我正在使用 Ionic 框架来构建混合应用程序。根据官网，我需要获取 Node.js 的 4.2.4 版本，其中包括 npm 包管理器。 Ionic 所需的依赖项之一是 cordova，因此我运行以下命令来获取它

C:\Users\ferrero>npm install -g cordova

之后，控制台记录

npm info it worked if it ends with ok
npm verb cli [ 'C:\\Program Files\\nodejs\\node.exe',
npm verb cli   'C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js',
npm verb cli   'prefix',
npm verb cli   '-g' ]
npm info using npm@2.14.12
npm info using node@v4.2.4
npm verb exit [ 0, true ]
npm info ok
npm info it worked if it ends with ok
npm verb cli [ 'C:\\Program Files\\nodejs\\node.exe',
npm verb cli   'C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-  cli.js',
npm verb cli   'install',
npm verb cli   'cordova' ]
npm info using npm@2.14.12
npm info using node@v4.2.4
npm verb config Skipping project config: C:\Users\ferrero/.npmrc.
(matches userconfig)
npm verb install initial load of C:\Users\ferrero\package.json
npm verb readDependencies loading dependencies from C:\Users\ferrero\package.json
npm verb cache add spec cordova
npm verb addNamed "latest" is being treated as a dist-tag for cordova
npm info addNameTag [ 'cordova', 'latest' ]
npm verb addNameTag registry:https://registry.npmjs.org/cordova not in flight; fetching
npm verb request uri https://registry.npmjs.org/cordova
npm verb request no auth needed
npm info attempt registry request try #1 at 16:47:06
npm verb request id 62f85abc5c5b7cd5
npm verb etag "6KQ69KRX02Y8MUJFT56H9DE6N"
npm http request GET https://registry.npmjs.org/cordova
npm info retry will retry, error on last attempt: Error: self signed certificate in certificate chain

从日志中可以看到，npm 运行版本 2.14.12，它提示原因是自签名证书 - 可能由 https://registry.npmjs.org/cordova 颁发.所以，为了克服这个问题，我跑了

npm config set registry=http://registry.npmjs.org

然后，之后(只是相关部分)

C:\Users\ferrero>npm install -g cordova

npm verb cache add spec cordova
npm verb addNamed "latest" is being treated as a dist-tag for cordova
npm info addNameTag [ 'cordova', 'latest' ]
npm verb addNameTag registry:http://registry.npmjs.org/cordova not in flight; fetching
npm verb request uri http://registry.npmjs.org/cordova

    npm verb headers   'x-timer': 'S1453834774.362657,VS0,VE1',
    npm verb headers   vary: 'Accept' 
}
npm verb etag http://registry.npmjs.org/cordova from cache
npm verb get saving cordova to C:\Users\ferrero\AppData\Roaming\npm-cache\registry.npmjs.org\cordova\.cache.json
npm verb addNamed "5.4.1" is a plain semver version for cordova
npm verb addRemoteTarball http://registry.npmjs.org/cordova/-/cordova-5.4.1.tgz

npm verb addRemoteTarball [ 'http://registry.npmjs.org/cordova/-/cordova-5.4.1.tgz',
npm verb addRemoteTarball   'bc56bc1d3c5387a7926408212dfbce59002f9d76' ]

这一次，它没有提示其他任何事情。相反，加载指示器 - 一个管道字符 - 继续运行。那么，我应该怎么做才能下载这样的依赖呢？

最佳答案

我们似乎在这里关注两个不同的问题。

证书错误可能是由于出站 SSL 代理。某个人，很可能是您的雇主，正在关闭所有 SSL 流量。要修复它，您需要通过导入正在使用的代理的 CA 证书来告诉 NPM 这个证书是可以的。

npm config set cafile = "/the/certificate/file.pem"

您可能还需要为 npm 设置代理地址:

npm config set proxy http://proxy.example.com:3128
npm config set https-proxy http://proxy.example.com:3128

根据我的研究，似乎已经修复了与 Node 5.0 的不兼容问题。文档似乎已经过时了。

Cordova 中的错误可能是 missing method in the Q promises library ，Cordova 所依赖的。

2015 年 11 月，用户能够 use Ionic successfully with node 5.1.0 .
