這里僅介紹linux環(huán)境下nodejs環(huán)境的搭建
NVM
nvm全稱Node Version Manage，通過shell腳本實現(xiàn)對node版本控制
安裝
當(dāng)前nvm版本是0.33.1，安裝方式有倆種
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.1/install.sh | bash
或者
wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.1/install.sh | bash
安裝完成之后會在家目錄下多一個.nvm目錄，由于是隱藏的，需要ll -a才能看到
我的登錄用戶是root，故nvm的位置是/root/.nvm/
配置
配置終端啟動時自動執(zhí)行
在~/.bashrc文件中添加以下命令：
export NVM_NODEJS_ORG_MIRROR=https://npm.taobao.org/mirrors/node
source /root/.nvm/nvm.sh
重新打開終端，輸入nvm回車
[root@localhost html]# nvm
Node Version Manager
Note: <version> 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] <version> Download and install a <version>, [-s] from source. Uses .nvmrc if available
--reinstall-packages-from=<version> When installing, reinstall packages installed in <node|iojs|node version number>
--lts When installing, only select from LTS (long-term support) versions
--lts=<LTS name> When installing, only select from versions for a specific LTS line
nvm uninstall <version> Uninstall a version
nvm uninstall --lts Uninstall using automatic LTS (long-term support) alias `lts/*`, if available.
nvm uninstall --lts=<LTS name> Uninstall using automatic alias for provided LTS line, if available.
nvm use [--silent] <version> Modify PATH to use <version>. Uses .nvmrc if available
--lts Uses automatic LTS (long-term support) alias `lts/*`, if available.
--lts=<LTS name> Uses automatic alias for provided LTS line, if available.
nvm exec [--silent] <version> [<command>] Run <command> on <version>. Uses .nvmrc if available
--lts Uses automatic LTS (long-term support) alias `lts/*`, if available.
--lts=<LTS name> Uses automatic alias for provided LTS line, if available.
nvm run [--silent] <version> [<args>] Run `node` on <version> with <args> as arguments. Uses .nvmrc if available
--lts Uses automatic LTS (long-term support) alias `lts/*`, if available.
--lts=<LTS name> Uses automatic alias for provided LTS line, if available.
nvm current Display currently activated version
nvm ls List installed versions
nvm ls <version> List versions matching a given <version>
nvm ls-remote List remote versions available for install
--lts When listing, only show LTS (long-term support) versions
nvm ls-remote <version> List remote versions available for install, matching a given <version>
--lts When listing, only show LTS (long-term support) versions
--lts=<LTS name> When listing, only show versions for a specific LTS line
nvm version <version> Resolve the given description to a single local version
nvm version-remote <version> Resolve the given description to a single remote version
--lts When listing, only select from LTS (long-term support) versions
--lts=<LTS name> When listing, only select from versions for a specific LTS line
nvm deactivate Undo effects of `nvm` on current shell
nvm alias [<pattern>] Show all aliases beginning with <pattern>
nvm alias <name> <version> Set an alias named <name> pointing to <version>
nvm unalias <name> Deletes the alias named <name>
nvm reinstall-packages <version> Reinstall global `npm` packages contained in <version> to current version
nvm unload Unload `nvm` from shell
nvm which [<version>] 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
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
Note:
to remove, delete, or uninstall nvm - just remove the `$NVM_DIR` folder (usually `~/.nvm`)
這個時候nvm install 7.7.1即可安裝node
安裝完成之后，再配置下npm的源為淘寶源
npm config set registry https://registry.npm.taobao.org
注意，以上很重要，為了絲滑的安裝npm包
