我是nodejs和npm的新手.我正在尝试安装log4js,这是安装的命令:

npm install log4js

我正在从Windows命令行运行它,并且在标记旋转一段时间后,我收到以下错误:

npm ERR! Windows_NT 6.3.9600
npm ERR! argv "C:\\Program Files\\nodejs\\\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "install" "log4js"
npm ERR! node v0.12.0
npm ERR! npm  v2.5.1
npm ERR! code SELF_SIGNED_CERT_IN_CHAIN

npm ERR! self signed certificate in certificate chain

npm ERR! Please include the following file with any support request:

我尝试过npm config set ca=""像这里建议的那样:http://blog.npmjs.org/post/78085451721/npms-self-signed-certificate-is-no-more但我仍然收到此错误.

我该如何解决这个问题并安装NPM？
