webpack非法指令

Question

我的环境：

• win7-64
• node -v：v4.4.7
• npm -v：v3.10.3

安装webpack后，运行webpack -v会出现此错误

/c/Users/Administrator/.npm-global/webpack: line 14:  9612 Illegal instruction  node "$basedir/node_modules/.webpack_npminstall/webpa                                                                                                                            ck/1.13.1/webpack/bin/webpack.js" "$@"

我尝试运行npm uninstall -g webpack并删除node_modules\.webpack_npminstall文件夹，然后再次安装npm i -g webpack，它仍然失败。有没有人有想法？
