无法启动 Clinic.js，我该怎么办？

Question

At startup: clinic doctor --on-port 'autocannon -m POST localhost:8000/users/register' -- node dist/main.js

Gives help log: Clinic.js Doctor - v9.2.0

clinic doctor is the first step in profiling your application. It will show you what kind of problem you are having and recommend the path forward.

To run clinic doctor

clinic doctor -- node server.js

Once you exit (Ctrl-C) the process, your report will open in a browser window. You can disable this behavior:

clinic doctor --open=false -- node server.js

If profiling on a server, it can be useful to only do data collection:

clinic doctor --collect-only -- node server.js

You can then transfer the data and visualize it locally:

clinic doctor --visualize-only PID.clinic-doctor-sample

You can use the --autocannon flag to simulate load on your server. --autocannon accepts configuration for autocannon using "subarg" syntax:

clinic doctor --autocannon [ -m POST /api/example ] -- node server.js

When configuring --autocannon, the $PORT environment variable contains the port your server is listening on:

clinic doctor --autocannon [ -m POST 'http://localhost:$PORT/?\$page=1' ] -- node server.js

Note that dollar signs ($) appearing in the URL must be escaped, else they will be treated as environment variables as well.

Flags -h | --help Display Help -v | --version Display Version --collect-only Do not process data on termination --visualize-only datapath Build or rebuild visualization from data --sample-interval interval Sample interval in milliseconds --on-port Run a script when the server starts listening on a port. --autocannon Run the autocannon benchmarking tool when the server starts listening on a port. --open Boolean to enable or disable your report opening in your web browser. --dest Destination for the collected data (default.clinic/).

If you're using Powershell to run it, it will not work. I don't know why exactly but I had the same issue. it's working fine with CMD.
