NVM

  • Node Version Manage
    需要在同一電腦上面做不同板本的node切換，此時就需要用到nvm

如何安裝

  • 使用wget如下

    1
    wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.31.6/install.sh | bash

  • 安裝完成會在使用者目錄產生.nvm目錄

    drwxr-xr-x   3 root root 4096 Aug 30 05:45 .node-gyp
    drwxr-xr-x 123 root root 4096 Aug 30 05:40 .npm
    drwxr-xr-x   4 root root 4096 Aug 30 06:53 .nvm
    -rw-r--r--   1 root root  140 Apr 19  2012 .profile

  • 若建入nvm無反應，則先source .nvm/nvm.sh，就可以使用nvm指令

    1
    . .nvm/nvm.sh

  • example

    Example:
      nvm install v0.10.32                  Install a specific version number
      nvm use 0.10                          Use the latest available 0.10.x release
      nvm run 0.10.32 app.js                Run app.js using node v0.10.32
      nvm exec 0.10.32 node app.js          Run `node app.js` with the PATH pointing to node v0.10.32
      nvm alias default 0.10.32             Set default node version on a shell

使用nvm安裝node特定版本

  • nvm ls-remote
    List remote versions available for install
    查看可以使用node版本

             v4.2.0   (LTS: Argon)

如何build addon c++

example / 1_hello_world

  • node-addon-examples
  • 於1_hello_world/node_0.10目錄內

  • 安裝build code需要的gyp工具

    1
    sudo npm install node-gyp -g

  • 安裝此package需要的相關套件

    1
    npm install

  • node-gyp rebuild

binding.gyp

如何cross compile arm

  • 需要先export用到的env

    export AR=/opt/hisi-linux/x86-arm/arm-hisiv200-linux/target/bin/arm-hisiv200-linux-ar
    export CC=/opt/hisi-linux/x86-arm/arm-hisiv200-linux/target/bin/arm-hisiv200-linux-gcc
    export CXX=/opt/hisi-linux/x86-arm/arm-hisiv200-linux/target/bin/arm-hisiv200-linux-g++
    export LINK=/opt/hisi-linux/x86-arm/arm-hisiv200-linux/target/bin/arm-hisiv200-linux-g++

  • 指定cpu為arch為arm且build

    1
    node-gyp --arch arm configure build

遇到問題

目前使用docker ubuntu 12.04 32bit

  • 使用nvm install v0.10.43之後

  • 發現nvm安裝64bit node,,怪怪的

改為使用docker ubuntu 14.04 64bit

  • docker 64bit os
