vscode扩展初体验之一：安装Yeoman

似乎是从chrome开始，插件不叫插件了，改名叫扩展。vscode也不例外。今天尝试写一个vscode的插件，好吧，是扩展。
按照官网(github上有一个翻译项目CN-VScode-Docs还没翻完，有兴趣可以一起翻)的指导，第一步要先通过npm安装Yeoman。如下所示：

$ npm install -g yo generator -code
npm WARN deprecated nomnom@1.6.2: Package no longer supported. Contact support@npmjs.com for more info.
npm WARN deprecated minimatch@0.2.14: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue
npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules
npm ERR! path /usr/local/lib/node_modules
npm ERR! code EACCES
npm ERR! errno -13
npm ERR! syscall access
npm ERR! Error: EACCES: permission denied, access '/usr/local/lib/node_modules'
npm ERR!  { Error: EACCES: permission denied, access '/usr/local/lib/node_modules'
npm ERR!   stack: 'Error: EACCES: permission denied, access \'/usr/local/lib/node_modules\'',
npm ERR!   errno: -13,
npm ERR!   code: 'EACCES',
npm ERR!   syscall: 'access',
npm ERR!   path: '/usr/local/lib/node_modules' }
npm ERR!

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/xxx/.npm/_logs/2018-09-09T14_40_04_435Z-debug.log

还得先更新npm

$ npm i -g npm
npm ERR! path /usr/local/lib/node_modules/npm/node_modules/abbrev
npm ERR! code EACCES
npm ERR! errno -13
npm ERR! syscall access
npm ERR! Error: EACCES: permission denied, access '/usr/local/lib/node_modules/npm/node_modules/abbrev'
npm ERR!  { Error: EACCES: permission denied, access '/usr/local/lib/node_modules/npm/node_modules/abbrev'
npm ERR!   stack: 'Error: EACCES: permission denied, access \'/usr/local/lib/node_modules/npm/node_modules/abbrev\'',
npm ERR!   errno: -13,
npm ERR!   code: 'EACCES',
npm ERR!   syscall: 'access',
npm ERR!   path: '/usr/local/lib/node_modules/npm/node_modules/abbrev' }
npm ERR!
npm ERR! Please try running this command again as root/Administrator.

又失败了，提示权限不够，打开不了/usr/local/lib/node_modules/npm/node_modules/abbrev。于是，用sudo来执行

$ sudo npm i -g npm

/usr/local/bin/npx -> /usr/local/lib/node_modules/npm/bin/npx-cli.js

+ npm@6.4.1
added 283 packages, removed 306 packages and updated 41 packages in 35.995s

再次安装Yeoman，又失败，提示usr/local/lib/node_modules又没权限。于是，又用sudo搞定

$ sudo npm install -g yo generator -code

Running sanity checks on your system

✔ Global configuration file is valid
✔ NODE_PATH matches the npm root
✔ Node.js version
✔ No .bowerrc file in home directory
✔ No .yo-rc.json file in home directory
✔ npm version
✔ yo version

Everything looks all right!
+ yo@2.0.5
+ generator@1.0.1
added 572 packages from 279 contributors in 72.323s

顺便说下，上面的命令写错了，generator -code中间不能有空格。。。
正确的命令如下所示：

$ sudo npm install -g yo generator-code

搞定后，第二步是生成扩展的框架代码，跟官网的例子不同的是，我选择的是js，而不是ts。

$ yo code
