我正在尝试导入这样的模块：
const speech = require('@google-cloud/speech');
当我运行“ npm run watch”时，出现了很多这样的错误：
ERROR in ./node_modules/@grpc/grpc-js/build/src/channel-credentials.js
Module not found: Error: Can't resolve 'tls' in ...
ERROR in ./node_modules/forever-agent/index.js
Module not found: Error: Can't resolve 'tls' in ...
ERROR in ./node_modules/tunnel-agent/index.js
Module not found: Error: Can't resolve 'tls' in ...
似乎我无法解决某些依赖关系，但不确定如何解决此问题。
我跑了
~/learn-node $ node
> module.paths
检查包含@ google-cloud / speech的文件夹是否在所搜索的路径之一中。
