npm install does nothing - how make it work?

问题

I have a trouble with npm and I haven't found solution in web.

Today I wanted to start my adventure with nodejs, npm, bower etc.

I use Windows 8.1.

I installed the newest nodejs (v0.12.0). I tried these steps with both x64 and x86 builds. I opened nodejs command line with administrative privileges. I updated npm to 2.5.0 version. When I run npm install bower -g I see a char that seems to show progress (it'is rolling) but nothing happens. Even if I leave it "working" for a 30 minutes, nothing happens. It never ends. When I type np ls -g it shows only npm@2.5.0 and it's dependencies.

I don't know what other info I could provide. There are no errors nor logs. Please, help.

Thetoast found solution that worked for me.

If you have the same problem check the value of your TEMP environment variable. To do so run nodejs' command window and type

echo %TEMP%

You should receive path to a single directory. If you receive multiple directory (as I did - I received C:\Users\<user>\AppData\Local\Temp;c:\Users\<user>\AppData\Local\Atlassian\SourceTree\git_local\bin\) it means that this might by the cause of the problem. You can fix it by typing

SET TEMP=<correct path to temporary directory>

where <correct path to temporary directory> might by the first path (before semicolon, that means C:\Users\<user>\AppData\Local\Temp in my case).

I had some issues with the npm install bower -g aswell but try this command:

npm install bower --global

this one worked for me

I know this is an old question but i am adding this answer just for the record.

I was facing a similar issue i.e. rotating character with no progress in actual installation after trying to install using the following command on linux Mint 17(from http://bower.io/#install-bower):

npm install -g bower

The command which actually worked for me is:

npm install --global bower

Note: You will need root/administrative privelage to run this command. So you might wanna use sudo.

I was getting the same error. But I found that this was Windows Firewall problem.

Make sure your firewall is not preventing any Incoming connections or there is no limit on TCP connections.
