Angular cli build prod:TypeError:无法读取未定义的属性“种类" [英] Angular cli build prod: TypeError: Cannot read property 'kind' of undefined

问题描述

我尝试使用 Angular CLI ng build --prod 构建项目，但出现此错误:

I try to build project with Angular CLI ng build --prod and I get this error:

TypeError 中的错误:无法读取未定义的属性种类"

ERROR in TypeError: Cannot read property 'kind' of undefined

如果我不使用 --prod 构建，我不会收到任何错误

if I build with not --prod I do not get any error

完全错误:

ERROR in TypeError: Cannot read property 'kind' of undefined

推荐答案

现在请记住 TypeScript 3.6.4 已发布. 不过，阅读下面的内容并没有真正发挥作用是可以的.

Keep in mind now TypeScript 3.6.4 is out. Still, it's ok to read below what wasn't really working.

TypeScript <=3.6.3 提出了这个问题，处理无父级isParameterPropertyDeclaration 中的节点.

TypeScript <= 3.6.3 presents this issue, Handle parentless nodes in isParameterPropertyDeclaration.

如果您安装 3.7(dev 或新的 beta)，它会编译正常.

If you install 3.7 (dev or the new beta), it will compile fine.

注意:如果您在构建时收到 ERROR，关于 TS 版本，只需通过 tsconfig 禁用它.
为此使用 disableTypeScriptVersionCheck

Note: if you receive an ERROR on building, regarding the TS version, just disable it via tsconfig.
For that use disableTypeScriptVersionCheck

"angularCompilerOptions": {
  "disableTypeScriptVersionCheck": true
},
"compilerOptions": {
 ...
