I've installed Heroku Toolbelt (https://toolbelt.heroku.com/) on a Windows 7 system.
I've followed the tutorial up to here: https://devcenter.heroku.com/articles/getting-started-with-nodejs#declare-app-dependencies
When I run the command npm install it gives the following error:
'npm' is not recognized as an internal or external command, operable program or batch file.
I understand this means it can't find/execute npm. But this is going from Heroku's own tutorial/documentation, in sequence, and doesn't say you need to install anything else to get this working. When I go to the npm website (https://www.npmjs.com/) it also says:
The npm command-line tool is bundled with Node.js. If you have it installed, then you already have npm too.
Something is wrong with this!
Try to reinstall nodejs. Alternatively, you can install nvm for windows, which is a version manager for nodejs. It's pretty useful and easy to install. Check it out at https://github.com/coreybutler/nvm-windows

I have installed Preact but it’s not getting recognized in the terminal. First, I went to the official website of PreactJS. The doc says that I have to run npm install -g preact-cli. As I am using Yarn, I ran yarn global add preact-cli. It was installed successfully but with a lot of warnings. Then I ran preact create default first-preact-app. But it's showing an error that "The term 'Preact' is not recognized as a name of a cmdlet, function, script file or executable program."
I have tried force cleaning the cache and reinstalling preact-cli. But it doesn't work. Two of the warnings are that preact and preact-render-to-string have unmet peer dependency. So, I have installed them also. But it still doesn't work.
I have tried running npm and experimented with the commands also. But it didn't work. So, how can I fix the problem?
I have run these commands using Powershell and Git bash on Windows 10. I am trying to install Preact 10.5.12 using Yarn 1.22.5. And a point to be noted, I tried running yarn dlx but it returns an error that "command not found". And when the installation of preact and preact-render-to-string gets finished, yarn gives and warning that they have no binaries.
EDIT: Perhaps, it was a problem with Windows. The problem has gone after reinstalling it.
Your problem almost certainly is that preact-cli was not on your PATH - a list of programs that are globally accessible.
For what it's worth, we don't recommend installing globally. The site may still say that but the repository correctly recommends using npx instead.
I am new to the product and have minimal coding knowledge. I need to install the testcafe-vue-selectors plugin but the instructions on the github page are lacking detail. The say Install "$ npm install testcafe-vue-selectors" Where do I run this command?
Thanks and sorry for my lack of knowledge.
I assume that you have already installed TestCafe by running a single command in your terminal (command-prompt):
npm install -g testcafe
To install the plug-in, you need to execute a similar command in your terminal (in your project folder):
npm install testcafe-vue-selectors
No additional steps are required. Just ensure that Node.js and npm are installed on your computer.
I create a node application and it is running on the local server. I need to run it on my online server. I have to install npm. When I run the command npm install I got this message.
How can I fixed this issue?
try using
sudo npm install -d
npm should not need sudo except for global installs. Let's start with "how did you install node"? If you're on OSX, use brew to install the latest version, if you're on Windows, grab the installer from nodejs.org, if you're in linux, you should already know what to do
I am running Windows 8.1 with node version 7.7.3 and npm version 4.1.2.
I have been working on an Angular tutorial without issues. At some point since finishing that tutorial I installed Python. I am not sure if it is related, but I have mentioned it just in case.
Today I am trying to create an Angular application and it hung without completing.
I did some research and it tells me to do this:
npm uninstall -g #angluar/cli
npm cache clean
npm install -g #angular/cli
The last command hangs at this point:
loadRequestedDeps: silly install loadAllDepsIntoIdealTree
I opened the command prompt "run as administrator" to run these commands.
Everything I try fails. I have connected to a completely different network to eliminate that as the problem and that didn't fix anything. I have uninstalled and reinstalled node.js and that hasn't fixed the problem either.
I can ping registry.npmjs.org just fine.
What is causing this error?
I finally found the answer! I ran the following command in the command window:
echo %temp%
It had 3 temp paths in there. I removed the two I didn't need and voila, it works!
I've installed nodejs, and have used npm to install grunt using
npm install grunt
When I try to run grunt, I am presented with what appears to be instructions on running node commands: (see image)
the same applies when trying to run gulp
I have done the same steps on other computers, and had no problem running grunt previously
Please suggest ideas as to what's going on.
Thanks
As suggested by Joe Clay, the problem was that there was another app called node.exe whose pathwas in PATH variable before nodejs.
