TypeError:不能读取未定义的属性'flags'

After cloning a repo, npm install && ionic cordova build android --prod shows me following error.

在克隆了一个repo之后，npm install && ionic cordova构建了android——prod显示了以下错误。

TypeError: Cannot read property 'flags' of undefined at checkUnreachable (F:\Works\Projects\ionic-bokfinder\node_modules\typescript\lib\typescript.js:24905:31) at bindChildrenWorker (F:\Works\Projects\ionic-bokfinder\node_modules\typescript\lib\typescript.js:23111:17) at bindChildren (F:\Works\Projects\ionic-bokfinder\node_modules\typescript\lib\typescript.js:23055:17) at bind (F:\Works\Projects\ionic-bokfinder\node_modules\typescript\lib\typescript.js:24319:21) at bindSourceFile

在bindChildrenWorker (F:\Works\ ionic-bokfinder\node_modules)上，无法读取checkun的“标志”

I am sure it worked well without any problems before. Here are my system information and package.json.

我相信它以前运行得很好，没有任何问题。这是我的系统信息和package.json。

Removing @angular/cli should work for you

删除@ angle /cli应该对您有效

if not, change Typescript version to ~2.6.2.

如果没有，请将打字稿版本更改为~2.6.2。

@angular/cli 1.7.3 works with Typescript ~2.6.2 only.

@ /cli 1.7.3只适用于Typescript ~2.6.2。
