Debian 9 上的 Vue.js 安裝問題

我正在嘗試在我的 Debian 9 作業系統上安裝 Vue.js，但收到此錯誤消息：非法指令] - rollbackFailedOptional: verb npm-session 1fd93108cdc88b2

當我執行此命令時： npm install vue

npm 的版本是 6.13.7

我遇到了sudo apt-get update問題，這會導致以下錯誤：

Ign:25 http://ppa.launchpad.net/ondrej/php/ubuntu focal/main DEP-11 64x64 Icons

我在 StackExchange 和網路上搜尋了這個錯誤，並嘗試了相關的解決方案（沒有成功）

更改目錄，/etc/apt/sources.list.d然後刪除 Ondrej 和 Barckets PPA，同時刪除php版本和 barckets（軟體包屬於 Ubuntu Bionic 和 Focal）。

要安裝 Barckets，請從此處下載 deb 文件：

sudo apt install gdebi
wget https://github.com/adobe/brackets/releases/download/release-1.14.1/Brackets.Release.1.14.1.64-bit.deb
sudo gdebi Brackets.Release.1.14.1.64-bit.deb

要添加 ondrej 儲存庫，請使用：

sudo apt install apt-transport-https lsb-release ca-certificates curl
sudo wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg
printf "deb https://packages.sury.org/php/ $(lsb_release -sc) main" |sudo tee  /etc/apt/sources.list.d/php.list
sudo apt update

vue並vue-cli安裝：

npm install -g npm
npm install -g vue
npm install -g @vue/cli
