我正在local Hyperledger Composer dev environment上为MacBook Pro (MacOS 10.13.2)安装NPM，并在npm install -g composer-cli的输出中显示弃用/包名称更改消息。要进行安装，我按照此位置的说明进行操作：
https://hyperledger.github.io/composer/installing/development-tools.html
我的问题是我是否需要根据这些消息采取行动（见下文），还是我可以继续？请原谅这个基本问题，但在Mac上的这个工作水平上我是一个新手 - 我正在Coursera.org上为Hyperledger课程做这件事。
这是我运行的命令：npm WARN deprecated fs-promise@1.0.0: Use mz or fs-extra^3.0 with Promise Support
npm WARN deprecated crypto@0.0.3: This package is no longer supported. It's now a built-in Node module. If you've depended on crypto, you should switch to the one that's built-in.
npm WARN deprecated jade@1.11.0: Jade has been renamed to pug, please install the latest version of pug instead of jade
npm WARN deprecated transformers@2.1.0: Deprecated, use jstransformer
npm WARN deprecated nodemailer@2.7.2: All versions below 4.0.1 of Nodemailer are deprecated. See https://nodemailer.com/status/
......以下是输出的前几行：
gyp WARN download NVM_NODEJS_ORG_MIRROR is deprecated and will be removed in node-gyp v4, please use NODEJS_ORG_MIRROR
npm install -g composer-playground继续关注Joe Clay的回复，现在只需运行此命令：npm WARN ngx-clipboard@8.0.4 requires a peer of @angular/core@>=4.0.0 but none is installed. You must install peer dependencies yourself.

...并在NPM输出结束时收到以下警告：
Class Student现在将继续，看看这些警告是否会影响最终的开发环境。对于向学生提供类似代码的IBM人群有点失望:(
非常感谢您的帮助！
欢呼，劳伦斯答案 0 :(得分：0)
赞同Joe Clay的回应，你可以忽略他所阐述的那些信息。 peerDependencies在package.json中定义（指Playground所依赖的Angular消息）。
