Find npm in wrong place

Related the document, plugin have to find npm on global scope, but it is not.

Caused by: org.gradle.process.internal.ExecException: A problem occurred starting process 'command 'npm''
at org.gradle.process.internal.DefaultExecHandle.execExceptionFor(DefaultExecHandle.java:241)

...
Caused by: java.io.IOException: Cannot run program "npm" (in directory "~/projects/projectRoot"): error=2, No such file or directory

So, I tried to override npm or node excitable path but no effect

My environment is like below.

os.arch = aarch64
os.name = Mac OS X
os.version = 11.2.2
openjdk version "11.0.10" 2021-01-19 LTS
OpenJDK Runtime Environment Zulu11.45+27-CA (build 11.0.10+9-LTS)
OpenJDK 64-Bit Server VM Zulu11.45+27-CA (build 11.0.10+9-LTS, mixed mode)

node -v
v15.10.0
process.arch: arm64

Start with docs/usage.md and its plugin configuration section, then trace how the plugin locates and launches the npm command. Reproduce the reported failure on the stated macOS ARM environment and compare it with the attempted node or npm executable overrides. Done means the configured or globally installed npm executable can be launched successfully.
