I have a simple question that i cant seem to find the answer for. I cloned a git repo to my local machine.
When attempting to start node, I receive an error because i don't have the required npm dependencies installed. However, they are located in the packages.json file that was cloned.
I was wondering if there was a simple way to install the dependencies located in that file, without having to npm install for every individual package.
Within the directory of the package.json file, just run npm install. It will read package.json and install all dependencies. If you want to limit it to only non-dev dependencies, use npm install --only=production.

There's a public tool (csso-cli) that can be installed with npm install -g csso-cli to be available globally. Now I need to make a modification to it and change one of its dependencies (csso) to a newer version to use the latest features. So I cloned the repository and installed that with npm install -g ./. It did copy that local code directory to my global npm installation location, but none of the required dependencies were added. There simply isn't a node_modules subdirectory in the install location.
How can I properly install an npm package from a local directory, including all external dependencies, as if it were installed from a public repository? Maybe I need to create some sort of package file first and install that? I don't know much about npm. I searched the web but couldn't find anything. (All instructions are missing the dependencies.) I've read the npm documentation but am still no wiser. That topic isn't covered here, still only incomplete installations without dependencies seem possible. Who needs that?
Looks like I needed the npm pack command. It creates an archive of the package from the local directory. When installing that file with npm install -g my-package-1.0.0.tgz all dependencies are properly installed as well. Plus, the package file doesn't contain the git files.
I would like to clone https://github.com/tstringer/create-react-app-with-redux and start a new project. I ran npm start and then ran npm install for each module not present, but there are many of them. Is there a way to install all the requirements? Something like pip install -r requirements.txt in Python.
Thanks,
Uri.
Just run npm install without arguments. It will resolve the required dependencies from the package.json file.
It's simple.
If you want to install all the node_modules from the package.json file you simply put: npm install in terminal (on the same directory where the package.json exists) and it would install all the node modules in the folder called node_modules.
Generally, the node_modules folder is not uploaded in a git (by putting restriction at .gitignore) because it is essentially the same folders or packages that one would have to install, *hence installing it from package.json is simpler and it saves the internet bandwidth and time.
Even you want to save something in the package.json while you are installing any npm package you can simply put npm install --save your-package-name and it would automatically save your package in the .package.json file and you can install the same file, even after you delete the node_modules folder using the same command.
Better yet, if you want to save yourself a lot of time use yarn install instead of npm install (https://yarnpkg.com/en/). It is much faster because it caches everything and operates in parallel (see https://www.sitepoint.com/yarn-vs-npm/ for a good comparison).
npm install githubname/reponame -- Repository Name you can try
I have an issue with a project where we are using node and brunch. The issue is current specific to brunch, but could occur for any module would be my guess.
The easiest way to currently reproduce this, is to do the following in a new folder:
npm init
npm install --save-dev brunch
The issue here is that brunch depends on loggy, which in turn depends on ansi-color, which no longer has an entry in the npmregistry:
https://registry.npmjs.org/ansi-color
I think this might be the github project: https://github.com/loopj/commonjs-ansi-color
In any case, I am unable to proceed, and all our builds fail because they are not able to fetch the given dependency.
I could perhaps use npm shrinkwrap in some way, but that depends on the modules already existing in node_modules, which I am currently missing.
So how can I force npm to use ansi-color from a different location, or ignore the dependency?
Not sure about npm 2 but you can fix this with beta npm 3. npm 3 has flat node_modules directory. So sub modules can sit in the top level. Read the Changelog.
The missing modules can be installed directly from their Github repo as a toplevel dependency in your project. If npm finds the module with the same version in node_modules directory, it won't look for it anymore in the registry.
Install npm 3:
npm install -g npm#3-latest
Then install depencies:
//install missing module from other location
npm install https://github.com/loopj/commonjs-ansi-color.git --save-dev
npm install --save-dev brunch
It looks like ansi-color is back on the npm registry ("https://registry.npmjs.org/ansi-color" is back online)
I create my Node project (npm init). In this project, i want to use Node REST Client from git hub https://github.com/dchester/node-rest-client.
update package.json with dependency:
...
"dependencies": {
"rest-client": "*"
},
...
create dir node_modules in my project
Copy the rest-client into the directory 'node_modules'
Run 'npm install' to install this dependency, however it doesn't.
What am i doing wrong? how to properly install dependency that is not from npm central repo?
Thank You
It looks like you'll have to do it manually for every module. However as the accepted answer in How to install a private NPM module without my own registry? by Mihai points out, npm knows about git:
npm install git://github.com/visionmedia/express.git
furthermore, besides going into the directory and typing npm install there it is possible to specify the path as argument:
npm install path/to/somedir
There's another useful answer in How to install a private NPM module without my own registry? where you can see you can also specify a url pointing to a tarball. I suggest you take a look at that thread.
As I started to develop my first nodejs express application, I added many packages with npm.
I would like to know if there is a way to generate a package.json file containing all the current dependencies or the list of the current packages under the nodes_modules directory.
Just run npm init in the same directory as your project.
You'll be asked a list of questions (name, version, description, etc.) and once complete, it will generate a package.json file with all of the dependencies as currently installed in the node_modules directory.
Run npm list to see what you have installed. Run npm shrinkwrap to build a npm-shrinkwrap.json file, which you can use as a starting reference to build a proper package.json. My workflow is always to update package.json and then run npm install. I never run npm install foo to get some package because it creates risk of forgetting to add it to package.json and then having your application fail to start on deployment.
Updated to add: These days I do run npm install --save foo or npm install --save-dev foo since I have now decided the ~0.4.3 version numbers it adds to package.json are better than my former preference for 0.4.x since the ~ gives you a more precise minimum version number.
