nodejs環境を構築する

ここではlinux環境下のnodejs環境の構築だけを紹介します.
NVM
nvmフルネームNode Version Manageは、shellスクリプトによってnodeバージョンの制御を実現します.
インストール
現在のnvmバージョンは0.3.1で、インストール方式は2種類あります.

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.1/install.sh | bash

または

wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.1/install.sh | bash

インストールが完了したら、ホームディレクトリの下に.nvmディレクトリがもう一つあります.隠していますので、ll -aが必要です.
私のログインユーザはrootですので、nvmの位置は/root/.nvm/です.
設定
端末起動時の自動実行設定~/.bashrcファイルに以下のコマンドを追加します.

export NVM_NODEJS_ORG_MIRROR=https://npm.taobao.org/mirrors/node
source /root/.nvm/nvm.sh

端末を再開けて、nvmを入力して車を返します.

[root@localhost html]# nvm

Node Version Manager

Note:  refers to any version-like string nvm understands. This includes:
  - full or partial version numbers, starting with an optional "v" (0.10, v0.1.2, v1)
  - default (built-in) aliases: node, stable, unstable, iojs, system
  - custom aliases you define with `nvm alias foo`

 Any options that produce colorized output should respect the `--no-colors` option.

Usage:
  nvm --help                                Show this message
  nvm --version                             Print out the latest released version of nvm
  nvm install [-s]                 Download and install a , [-s] from source. Uses .nvmrc if available

    --lts                                   When installing, only select from LTS (long-term support) versions
    --lts=                        When installing, only select from versions for a specific LTS line

  nvm uninstall --lts                       Uninstall using automatic LTS (long-term support) alias `lts/*`, if available.
  nvm uninstall --lts=            Uninstall using automatic alias for provided LTS line, if available.
  nvm use [--silent]               Modify PATH to use . Uses .nvmrc if available
    --lts                                   Uses automatic LTS (long-term support) alias `lts/*`, if available.
    --lts=                        Uses automatic alias for provided LTS line, if available.
  nvm exec [--silent]  [] Run  on . Uses .nvmrc if available
    --lts                                   Uses automatic LTS (long-term support) alias `lts/*`, if available.
    --lts=                        Uses automatic alias for provided LTS line, if available.
  nvm run [--silent]  []     Run `node` on  with  as arguments. Uses .nvmrc if available
    --lts                                   Uses automatic LTS (long-term support) alias `lts/*`, if available.
    --lts=                        Uses automatic alias for provided LTS line, if available.
  nvm current                               Display currently activated version
  nvm ls                                    List installed versions
  nvm ls                           List versions matching a given 
  nvm ls-remote                             List remote versions available for install
    --lts                                   When listing, only show LTS (long-term support) versions

  nvm version                      Resolve the given description to a single local version
  nvm version-remote               Resolve the given description to a single remote version
    --lts                                   When listing, only select from LTS (long-term support) versions
    --lts=                        When listing, only select from versions for a specific LTS line
  nvm deactivate                            Undo effects of `nvm` on current shell
  nvm alias []                     Show all aliases beginning with 
  nvm alias                  Set an alias named  pointing to 
  nvm unalias                         Deletes the alias named 
  nvm reinstall-packages           Reinstall global `npm` packages contained in  to current version
  nvm unload                                Unload `nvm` from shell
  nvm which []                     Display path to installed node version. Uses .nvmrc if available
  nvm cache dir                             Display path to the cache directory for nvm
  nvm cache clear                           Empty cache directory for nvm

  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

Note:
  to remove, delete, or uninstall nvm - just remove the `$NVM_DIR` folder (usually `~/.nvm`)

この時はnvm install 7.7.1でnodeをインストールできます.
インストールが完了したら、npmのソースをタオバオソースに設定します.

npm config set registry https://registry.npm.taobao.org

注意、以上が重要です.スライドのためにnpmパッケージを設置します.
