下午给新电脑安装node, 第一次测试node，npm都可以用。然后就安装notepad++，vscode，python2.7。之后想着把npm全局路径给改了，执行npm config set prefix “G:\node”，没有问题。然后执行npm config get prefix 就报错,错误如下： FATAL ERROR: MarkCompactCollector: semi-space copy, fallback in old gen Allocation failed - JavaScript heap out of memory

然后测试其它命令，都有这个错误，比如之后卸载重新安装测试npm均有这个问题，换了其它版本安装还是如此，求教如何解决
