Node.js 要求本地文件抛出错误

Question

This is my project's filesystem.

root
index.js
package.json
...etc
commamds
- ping.js
- eval.js
- ...etc

This is a normal discord.js bot. But when I try reloading the commands, I use the following code:

...etc
let pull = require(`./${file}`);
// file is command files from fs.readdirSync() and it can be 'ping.js', 'eval.js', ...
...etc

But it throws a referenceerror that the module can't be found. But when I try fs.readFile(), it works. What's the problem?

Answer 1

fs.readFile() defaults to the current working directory if there is no path or if there's a relative path on the filename.

require() has a completely separate set of rules for where it looks for files. For example, a filename with no path at all looks in the node_modules directory and in the global module location(s). A filename starting with ./ looks in the current module's home directory. And so on... It's a different set of rules than fs.readFile() .

Since you don't show us what file actually is, it's hard to know precisely, but perhaps you need to combine the filename with the appropriate path so you are giving require() a full path name and it will go exactly there, not use the normal rules for where require() looks when given only a plain filename.
