Windows10搭建Node.js环境
准备系统的学习前端，试着把学习过程记录下来，下面是我搭建node.js环境的过程：
-使用git安装nvmw
1.打开git bash
$cd d:
$mkdir git
$cd git
$git clone https://github.com/cnpm/nvmw.git2.配置环境变量
3.打开命令行或者power shell
Windows PowerShell

PS C:\Users\Bingo> nvmw
Node Version Manager for Windows
Usage:
nvmw help Show this message
nvmw install [version] [arch] Download and install a [version]
for [arch] architecture (optional)
nvmw uninstall [version] Uninstall a [version]
nvmw use [version] Modify PATH to use [version]
nvmw ls List installed versions
Example:
nvmw install v0.10.21 Install a specific version number of node.js
nvmw use v0.10.21 Use the specific version
nvmw install iojs Install the latest version of io.js
nvmw install iojs-v1.0.2 Install a specific version number of io.js
nvmw use iojs-v1.0.2 Use the specific version io.js
nvmw install v0.10.35 x86 Install a 32-bit version-使用nvmw安装任意版本的node
关于nodejs版本https://nodejs.org/zh-cn/download/releases/
nvmw install 0.12.0这个命令会报404文件下载不了
PS C:\Users\Bingo> nvmw install 0.12.0
Start installing node/v0.12.0 (x64) to D:\git\nvmw\v0.12.0
Download from http://npm.taobao.org/mirrors/node/v0.12.0/win-x64/node.exe, and save it as D:\git\nvmw\v0.12.0\node.exe
404 Not Found
Download D:\git\nvmw\v0.12.0\node.exe from http://npm.taobao.org/mirrors/node/v0.12.0/win-x64/node.exe failed上面有个链接
http://npm.taobao.org/mirrors/node/v0.12.0/win-x64/node.exe直接按照上面的链接下载不了，应该是路径有问题
又从网上查到了个和我不一样错误https://segmentfault.com/q/1010000004295724
C:\Users\Administrator>nvmw install 0.12.9
Start installing node/v0.12.9 (x64) to D:\Portable\nvmw\v0.12.9
Download from http://npm.taobao.org/mirrors/node/v0.12.9/x64/node.exe, and save
it as D:\Portable\nvmw\v0.12.9\node.exe
Done
Start install npm
Download file from https://raw.githubusercontent.com/joyent/node/v0.12.9/deps/np
m/package.json
package.json
node v0.12.9 does not include npmhttp://npm.taobao.org/mirrors/node/v0.12.9/x64/node.exe这个里面的链接 是可以在下载的，我把我的win-x64改成 x64也可以下载了
在安装的nvmw文件夹下的nvmw.bat 126行左右有代码修改如下：
if %NODE_TYPE% == iojs (
set DIST_URL=%%
if %ARCH% == x32 (
set NODE_EXE_URL=%NVMW_IOJS_ORG_MIRROR%/%NODE_VERSION%/win-x86/iojs.exe
) else (
set NODE_EXE_URL=%NVMW_IOJS_ORG_MIRROR%/%NODE_VERSION%/win-x64/iojs.exe
)
) else (
if %ARCH% == x32 (
set NODE_EXE_URL=%NVMW_NODEJS_ORG_MIRROR%/%NODE_VERSION%/win-x86/node.exe
) else (
set NODE_EXE_URL=%NVMW_NODEJS_ORG_MIRROR%/%NODE_VERSION%/win-x64/node.exe
)
)
把上面的win-x64 改成 x64 就可以了
PS C:\Users\Bingo> nvmw install 0.12.0

Start unzip "D:\git\nvmw\v0.12.0\npm.zip" to "D:\git\nvmw\v0.12.0"
系统找不到指定的文件。
D:\git\nvmw\v0.12.0\npm-2.5.1
移动了 1 个目录。
已复制 1 个文件。
D:\git\nvmw\v0.12.0
npm install ok
Finished
Now using node v0.12.0 x64经我测试下面这种版本号下载的时候需要修改链接http://npm.taobao.org/mirrors/node/v0.12.0/x64/node.exe
如果下载另一种版本的 就不用修改链接 直接用http://npm.taobao.org/mirrors/node/v7.7.3/win-x64/node.exe
我还不了解为什么会这样
最后配置环境变量path增加
D:\git\nvmw\v0.12.0打开命令行或power shell
