Angular 9警告typescript.js

Question

启动应用程序后，出现警告

WARNING in ./node_modules/typescript/lib/typescript.js 5123:41-60
Critical dependency: the request of a dependency is an expression

Answer 1

尝试更改webpack.dev.config.js。

new webpack.ContextReplacementPlugin(
            /angular(\\|\/)core(\\|\/)(esm(\\|\/)src|src)(\\|\/)linker/,
            path.resolve(__dirname, 'doesnotexist/')
)

或者至少，

new webpack.ContextReplacementPlugin( /(.+)?angular(\\|\/)core(.+)?/, root('./src'), {} )
