我听说 node-pre-gyp 版本存在问题，因为这个 openalpr 包已经 5 岁了。我该如何克服这个问题？

【解决方案1】：

我在 node-openaplr package.json 中注意到 node-pre-gyp 的依赖项指向 node-pre-gyp 存储库，这意味着它将引入最新版本的 node-pre-gyp，这远远领先于node-openaplr 存储库中的最后一次提交。

fork node-openaplr 存储库并在 package.json 中的 node-pre-gyp 依赖项上指定提交哈希，然后将 node-openaplr 安装到项目使用

yarn add https://github.com/bameyrick/node-openalpr
