I want to run an NVM command from bash script i.e. nvm use 0.12.7 . So, I have written in bash file: #!/bin/bash . ~/.nvm/nvm.sh nvm use 0.12.7 And then run the command in the terminal as sudo ./script.sh (script.sh is my bash file where above code is written).

1.去官网下载最新的安装包 https://github.com/coreybutler/nvm-windows/releases    在安装管理工具之前一定要把电脑中的node卸载干净,不然会有坑! 下载傻瓜式一键安装,要注意安装路径,不能有空格! 2.安装检测 新打开cmd 输入 nvm 如何出现错误,建议重新安装,或者根据错误自行Google 3.操作nvm 每个命令的用法和说明 4.安装node nvm install latest 先安装最新的 在安装项目需要的 执行mvn ls,可以查看安装的node版本 想用哪个就 nvm use xxx 5.执行cmd要用管理员模式运行! 感谢提供的帮助: https://www.jianshu.com/p/324044f2f542 来源: https://www.cnblogs.com/xiaxuening/p/11649273.html

Node.js 介绍和特点

1.node.js是什么 node.js不是一门语言,而是一个开发平台,是一个基于 Chrome V8 引擎的 JavaScript 运行环境。 何为开发平台:有对应的语言和实现特定功能的api 2.node.js的特点 1.事件驱动 2.非阻塞式 I/O 的模型 3.单线程 4.拥有世界上最大的开源生态系统-npm 3.node版本 LTS版本:长期支持版,即稳定版 Current版本:最新版 安装node后在cmd下运行node -v即可查看安装的node.js版本 如果安装成功却提示node不是内部或者外部的命令。则需要手动配置环境变量 4.配置环境变量 为什么要配置环境变量:一般情况下,cmd环境想要运行一个文件,例如node.exe,那么对应的路径下必须有node.exe这个文件才能启动,否则就会提示命令不存在。 配置环境变量就是告诉电脑,如果我们输入的命令在当前路径下没有对应的执行文件,那么就去其他路径下查看,配置环境变量也就是添加一个可供查找的绝对路径 如何配置环境变量: 右键计算机>属性>系统高级设置>高级>环境变量 选择Path这个变量名,对应的变量值是有若干的路径组成的每个路径用";"隔开,添加时也记得加 分号 ,这里node.js安装是已经自动添加了环境变量,所以里面已经有node.js的路径了,如果没有,就要手动添加 5.node.js多版本共存 node

Node.js - Configuring $NODE_PATH with NVM

社会主义新天地 提交于 2019-11-30 21:38:28
问题 On my way setting up Node.js with NVM , I stumbled upon an error when using Yeoman . I got the error Cannot find module 'yeoman-generator' After some research I found this post on StackOverflow, which is also about my problem. Now I tried to do so, but the problem I have is, that I want to use different versions of Node.js over the system with the use of NVM. Now is it possible to change the $NODE_PATH dynamically, if the Node.js version changes with the help of NVM? Because my $NODE_PATH is

Is there any way how to run “nvm use” automatically in “prestart” npm script?

和自甴很熟 提交于 2019-11-30 09:08:43
I would like to have automatically invoke "nvm use" when I run "npm start". So I come up with this solution: package.json "scripts": { "prestart": "sh test.sh", "start": "nodemon index.js" } .nvmrc 4 test.sh #!/bin/bash if [ -d ~/.nvm ] then source ~/.nvm/nvm.sh nvm use fi This works and switch between nvm versions console output is: > sh test.sh Found '/my-user-path/.nvmrc' with version <4> Now using node v4.2.2 (npm v2.14.7) > app@1.0.0 start /app-path/ > nodemon index.js But when I call form index.js "console.log(process.versions);" nvm script is executed probably in different process so

0. 前言 licode官网文档安装教程十分简单, 但是实际搭建过程是很艰辛的. 官方文档没有提示说会遇到什么样的问题, 实际过程中可能遇到各种各样的问题, 在解决的时候费时费力, 我就总结一下自己在安装搭建过程中遇到的问题. 注: 最大的问题就是网络问题, 整个安装过程是边下载资源边安装的, 资源基本都是国外的, 因为墙的缘故, 可能会遇到想不到的错误. 1. 环境 系统: ubuntu16.04.6 ( ubuntu14.04.6也可以 ) 用户: root 执行时最好加 sudo 官方安装教程地址: https://licode.readthedocs.io/en/master/from_source/ 2. 搭建 下面是我引用licode官方教程中一些主要步骤内容 Clone Licode Let's start by cloning the Licode repository git clone https://github.com/lynckia/licode.git cd licode The repository contains scripts for the rest of the steps of this guide.
