无法安装作曲家休息服务器

Question

我正在尝试在我的 macOS 中安装 composer rest 服务器，但我遇到了错误。如何解决这些错误并安装 composer rest 服务器？

我正在阅读 this 文章并学习如何实施 Composer 区块链网络。当我运行

npm install -g composer-rest-server

我遇到以下错误

我的节点版本9.4.0 npm 版本 5.6.0

是否必须安装 xcode 至运行此代码？请告诉xcode对运行作曲家

的意义

Answer 1

出现此问题是因为 hyperledger composer tools 不支持 node v9.x.x。

所以，你必须使用node v8.x.x。

步骤：

同时安装 Xcode Command Line Tools.
