Question

我开发了一个带有jhipster的应用程序并试图将我的应用程序切换到生产版本，它在使用错误代码的纱线安装命令时失败：

 Error: Error encountered resolving symbol values statically.

@ angular / material / typings / index.d.ts是一个非常简单的打字稿文件，没有什么特别之处。

/**
 * Generated bundle index. Do not edit.
 */
export * from './public_api';
export { mixinColor as ɵu } from './core/common-behaviors/color';
export { mixinDisabled as ɵv } from './core/common-behaviors/disabled';
export { UNIQUE_SELECTION_DISPATCHER_PROVIDER_FACTORY as ɵh } from './core/coordination/unique-selection-dispatcher';
export { MdDateFormats as ɵw } from './core/datetime/date-formats';
export { OVERLAY_CONTAINER_PROVIDER as ɵb, OVERLAY_CONTAINER_PROVIDER_FACTORY as ɵa } from './core/overlay/overlay-container';
export { OverlayPositionBuilder as ɵt } from './core/overlay/position/overlay-position-builder';
export { VIEWPORT_RULER_PROVIDER as ɵd, VIEWPORT_RULER_PROVIDER_FACTORY as ɵc } from './core/overlay/position/viewport-ruler';
export { SCROLL_DISPATCHER_PROVIDER as ɵf, SCROLL_DISPATCHER_PROVIDER_FACTORY as ɵe } from './core/overlay/scroll/scroll-dispatcher';
export { RippleRenderer as ɵg } from './core/ripple/ripple-renderer';
export { EXPANSION_PANEL_ANIMATION_TIMING as ɵi } from './expansion/expansion-panel';
export { MdGridAvatarCssMatStyler as ɵk, MdGridTileFooterCssMatStyler as ɵm, MdGridTileHeaderCssMatStyler as ɵl, MdGridTileText as ɵj } from './grid-list/grid-tile';
export { MdMenuItemBase as ɵn, _MdMenuItemMixinBase as ɵo } from './menu/menu-item';
export { MdPaginatorIntl as ɵx } from './paginator/paginator-intl';
export { MdTabBase as ɵr, _MdTabMixinBase as ɵs } from './tabs/tab';
export { MdTabLabelWrapperBase as ɵp, _MdTabLabelWrapperMixinBase as ɵq } from './tabs/tab-label-wrapper';

我真的不知道这个问题的解决方案是什么，可能会将@ angular / material降级到某些早期版本，但后来降级到哪一个？
