類型錯誤：this.getOptions 不是函數 - TypeError: this.getOptions is not a function

問題：

I am facing a weird error when I installed Bootstrap .我在安裝Bootstrap時遇到了一個奇怪的錯誤。 The error is below.錯誤如下。 I tried uninstalling less-loader and installing [email protected], because I saw it online, but it did nothing.我嘗試卸載less-loader並安裝[email protected]，因爲我在網上看到它，但它沒有任何作用。 I am unsure what to do at this step.我不確定在這一步要做什麼。

Syntax Error: TypeError: this.getOptions is not a function語法錯誤：TypeError：this.getOptions 不是函數
