关于 vscode extension Cannot find module 'brace-expansion'

[chenqh]

我写了一个 hello world 的插件，调试模式没有问题
但是我vsce package生成 vsix，用 vscode install 之后，
在 development tools 的 log 里面会有这个问题

extensionService.ts:786 Activating extension '***.helloworld' failed: Cannot find module 'brace-expansion'.

就算我 cnpm install brace-expansion，还是有问题，这个问题怎么解决？
