npm 安装 jointjs时 出现
D:\Project\demo>npm install jointjs npm ERR! code UNABLE_TO_VERIFY_LEAF_SIGNATURE npm ERR! errno UNABLE_TO_VERIFY_LEAF_SIGNATURE npm ERR! request to https://registry.npmjs.org/jointjs failed, reason: unable to verify the first certificate npm ERR!

设置下npm config set strict-ssl false
就行了,一个大坑。
