23,932 Pointsnpm install bcrypt & also python --version
When i run npm install bcrypt it downloads 111 packages as where the instructors screen shows it only downloaded 1 package (the bcrypt package). I also get a completely different result than Andrews with different WARNINGS.
RESULT
Jaycode@jaycode-pc MINGW64 /c/xampp/htdocs/npm_treehouse
$ npm install bcrypt
> bcrypt@1.0.3 install C:\xampp\htdocs\npm_treehouse\node_modules\bcrypt
> node-pre-gyp install --fallback-to-build
[bcrypt] Success: "C:\xampp\htdocs\npm_treehouse\node_modules\bcrypt\lib\binding\bcrypt_lib.node" is installed via remote

+ bcrypt@1.0.3
added 111 packages in 12.513s
ADDITIONALLY after I've downloaded the packages when I type python --version
I get the following error message.
Jaycode@jaycode-pc MINGW64 /c/xampp/htdocs/npm_treehouse
$ python --version
bash: python: command not found
PS. Not sure if it makes a difference but I'm using Visual Studio Code on a Windows 10 64-bit operation system.

23,117 PointsTwo things, 1. do you have a package.json file set up? and 2. you do not have python installed on your computer. Since you are running on Windows, it will be different for the course you will need to download Python.
In the future it's important to be able to read error messages:
npm WARN enoent ENOENT: no such file or directory, open 'C:\xampp\htdocs\npm_treehouse\package.json' - means that the file package.json does not exist.
$ python --version bash: python: command not found - this means that python does not exist because it can not find the command python --version.

23,932 PointsJacob Mishkin I just downloaded python, but don't have the package.json file. I don't recall instructor saying we need either, but this is good to know. Where can I get the package.json file for this lesson? I don't see anything in the teachers notes.
I will have to try and do better in learning to read these error messages. They can be mind boggling for someone who is new to this.

23,117 PointsTo get started with NPM the first thing to do is in the console write npm init. this will create a package.json file and from there you can install packages like from the videos.
PS During the init process, you will be asked several questions, if you don't know the question being asked don't worry just hit enter and you'll be fine.

23,117 PointsLearning how to read an error message is a process like anything else. You will always run into them and being able to read that they are saying really helps in debugging.

23,932 PointsJacob Mishkin Thanks for your answer. One more question if I may. When i run npm install bcrypt or even
npm install --python=python2 Why does it download 111 package folders? Shouldn't it only download the 2 packages specified?
Jacob Mishkin
23,117 PointsThis is a hot topic when talking about NPM packages. Your package might have a dependency or several dependencies in order to use. So if I want to use X I might need to also download Y & Z packages so X runs.

23,932 PointsThanks again Jacob Mishkin . Good to know. I better understand now. I kind of suspected that, but wasn't sure because the folder structure in the Instructors video screen is completely different.
Jacob Mishkin
23,117 Pointsyour node_modules folder is different or folder structure in general?
jlampstack
23,932 PointsJust the node_modules folder.
Jacob Mishkin
23,117 PointsCool. The reason for this is because you are on a Windows machine and he is using workspaces/Mac. This will require different dependencies so the node packages will run.

23,932 PointsAwesome, thanks, i was convinced I was doing something wrong or missed a step, but this is great to know!
Jacob Mishkin
23,117 PointsNot a problem. If you run into more issues feel free to post them with your code.
