The file to read its in same folder that js.
要在与 js.txt 相同的文件夹中读取它的文件。
But im don't understand what im doing wrong
但我不明白我做错了什么

fs.readFileSync('moviedata.json', 'utf8')will look for moviedata.jsonin the directory from where you ran your application, not in the directory where your MoviesLoadData.jsfile is located.
fs.readFileSync('moviedata.json', 'utf8')将moviedata.json在您运行应用程序的目录中MoviesLoadData.js查找，而不是在您的文件所在的目录中查找。
Suppose you ran node aws/MoviesLoadData.jsfrom /Users/dortiz/Documents/NodeJS/pruebas/zw, fs.readFileSync('moviedata.json', 'utf8')would look for moviedata.jsonin /Users/dortiz/Documents/NodeJS/pruebas/zw, not in /Users/dortiz/Documents/NodeJS/pruebas/zw/aws
假设你跑node aws/MoviesLoadData.js了/Users/dortiz/Documents/NodeJS/pruebas/zw， fs.readFileSync('moviedata.json', 'utf8')会寻找moviedata.jsonin /Users/dortiz/Documents/NodeJS/pruebas/zw，而不是 in/Users/dortiz/Documents/NodeJS/pruebas/zw/aws
If you were to run your script with my given example, you'd need to prepend the path to the json file to correctly reference it.
如果您要使用我给定的示例运行脚本，则需要在 json 文件的路径之前添加以正确引用它。
fs.readFileSync(__dirname + '/moviedata.json', 'utf8')
I'm not sure how you run your code, so my example may not work in your codebase, but hopefully understanding where you went wrong will help debug your code.
我不确定您如何运行代码，因此我的示例可能无法在您的代码库中运行，但希望了解您出错的地方将有助于调试您的代码。
