Question

将Typescript版本从2.8.4升级到2.9.2时出现了这个奇怪的错误：

ERROR in ./js/main.ts
Module build failed (from ./node_modules/ts-loader/index.js):
Error: Debug Failure. False expression.

这是我的tsconfig.json：

{
  "compilerOptions": {
  "sourceMap": true,
  "noImplicitAny": true,
  "module": "es6",
  "target": "es6",
  "lib": [
    "es2017",
    "dom"
   ],   
  "allowJs": true,
  "allowSyntheticDefaultImports" : true,
  "experimentalDecorators": true
  }
}

问题：如何获得合适的错误消息以及我做错了什么？而且，我也看到this问题，但我对解决方案和解释不满意 - 我需要使用至少相同的目标，不要将其回滚到'es3'，这是默认值。< / p>

一个web search找到TypeScript bug 24111，它在TypeScript 3.0.1中已修复。尝试升级TypeScript。如果问题仍然存在，请按照以下步骤提交新的TypeScript错误。

Answer 2

尝试在与项目相同的目录中执行“ npm i typescript”。

typescript，错误：forEachIdentifierInEntityName，typescript.js中的“Debug Failure.False Expression”：24094：26
