我一直在尝试在我的 package.json 文件上运行 npm install，但我遇到了很多麻烦。它一直在说“错误：尝试解锁尚未锁定的
XXX”。这是其中之一：

Error: Attempt to unlock tbd@~0.6.4, which hasn't been locked
        at unlock (/usr/local/lib/node_modules/npm/lib/cache.js:1304:11)
        at cb (/usr/local/lib/node_modules/npm/lib/cache.js:646:5)

        at Object.oncomplete (fs.js:107:15)

如果我尝试将它作为 sudo 运行，它似乎会更进一步并开始安装一些软件包，但会弹出一些新错误：

我最近更新了我的节点和 npm 安装。所以也许这与它有关。此外，我的大部分开发工作都是在办公室进行的，而今天我正在通过 VPN 工作，所以也许这也与它有关。

有任何想法吗？
