推荐答案

实例化Jav ascript智能合约Fabric会创建一个链码容器，并安装您的Javascript合约（或示例）以及所有npm依赖项。这意味着必须可以访问带有这些模块的npm注册表。

When you instantiate a Javascript Smart Contract the Fabric creates a chaincode container and installs your Javascript contract (or sample) AND all the npm dependencies. This means that an npm registry with those modules must be accessible.

我怀疑您在公司代理/防火墙的后面，或者在没有直接代理的区域工作访问npm。在您的主机上，您可能有一个 .npmrc 文件，该文件可帮助代理，因此您需要将其复制为链码。

I suspect that you are behind a corporate proxy/firewall, or working in a region where there is no direct access to npm. On your host machine you probably have a .npmrc file which helps with the proxy, and you need to replicate that for the chaincode.

我认为，您需要将.npmrc文件放置在Smart Contract项目的根文件夹中，即与package.json文件位于同一文件夹中。

I think you need to place the .npmrc file in the root folder of your Smart Contract project - i.e. in the same folder as the package.json file.
