Windows 下npm升级方法

Windows 下npm升级方法

本来是尝试在windows下用命令升级nodejs，结果发现浪费了挺大劲，升级的是npm，已经记录的差不多了，有不舍得删，特此另起一篇记录吧。

1. 首先更新npm为淘宝源，实在是等不起

npm install -g cnpm --registry=https://registry.npm.taobao.org

2. 安装一个叫npm-windows-upgrade的包

cnpm install npm-windows-upgrade

3. 尝试执行npm-windows-upgrade

npm-windows-upgrade

提示内容的大意是没有权限，请一管理员身份运行

4. 以管理员身份运行powershell（win+x按键）

继续执行上述命令，提示如下内容

npm-windows-upgrade v6.0.1

Scripts cannot be executed on this system.
To fix, run the command below as Administrator in PowerShell and try again:
Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force

大意是解决方法在终端中执行如下命令

Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force

5. 再次执行npm-windows-upgrade

显示内容如下

npm-windows-upgrade v6.0.1
? Which version do you want to install? (Use arrow keys)
> 6.9.0
  6.9.0-next.0
  6.8.0
  6.8.0-next.2
  6.8.0-next.1
  6.8.0-next.0
  6.7.0
(Move up and down to reveal more choices)

6. 再次执行npm-windows-upgrade -p -v latest
