我正在尝试使用 azure 的工作台和其他资源来启动区块链。我已经安装了所有先决条件，并且在安装区块链服务以创建联盟时没有问题，并且在构建项目时没有问题，我在使用命令构建智能合约时遇到问题 - 'Azure Blockchain: Build Contracts' in vs代码终端，下面是给定的错误。

VS 代码告诉我安装 .NET CLI，我稍后会告诉我如何检查我的项目是否已完全构建。

一个到 github 的链接！

我曾尝试使用 npm 安装软件包，但我也遇到了错误。我不知道是否将 truffle 作为先决条件安装 npm 是否会安装构建 azure solidity 项目所需的所有文件，因为我在安装 truffle 时遇到问题npm

Azure Blockchain: Build Contracts

这是我收到的错误消息。

发生这种情况是因为您缺少一个节点包。我也遇到了同样的问题。

解决方案 -

npm install -g hdwallet-provider

在此重新启动 VS Code 并尝试构建后，它将构建...
