I am trying to use npm's prepare script to run a build step when npm installing from a different project.
The script does run during the npm install however, it doesn't build out the dist folder inside node modules.
Refer to this article for more details http://jim-nielsen.com/blog/2018/installing-and-building-an-npm-package-from-github/
I also had the same problem. My prepare script wasn't creating the build directory in the node_modules folder when installing as dependency.
Finally I found out that my .gitignore was the problem, which was setup to ignore the build directory for version control. NPM is inheriting the .gitignore file when no .npmignore can be found, which was the case here.
As stated on https://docs.npmjs.com/misc/developers:
If there’s no .npmignore file, but there is a .gitignore file, then npm will ignore the stuff matched by the .gitignore file
So I solved the problem by simply adding an empty .npmignore in the root.
I hate to provide such a simple answer, but my solution was to use npm install rather than yarn, which apparently doesn't run the prepare script properly.

Is there a way to restrict npm link to create the symlink only to point at ./dist?
I am struggling so far as I want to test my library (react component) locally before publishing.
In my package.json I have included the main (entry point):
"main": "./dist/index.js"
But still when I run npm link it links to the parent folder which has node_modules and so on.
This is causing problems cause now I have 2 react apps installed.
I thought of a way to exclude node_modules but I couldn't even find a way to do that.
This is actually simpler than expected. First run ng build to build your library project, then go under the dist folder and run npm link from there instead of the library root project. The symlink will be created pointing to the dist folder instead.
Using "main" parameter doesn't make sense because npm link use 'npm prefix' for create symlink
see here
You can use next hack:
Cd to project directory
Copy package.json from package to ./dist/package.json directory
Cd to dist directory
Run 'npm link'
It looks dirty but seem to only way to do it with npm link
can anybody tells me what are those errors about and how to fix them?
Everytime i try to install something in node with npm these errors show up in terminalenter image description here
ENOENT stands for basically "Error, No Entry". this means it was looking for the package.json file and it couldn't find it.The fields mentioned below are also not found because they are a part of the package.json file
so create a package.json file in the current current directory using
npm init
and add the required content in the required fields
i would also recommend you to install the modules locally into the directory of the particular project using
npm install express --save
Hope my answer helps,
cheers
The error you are facing is because you do not have package.json file. Npm installs the package in a node_modules/ subfolder, but warns you that there is no package.json file. If you want to manage localy installed npm packages you should create a package.json file. Start by creating an empty folder:
$ mkdir myapp
$ cd myapp
and then create a new package.json executing
$ npm init
Answer (or skip) all questions and at the end a brand new package.json will be created.
You can get more information from the Getting started articles in npm documentation: Working with package.json
I want to install a local project by using "file:../project-name" in the package.json. However, when I run this command it only installs the dependencies of the local project (node_modules) and not the source files itself.
I have project-name/src for example and I expect it to appear in node_modules/project-name/src, but it doesn't.
I checked the .gitignore (I don't have a .npmignore file) and src as a folder is not excluded.
What am I not seeing here?
If you refer to the files property, this does not indicate files to copy to the node_modules on npm install, but it indicates the files to publish on npm publish.
Edit
When including a dependency with file:... in a project, the directory has to:
have a package.json
Declare exported files in the "files" property.
I am doing a small Sinatra project and I want to use Gulp.
I have node(v0.12.0), npm(2.13.1), gulp(3.9.0) installed. I am in my project directory but when I try install a package like "npm install gulp-sass --save-dev", it doesn't create any "node_modules" folder in my project directory. It seems to be installing the package in my user home directory. Anything I am doing wrong?
From the npm documentation:
Starting at the $PWD, npm will walk up the folder tree checking for a folder that contains either a package.json file, or a node_modules folder. If such a thing is found, then that is treated as the effective "current directory" for the purpose of running npm commands. (This behavior is inspired by and similar to git's .git-folder seeking logic when running git commands in a working dir.)
If no package root is found, then the current folder is used.
I've encountered a weird issue when installing Gulp in a new project.
Let's say I have the following path:
c:/development/myproject
When I run npm install gulp in that directory, the node_modules folder actually gets created in
c:/development/node_modules
instead of
c:/development/myproject/node_modules
And all of gulp plugins also get installed in that directory outside my project root.
I also have an earlier project where gulp was already installed before, and when I tried to rerun gulp installation in that project directory it was installed correctly in the project root (for example: c:/development/myolderproject/node_modules), not outside.
I don't think it has anything to do with the case, but the new project is using Laravel 4, while the other one is on Laravel 5.
I don't recall having to set any specific configuration before, so I'm totally confused why it behaves differently.
When you did npm install it found package.json from parent directory and thought it was the package root.

I run Ubuntu 15 and I had a similar issue where gulp was installing the node_module folder somewhere I couldn't find. gulp would say ../../node_modules was the location but it was NOT in my project folder.
I figured out from the link above and some more research I just needed to run npm init to create a project.json in my project folder. gulp was installing the node_modules in another folder because it searches for a project.json file to install the folder node_modules into.
Hope this helps anyone else solve this silly problem.
