Question

每当我尝试使用npm安装节点包时，它都会运行以下命令：

npm http 304 http://registry.npmjs.org/cryptiles
npm http 200 http://registry.npmjs.org/readable-stream/-/readable-stream-1.1.10.tgz
npm http 200 http://registry.npmjs.org/domhandler/-/domhandler-2.2.0.tgz
npm http 304 http://registry.npmjs.org/delayed-stream/0.0.5
npm http 200 http://registry.npmjs.org/esprima
npm http GET http://registry.npmjs.org/esprima/-/esprima-1.0.4.tgz
npm http 200 http://registry.npmjs.org/esprima/-/esprima-1.0.4.tgz
npm http 200 http://registry.npmjs.org/punycode
npm http GET http://registry.npmjs.org/punycode/-/punycode-1.2.3.tgz
npm http GET http://registry.npmjs.org/core-util-is
npm http GET http://registry.npmjs.org/debuglog/0.0.2
npm http 200 http://registry.npmjs.org/punycode/-/punycode-1.2.3.tgz
npm http 200 http://registry.npmjs.org/core-util-is
npm http GET http://registry.npmjs.org/core-util-is/-/core-util-is-1.0.1.tgz
npm http 200 http://registry.npmjs.org/debuglog/0.0.2
npm http GET http://registry.npmjs.org/debuglog/-/debuglog-0.0.2.tgz
npm http 200 http://registry.npmjs.org/core-util-is/-/core-util-is-1.0.1.tgz
npm http 200 http://registry.npmjs.org/debuglog/-/debuglog-0.0.2.tgz
npm http 200 http://registry.npmjs.org/argparse
npm http GET http://registry.npmjs.org/argparse/-/argparse-0.1.15.tgz
npm http 200 http://registry.npmjs.org/argparse/-/argparse-0.1.15.tgz
npm http GET http://registry.npmjs.org/underscore
npm http GET http://registry.npmjs.org/underscore.string
npm http 304 http://registry.npmjs.org/underscore
...

我知道这些是包的依赖项，但是例如现在安装了cryptiles包，下次当我想安装另一个依赖于cryptiles的包时，npm再次运行此命令：

npm http 304 http://registry.npmjs.org/cryptiles

有什么建议吗？

npm按设计方式工作。

因为npm在本地安装软件包，而不是全局安装软件包，所以最终会有多个版本的cryptiles软件包，因为您的应用程序依赖于0.2.x而另一个软件包依赖于0.1.x

您可以阅读由npm的创建者撰写的this blog post的第一项（同时处理同一事物的多个版本）以更好地理解这一点
