CentOS7安装配置Nodejs

 为防止gulp与node版本冲突，本文只下载node 10.x版本，否则到时候报错

本人是报错后才修改的，原本使用的是node

1. 官网获取LTS版linux64的node10.x下载地址，或淘宝镜像，自己选一个v10的，建议去淘宝的，比较快
2. 下载

   cd /opt/
   wget https://npm.taobao.org/mirrors/node/latest-v10.x/node-v10.22.0-linux-x64.tar.xz

    

3. 解压

   tar xvJf node-v10.22.0-linux-x64.tar.xz

   mv node-v10.22.0-linux-x64 /usr/local/nodejs

    

4. 配置环境变量

   vim /etc/profile

   末尾添加

   # nodejs
   export NODE_HOME=/usr/local/nodejs
   export PATH=$PATH:${NODE_HOME}/bin

    

5. 生效

   source /etc/profile

    

6. 检查是否安装成功

   node -v
   npm -v

   

    

7. npm换源

   npm config set registry https://registry.npm.taobao.org
   
   #如果只是临时改变源，可以这样
   npm --registry=https://registry.npm.taobao.org

    淘宝源有时候会有问题，还是需要切换到官方源

   npm config set registry http://registry.npmjs.org

    

8. 更新

   npm install -g npm

    

9. 解决npm权限问题

   npm config -g set unsafe-perm

    

10. 解决node-sass 安装失败

    # 设置全局镜像源 之后再涉及到 node-sass 的安装时就会从淘宝镜像下载。
    npm config set sass_binary_site https://npm.taobao.org/mirrors/node-sass/
