“Couldn't read dependencies” error with npm

问题:

I wanted to start a Node app and created a package.json file with a tutorial. Here is the json file:

{
    "name": "Dashboard",
    "version": "0.0.0",
    "description": "Client-A Dashboard",
    "dependencies": {
        "socket.io": "latest",
        "express": "latest",
        "jade": "latest"
    },
    "author": "tD"
}

I verified JSON file before trying to run it, but still I got an error message when I ran the npm install command:

npm ERR! install Couldn't read dependencies
npm ERR! Error: ENOENT, open 'C:\projects\Client-A\Live\package.json'

回答1:

Try to add this:

"private": true,

it worked for me.

EDIT (for people asking why):

The Oficial documentation states the following:

---

If you set "private": true in your package.json, then npm will refuse to publish it. This is a way to prevent accidental publication of private repositories. If you would like to ensure that a given package is only ever published to a specific registry (for example, an internal registry), then use the publishConfig hash described below to override the registry config param at publish-time.

---

The error messages you are getting may be related to violating this "rule" in a way (mine was).

• Either you are marking a unpublished package (like your own app) as "private": false.
• Or you are neglecting to include any value at all.

回答2:

I had an "Invalid Name"

I switched from "name": "Some Name",... to "name": "Some-Name",...

Guess name needs to be a sluggy string.

回答3:

Recently, I've started to get an error:

npm ERR! install Couldn't read dependencies
npm ERR! Error: Invalid version: "1.0"

So, you may need to specify version of your package with 3 numbers, e.g. 1.0.0 instead of 1.0 if you get similar error.

回答4:

It's simple, you're just not in the right directory.

Go to the C:\Program Files\nodejs\node_modules\npm and you should be able to run this command properly.

回答5:

Try to update npm,It works for me

[sudo] npm install -g npm

回答6:

I got the same exception also, but it was previously running fine in another machine. Anyway above solution didn't worked for me. What i did to resolve it?

1. Copy dependencies list into clipboard.
2. enter "npm init" to create fresh new package.json
3. Paste the dependencies again back to package.json
4. run "npm install" again!

Done :) Hope it helps.

回答7:

For me it was the version. Yes, the line you put at the root, like :

{
    "name": "your-project",
    "version": "0.1"
    ...
}

Yes, npm doesn't like version like this, it prefers something like "0.0.1".

Don't ask me why, I'll tell you it's totally stupid (or "how to loose time easily")

回答8:

My mistake was the I named the file packages.json instead of package.json

回答9:

I figured out I wasn't in the correct folder. I needed goto the folder I just cloned before I ran this command.

回答10:

I got this error when I had a space in my "name" within the packagae.json file.

"NPM Project" rather than "NPMProject"

回答11:

Problem with not reading the json is linked to permission issues with the file.

Using this command will do the trick:

sudo chown -R $USER:$GROUP ~/.npm

回答12:

This doesn't look like your issue, but for the sake of others, for me this was caused by an invalid version number in package.json (had to change 2.4 to 2.4.0).

回答13:

1)Nodejs installs in C:\ProgramFiles in some cases. Try installing in C: drive or another directory if you don't have admin rights.

2)Make sure you are not installing behind a company's proxy setting. This can sometimes affect installation.

3) Finally, make sure you run the npm command from this directory: Path\nodejs\node_modules\npm where Path is your own directory.

回答14:

I resolved that problem just moving my project from E: to C:. I think it happened becouse nodejs and npm was installed in my C: and the project was in my E:

回答15:

I ran into this problem after I cloned a git repository to a directory, renamed the directory, then tried to run npm install. I'm not sure what the problem was, but something was bungled. Deleting everything, re-cloning (this time with the correct directory name), and then running npm install resolved my issue.

回答16:

Verify user account, you are working on. If any system user has no permissions for installation packages, npm particulary also is showing this message.

回答17:

I was following a doc on line and thought this error meant a problem with the dependencies in NPM. however after a third look. I realized that it was a typo. I did not add a comma after the first dependency in package.json that the tutorial asked me to edit.
