angular - 无法解析模块@angular/core 中的错误

Question

在从 webpack2 迁移到 webpack4 以及从 Angular4 迁移到 Angular5 的过程中，我遇到了 webpack 编译的奇怪错误 (./node_modules/.bin/webpack- cli):

ERROR in Could not resolve module @angular/core

调试 webpack (node --inspect-brk ./node_modules/.bin/webpack-cli) 得到一个错误堆栈跟踪:

Error: Could not resolve module @angular/core

但不幸的是它仍然没有给出提示。

这里是 package.json dependancies .

报告此 issue on angular repo 。

我安装模块 @angular-devkit/core 解决了这个问题
