadoop hadoop 8 Oct 11 14:43 README.md drwxr-xr-x. 12 hadoop hadoop 188 Oct 11 14:43 src drwxr-xr-x. 5 hadoop hadoop 46 Oct 11 14:43 static drwxr-xr-x. 4 hadoop hadoop 29 Oct 11 14:43 test -rw-rw-r--. 1 hadoop hadoop 335 Oct 11 15:18 vuesys.iml 

安装 vue 路由模块vue-router和网络请求模块vue-resource

cnpm install vue-router vue-resource --save 

启动项目

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

安装一下这个依赖到工程开发环境

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 '模块名'
那就安装
cnpm install 模块名 --save-dev(关于环境的，表现为npm run dev 启动不了)
cnpm install 模块名 --save(关于项目的，比如main.js，表现为npm run dev 成功之后控制台报错)
比如escape-string-regexp、strip-ansi、has-ansi、is-finite、emojis-list

输入完命令会自动打开浏览器，如果默认打开 IE 不行（这里所有的操作，都是在idea，eclipse的目录中完成的）
