這是完整的堆棧跟蹤？ '長度'被用在很多模塊中。也許你的一些依賴不正確 –

它是有道理的。它發生後，我運行npm安裝..它完整stacktrace我會更新我的帖子，你可以看到 –

我更新了我的文章 –

您可能會缺少一個或多個打字稿試圖處理的文件。要找出哪個文件丟失，只需添加

console.log（fileName）;

在node_modules/typescript/lib/typescript.js文件的createSourceFile函數的開頭。

我看到該文件在我的節點模塊中，但錯誤仍然存在。 – Milos

您很可能以您需要CLI重啓的方式更改了模塊。

從模塊中刪除組件後，運行ng serve時出現同樣的錯誤。通過重新啓動該過程並重新運行ng serve錯誤消失了。

我的問題是，由於某種原因，我的envioroment.ts文件丟失。所以檢查重要的文件。
