我尝试将Phaser与Brunch一起使用,而TypeScript则使用samme
的brunch-phaser2
框架,但我遇到了TypeError
$ git clone https://github.com/samme/brunch-phaser2.git --branch typescript
$ cd brunch-phaser2
$ npm install
$ npm run start
> a-phaser-game@0.0.1 start /home/sam/github/samme/brunch-phaser2
> brunch watch --server
13:49:11 - info: application started on http://localhost:3333/
13:49:12 - error: Compiling of app/initialize.ts failed. TypeError: Cannot read property 'length' of undefined
Stack trace was suppressed. Run with `LOGGY_STACKS=1` to see the trace.
13:49:12 - info: compiled 5 files into 2 files, copied 3 in 1.5 sec
当我将显式类型添加到我的game
变量中时,my Phaser experimention repo中会出现一个略有不同的TypeError
:
$ git clone https://github.com/samestep/phaser-nonsense.git --branch type-error
$ cd phaser-nonsense
$ npm install
$ npm run start
> @ start /home/sam/github/samestep/phaser-nonsense
> brunch watch --server
13:56:42 - info: application started on http://localhost:3333/
13:56:42 - error: Compiling of app/initialize.ts failed. Error: Error 2503: Cannot find namespace 'Phaser'. (Line: 3, Col: 13)
Stack trace was suppressed. Run with `LOGGY_STACKS=1` to see the trace.
13:56:42 - info: compiled 2 files into vendor.js, copied index.html in 1.3 sec
但不管是哪种情况,当我改变这一点时:
const game: Phaser.Game = new Phaser.Game({});
要这样做:
const game = new Phaser.Game({});
TypeError
消失了。
为什么此显式类型声明会导致 TypeError
错误发生,以及如何在不删除显式类型声明的情况下解决此错误?

Brunch TypeScript插件不支持正确的引用解析(documentation)。他们的建议是将plugins: { brunchTypescript: { ignoreErrors: true } }
添加到您的brunch-config.js
中,并单独运行tsc --noEmit -p .
来检查错误。
