Answer 1

Running just "npm install" will look for dependencies listed in your package.json. The error you're getting says that you don't have a package.json file set up (or you're in the wrong directory).

If you're trying to install a specific package, you should use 'npm install {package name}'. See here for more info about the command.

Otherwise, you'll need to create a package.json file for your dependencies or go to the right directory and then run 'npm install'.

Answer 2

I had this problem when trying to run 'npm install' in a Terminal window which had been opened before installing Node.js.

Opening a new Terminal window (ie bash session) worked. (Presumably this provided the correct environment variables for npm to run correctly.)

Answer 3

在我的情况下，这是由于其中一个依赖项的 URL 错误（ http://而不是git:// ，最后没有.git ）。

Answer 4

You're likely not in the node directory. Try switching to the directory that you unpacked node to and try running the command there.

Answer 5

如果它对其他人有帮助 - 我的问题是一个新手错误，我的 package.json 的名称行中有一个空格，它导致依赖项不可读。

Answer 6

I came across this, and my issue was using an older version of node (3.X), when a newer version was required.

The error message actually suggested this as well:

...
Make sure you have the latest version of node.js and npm installed
...

So the solution may be as simple as upgrading node/npm. You can easily do this using nvm , the "Node Version Manager"

After you've installed nvm , you can install and use the latest version of node by simply running this command:

nvm install node

For example:

$ nvm install node                                                             
Downloading https://nodejs.org/dist/v8.2.1/node-v8.2.1-darwin-x64.tar.xz...
######################################################################## 100.0%
Now using node v8.2.1 (npm v5.3.0)

$ node --version                                                               
v8.2.1

Answer 7

In mac you might have downloaded and installed Node js in /Users/yourusername/Downloads/nodejs-todo-master , so go here and run npm install command, no need of sudo as well., you should get output like this...

underscore@1.4.4 node_modules/underscore

ejs@0.8.8 node_modules/ejs

redis@0.8.6 node_modules/redis

This is all because you are not in the desired directory. You need to first get into the desired directory. Mine was angular-phonecat directory. So I typed in cd angular-phonecat and then npm install .

npm install -d --save worked for me. -d flag command force npm to install your dependencies and --save will save the all updated dependencies in your package.json

If someone is in my situation facing this error and have tried all the above solutions, like:

• you are in the right directory
• you have a package.json file,
• the JSON is valid,
• you have tried to run %temp%
• you have tried " npm install -d --save" etc.

Mine worked by doing "npm install --force"
