\n\n\n可注入 [类 PlatformLocation] 的 JIT 编译失败\nfile:///Users/btaylor/work/angular-apps/dz-outages-ui/node_modules/@angular/core/fesm2015/core.mjs:4058\n抛出新错误(消息);\n^
\n
\n\n错误:可注入的“PlatformLocation”需要使用 JIT 编译器进行编译,但“@angular/compiler”不可用。
\n
\n\n可注入程序是已部分编译的库的一部分。\n但是,Angular 链接器尚未处理该库,因此 JIT 编译用作后备。
\n
\n\n理想情况下,使用 Angular 链接器处理该库以进行完全 AOT 编译。\n或者,应使用 \'@angular/platform-browser-dynamic\' 或 \'@angular/platform-server\ 通过引导加载 JIT 编译器',\也不在引导之前手动为编译器提供 \'import "@angular/compiler";\'。\nat getCompilerFacade (file:///Users/btaylor/work/angular-apps/dz-outages-ui/node_modules /@angular/core/fesm2015/core.mjs:4058:15)\nat 模块。\xc9\xb5\xc9\xb5ngDeclareFactory (文件:///Users/btaylor/work/angular-apps/dz-outages-ui/ node_modules/@angular/core/fesm2015/core.mjs:32999:22)\nat 文件:///Users/btaylor/work/angular-apps/dz-outages-ui/node_modules/@angular/common/fesm2015/common .mjs:90:28\nat ModuleJob.run (节点:internal/modules/esm/module_job:185:25)\nat 异步 Promise.all (索引 0)\nat 异步 ESMLoader.import (节点:internal/modules/esm /loader:281:24)\nat 异步 loadESM (节点:internal/process/esm_loader:88:5)\nat 异步handleMainPromise (节点:internal/modules/run_main:65:12)
