npm - ubuntun 中的 npm 纱线安装失败

Question

我尝试在 ubuntun 中安装纱线但失败：

$ npm install -g yarn
npm ERR! code UNABLE_TO_GET_ISSUER_CERT_LOCALLY
npm ERR! errno UNABLE_TO_GET_ISSUER_CERT_LOCALLY
npm ERR! request to https://registry.npmjs.org/yarn failed, reason: unable to get local issuer certificate

我该如何解决这个问题！
