When running npm test, which is defined by:
"test": "mocha test/**/*.spec.js"
The path expansion fails to match scripts at a depth of more than one. Therefore everything in test/lib/*.spec.js gets matched, but a test at test/lib/subdir/*.spec.js does not.
When I run mocha test/**/*.spec.js, however, all the tests are matched and run. I'm at something of a loss as to how to debug this.
EDIT
I'm pretty sure this is due to npm running scripts in sh instead of my shell (zsh). I don't know how to fix this.

In my npm project, in my package.json file, I have the following lines of code:
"scripts": {
"build": "webpack"
},
While in my terminal, if I run npm webpack, I get the error message:
Unknown command: "webpack"
But if I run npm run build, I get a prompt from webpack saying I need webpack-cli... so the command is obviously recognized.
I'm confused about the different behavior of these two commands. In this case, isn't running npm run build identical to running npm webpack in my terminal? Why does one command fail and one succeed? What is actually happening when I run npm run build?
If we look at the documentation,
Environment
Package scripts run in an environment where many pieces of information are made available regarding the setup of npm and the current state of the process.
path
If you depend on modules that define executable scripts, like test suites, then those executables will be added to the PATH for executing the scripts.
Maybe this is the reason webpack is not recognized by the command line.
I have a monorepo with several workspaces within it. It has been very common for me to use chained npm scripts for simple tasks instead of using a task runner. So for example, the following configuration (pseudo code) is very common for me and usefull as well, specially for pre and post build scripts
"scripts": {
"prebuild:task1":"task1 --task1-arguments",
"prebuild:task2":"task2 --task2-arguments",
"prebuild": "npm run prebuild:task1 && npm run prebuild:task2",
"build":"build-script --build-arguments",
}
So the above is the package.json for the child worskpace itself and then in the master package.json I have the call to the script that triggers the build for that workspace.
build:packageA: "npm run build -w packageA"
All seems working well but the chained "npm run script" inside the workspace is actually execute in the context of the master monorepo and not inside that particular workspace.
So, in summary, the first call is to run the build script in the workscape and then triggers the prebuild script of that workspace BUT as that script execute chained npm run scripts those are run in the context of the master repo which happens that they don't exist in there. So the callstack might be ...
(master) build:packageA
(packageA) prebuild
(master) npm run prebuild:task1 >>>> EXIT ERROR
The only way I found, up to now, to bypass this issue was to make my child workspace a monorepo itself holding zero woskpaces. Essentially I have a "workspaces" key in its package.json pointing to the root directory. This enables me to use the -w flag in the scripts section so to refer all scripts to itself. So my current workaround looks like this ...
"workspaces": ["."],
"scripts": {
"prebuild:task1":"task1 --task1-arguments",
"prebuild:task2":"task2 --task2-arguments",
"prebuild": "npm run prebuild:task1 -w packageA && npm run prebuild:task2 -w packageA",
"build":"build-script --build-arguments -w packageA"
}
Isn't there already a better way to solve this?
Thanks in advance to everyone!
Following this post https://stackoverflow.com/a/67060676 I found out that npm changed the way it calls nested scripts in workspaces.
I ran into similar issues like you while running npm#7.5, but the feature was introduced in npm#7.7. Updating node to v17 and npm to 8.3 resulted in everything is running as intended.
In my case I wanted to execute nested npm run build commands in workspaces.
I have tests setup for a package I maintain - create-new-app. When I run npm publish, I want the tests to run first and only if they pass, move on to the publish portion. I thought this is what prepublishOnly was for. My prepublishOnly value looks like this:
prepublishOnly: "npm run test"
That successfully runs the tests prior to publishing, but if the tests fail, it still publishes! How can I get the publish to happen only when tests pass?
it's possible that your npm run test command is not returning a proper error code of non-zero
Every time I run npm run dev(that's how my team set up that project) I get this error:
ERROR EEXIST: file already exists, mkdir 'X:......\my-project\.nuxt'
I then need to do mkdir .nuxt and try again. Usually it works, sometimes it doesn't: it keeps asking me that everytime I run npm run dev and after 5 or 10 times it works. Sometimes I won't work no matter how many times I try, so I restart my machine and then it works.
Any idea what's going on?
I have had issues of this kind when running in the past with gulp in parallel tasks that would delete and write to the same deleted directory. But, without having more information about this, and just knowing that sometimes the .nuxt directory is missing. I can't really get to the root of the problem. It might be something related with the nuxt.config.js
This is the only solution that I see for now.
Even though this might not fix the original issue what you could do to at least be able to develop without having to worry any longer is:
Add the rimraf package and run it always before running the dev command.
Add the mkdirp package and run it after the deletion of the folder happen
If you add the commands globally now you should have in your terminal both commands available and you can run
rimraf ./.nuxt && mkdirp .nuxt && npm run dev
This would be the least intrusive approach as it wouldn't affect any of your team members.
If also they are affected by this you can also add this packages as a devDependency and add another npm run dev command as shown here.
{
...
"scripts": {
"dev": "rimraf ./.nuxt && mkdirp .nuxt && npm run dev"
}
...
}
I have created a Scala, Play project. I am trying to add Angular2 in it. I added two npm commands through edit configuration. They are suppose to install the required packages and use webpack to bundle final JS. I notice that nothing happens after 2nd script is executed (I do not know if that script is hung or there is some other issue (see pic). It seems that the 2nd npm script is stuck because on stopping the run command, I see exit code 1 - Process finished with exit code 1
Is there a way to find out if Intelli build/run process is still running?
The issue was with the 2nd script (npm start). I had to remove --profile --watch flag from the webpack command. This works - "scripts": {
"start": "webpack --config webpack.config.dev.js --progress"
}
