在github-https://GitHub.com/microsoft/typescript/issues/32333上发现相关问题。@rbuckton建议升级
我在我的angular 8应用程序中出现了错误，在尝试了所有的建议之后，包括已接受的答案，我还是无法解决这个问题。我不得不查看以前的一个angular 6应用程序，该应用程序编译时没有出错，我意识到我可以跳过库检查，包括
“SkipLibChecking”:true
到tsconfig.json文件。由于我的应用程序运行良好，没有问题，我决定采取这种方法。下面是tsconfig.json文件的完整配置
{ "compileOnSave": false,
"compilerOptions": {
"baseUrl": "./",
"outDir": "./dist/out-tsc",
"sourceMap": true,
"declaration": false,
"downlevelIteration": true,
"experimentalDecorators": true,
"module": "esnext",
"moduleResolution": "node",
"importHelpers": true,
"target": "es2015",
"typeRoots": [
"node_modules/@types"
],
"lib": [
"es2018",
"dom"
],
"skipLibCheck": true
},
"angularCompilerOptions": {
"fullTemplateTypeCheck": true,
"strictInjectionParameters": true
}
}
此配置后没有更多错误。注意:这并不意味着问题已经解决，但至少它允许我跳过导致错误的bug。由于我的应用程序正在按预期运行，我只是认为这个错误与此无关。
我怀疑是因为你的包含部分:
"include": [
"app/**/*.ts",
"app/**/*.tsx",
"test/**/*.ts",
"test/**/*.tsx",
"node_modules/@types/**/*.d.ts",
"./types/**/*.d.ts"
]
通常不需要显式地包含*.d.ts文件。而且可能从不声明来自其他库（或节点类型）的文件。
默认情况下，
检查tsconfig.json上的Typescript文档，它详细解释了“typeroots”，“files”和“include/exclude”配置选项。
