NPM如何运行不在路径中的命令

Question

The ava command is not in my path. I can not run it from in the project directory that contains some AVA tests.

My npm test command of my project is set to ava tests/*.js --verbose , and can somehow call the ava command from the same location in the terminal.

My questions is: how is npm calling the ava command? I suspect it is calling it from the project's node_modules folder, but I could not find it in any source.

If anyone can explain how this happens, or better yet show me the source, I would really appreciate it.

当您运行npm run [script]或本例中的npm test ，NPM非常聪明，可以尝试首先从node_modules/.bin目录执行二进制文件。
