WebPACKのコンパイルは私のリアクトアプリを構築しようとすると、ヌル

Question

のプロパティ「セマフォ」を読み込めませんし、私はこのコンパイル・エラーが生じています：

/Users/jimvercoelen/Documents/bitbucket/inboundmuse-client/node_modules/webpack/lib/Compilation.js:268 
               _this.semaphore.release();

そして、私はこの問題を引き起こしているもの見当もつかない。

Answer 1

node_modules/webpack/lib/Compilation.js：268に潜入し、実際にエラーがログに記録された後、完全に使用されるようになりました。それは自分自身のせいでコンパイルできなかったことが起こった。

同じ問題が発生している場合は、そのCompilation.jsからエラーをログに記録してみてください：268ファイル。

if(err) { 
    console.log({ err }) 
    return errorOrWarningAndCallback(new ModuleNotFoundError(module, err, dependencies)); 
}
