hyperledger fabric JavaScript-应用程序节点 app.js 不工作

Question

我是区块链领域的新手，我尝试运行来自 Hyperledger 网络的示例网络遵循 this 文档。我开始下载先决条件并做好所有事情。

网络正在工作并使用 JavaScript 部署它，在所有通道和部署之后我将 cd 放入 JavaScript-应用程序到运行 app.js 作为文档说但是我得到了这个错误

node app
node:internal/modules/cjs/loader:944
  throw err;
  ^

Error: Cannot find module 'pkcs11js'

  ]
}

我不知道错误是从哪里来的节点似乎很好，我可以在 node_modules 和 package-lock.json

中看到所有包

node -v
v16.3.0
npm -v
7.17.0

Answer 1

看起来 fabric node-sdk 已经破坏了 C 编译器是可选的功能，现在它是强制性的，但是因为 pkcs11 仍然被声明为可选的，node-sdk 不会安装失败但会失败运行如你所见。你要么必须

安装 Microsoft C 编译器 + python v3 并重新安装（或重建）fabric node-sdk 节点模块，然后可以构建 pkcs11 本机库（参见 https://www.npmjs.com/package/windows-build-tools关于如何安装编译器和 python)
指定一个特定版本的结构节点 sdk（看起来它在 2.2.4 中被破坏所以 2.2.3 应该可以工作）所以擦除 node_modules 目录并更新 package.json 以指定完全是 fabric-network 的版本（即输入 2.2.3，没有前面的字符，例如 ^ 或 ~）和运行 npm install again
使用 linux 桌面发行版而不是 windows，因为它们往往包含构建本机节点库所需的先决条件

最后要注意的是，您使用的是不受支持的节点和 npm 版本。您应该使用节点 12 或节点 14，因为这些是支持的 lts 版本
