netcdf在Node.js程序中不起作用

Question

我想通过使用netcdf（https://www.npmjs.com/package/netcdf）库来在Node.js程序中对NetCDF文件进行编码。

现在，一旦我运行一个程序，我会在下面得到一个错误。

C:\app [master +2 ~1 -0 !]> npm start 

> spaceapps@1.0.0 start C:\app 
> node server.js 

C:\app\node_modules\text-encoding\lib\encoding.js:979 
     throw TypeError('Called as a function. Did you forget \'new\'?'); 
    ^

看来库中有错误。 我很感谢有人告诉我一个解决方案。

正如开发人员所说，他有no plans in the short or medium term to continue development，所以你可以考虑使用netcdfjs，它是一个JavaScript库，允许读取NetCDF v3文件。因为它是一个NodeJS包，所以你可以在服务器端运行它，而对于常规大小的文件，你可以在线阅读它，这里有一个example。
