IBM 区块链平台 Visual Studio Code：打包智能合约时出错

Question

我在 Visual Studio Code 上的 IBM Blockchain Platform 上打包智能合约时遇到了问题。我安装了以下内容：

Node.js v14.16.0 npm 6.14.11 Docker 版本 19.03.13，构建 cd8016b6bc docker-compose 版本 1.25.5，构建未知

我成功创建了一个新的智能合约项目。当我 ram 命令 - 在 Command Pallete 中打包打开项目。 我收到此错误消息：

尝试先运行npm install（甚至可能在之后重新加载 VS Code）。
