使用gulp编译typescript时，为什么这配置会出错呢

Question

1. 使用gulp 编译 typescript ，

var gulp = require('gulp'),
tslint = require('gulp-tslint')


console.log(tslint)

gulp.task('lint', function () {
  return gulp.src([
    './source/ts/**/**/**.ts',
    './test/**/**.test.ts'
    ]).pipe(tslint())
    .pipe(tslint.report('verbose'))
})

gulp.task('default', ['lint'], function () {
  console.log('242342')
})

执行报错：

Cannot find module 'typescript'

其实我都已经全局安装了typescript 和gulp-typescript 了

Answer 1

本地安装试试

Answer 2

npm 的 ts 包需要加上 --save-dev 的参数。
npm install typescript --save-dev
