Hello,

I run the command : nvmw install latest

C:\Projects\loyalty>"C:\Program Files\nodejs\node_modules\nvmw\bin\nvmw.bat" install latest
Downloading Node vlatest...
Node vlatest downloaded failed

I get the same error when i am giving the specific version : nvmw install v.4.1.1

I tried to install earlier versions...works fine.

Thank you.

Any plans to add support for a command like the ls-remote of the original nvm?

As title, can nvmw install current version when without version argument passing to nvmw install.

Thanks!

function downloadFile(url, filename, callback) {
//var xhr = WScript.createObject('Msxml2.XMLHTTP')
var xhr = WScript.createObject('Msxml2.ServerXMLHTTP')
, ostream = new ActiveXObject("Adodb.Stream");

Is there a way to choose between x86 or x64 installation of Node?
Right now, the x86 version is installed.

In China,taobao's mirrors is http://npm.taobao.org/mirrors/node/v4.1.1/win-x64/, path is win-x64 not x64.

i've installed the latest node version, i'm using nvmw install 8.10.0 to change the version, but i get the following error : Downloading Node v8.10.0 failed

I’ve copy-pasted the command from your README, and executed it in PowerShell (while in C: directory):

git clone git://github.com/hakobera/nvmw.git "%HOMEDRIVE%%HOMEPATH%\.nvmw"

As a result, this directory was created:

C:\%HOMEDRIVE%%HOMEPATH%\.nvmw

Notice how the string was interpreted literally, instead of transforming the %HOMEDRIVE%%HOMEPATH% part into C:\Users\simev (in my case).

Is this a new issue on Windows 10?

Is there a way to execute install silently to be called from a build script?

I am not sure if I'm doing something wrong, and please correct me if I am. I have node v0.12 installed and I have recently installed nvmw to try to run koajs on my work machine. When I tried nvmw install v0.11.16 I get the following:

What could be happening here? Did I miss any step?

When I run nvmw install, it fails the first time with a "Can't get npm" error. If I run the command again, it works. Windows 7 SP1.

When I use the current version and try to run

nvmw install 0.10.31

It seems to download the npm.zip file correctly to the v0.10.31 file, however, when it attempts to run the unzip process on it:

cscript "%NVMW_HOME%\unzip.js" "%NPM_ZIP_FILE%" "%NODE_HOME%"

The process cannot access the file because it is being used by another process. At least that's what I'm guessing from a cursory reading. Here is the full output that's failing:

The npm installing was failed (network problem, maybe), but any error doesn't occur, and a version without npm was set to using.
I think that an error should occur, but this behavior has some reason?

https://github.com/hakobera/nvmw/blob/master/nvmw.bat#L154

  if not exist %NPM_ZIP_FILE% (
    exit /b 0;
  )

  if not exist "%NPM_ZIP_FILE%" goto install_error

(And, I think that that path should be quoted.)

running nvmw use anyversion doesn't set the alias for node nor npm, is this something on my end?

I've already fixed nvmw.bat and some other locations (see my comments in #75)

appear the error like this:
I also have try do like this : set "NVMW_NODEJS_ORG_MIRROR=https://npm.taobao.org/dist", but it don't work. occur error like:' Can't get 'content-length' ' .etc
what's happening?

Anyone know where this error is coming from? (Win7 x64)

first i found the url which to download node is wrong,and i fix it :

Hi guys,
I just found that I've messed up the packages and I'm using NVMW from npmjs.com (which points out to https://github.com/nanjingboy/nvmw). There I have an AWFUL issue: nanjingboy/nvmw#5
Because I don't fully understand your code - if you ever hardcode the PATH variable anywhere - please remove this, as it's causing severe problems!

Thanks!

I have not installed node via msi.
I open a command prompt and type "nvmw use v0.10.13"
Then i can execute node and npm commands normally.
But when closing the command prompt and reopen an other one, Windows forgets node ...
So I have to execute "nvmw use v0.10.13" again (in each new command prompt)

I don't know if I have a misconfiguration or missing something, but I had to run nvmw use iojs or node each time my cmd is opened. Or else I couldn't use npm or any other global packages I've installed.

I've checked, and everything's correct, I have nvmw in my path.
But nothing for either iojs's or nodejs's npm.

So I've added nvmw's nodejs installation path into my System Path, to at least have nodejs as a default.

Is this correct? Because I can't set a default one from nvmw itself, for example if I decide to use iojs as a default, I'll have to set it myself into my System Path.

Docs would be great for this default configuration I guess.

I enter the command: nvmw install v4.1.2

and I get

ERROR: The system was unable to find the specified registry key or value.

What am I doing wrong?

I'll create pull request shortly.

nvmw install iojs 1.6.2 completes successfully however the output shows its installing npm 2.7.5 (which is associated with iojs 1.6.4) and upon running iojs -v I get 1.6.4.

Any ideas? I've tried with fresh install of nvmw/iojs etc.

Thanks!

It seems bat file doesn't work in Git Bash.
Or is there any other way to make it work in Git Bash?

thanks~

Probably a stupid question, but how do I upgrade latest in place, e.g., from 0.12.6 to 0.12.7? What I've been doing so far is:

nvmw use [something-else-than-latest]
nvmw uninstall latest
nvmw install latest

but that loses my node_modules and bin scripts, so it can take up quite a bit of time.

Perhaps nvmw install latest needs an option to bypass the check if it already exists so it can just overwrite the files?

I guess a naive approach would be to copy the node_modules folder and bin scripts and just move them back after uninstalling and reinstalling?

well, I use a wrong installation command by accident: nvmw install iojs 1.8.1, and get a wrong result:

Start installing iojs/latest (1.8.1) to F:\Nodejs\nvmw\iojs\latest-1.8.1

the right one: nvmw install iojs-v1.8.1 and the right result:

Problem:

# Test 1:
nvmw install iojs-v1.2.0
nvmw use iojs-v1.2.0
iojs -p process.arch
# => x64

# Test 2:
# now install same version with x86 architecture:
nvmw install iojs-v1.2.0 x86
# you will probably notice that during the installation,
# it will ask to overwrite files when unzipping npm.zip..
nvmw use iojs-v1.2.0-x86
iojs -p process.arch

# expected: x86

# Test 3:
# now install different version with x86 architecture
# whose x64 variant is not installed:
nvmw install iojs-v1.1.0 x86
nvmw use iojs-v1.1.0-x86
iojs -p process.arch
# => x86

Proposed solution:

• Always save with architecture slug (-x86 or -x64), if the architecture is not provided in nvmw install on x64, still save with -x64 prefix.
• On nvmw use, if -x64 or -x86 is provided, do not disregard it (see Test 2 and Test 3 in above example) and throw the error if the intended {runtime}-{version}-{architecture} is not installed.
• If architecture suffix is not provided, append the system default architecture slug (-x64 on 64-bit OS).

Trying to install node v0.10.29, but fails while trying to download npm from:

Package does not exist. Maybe you would know why the package was not published? Maybe a new location or no longer distributed as a zip?

For sure, the console output from nvmw was not helpful in debugging this and it took me some time to find out what was happening.

Getting this error when installing any version of both node and iojs

A duplicate file name exists, or the file
cannot be found.
The system cannot find the path specified.
D:\

I propose a feature that let we can specify nvmw use v2.3.2 instead of nvmw use iojs-v2.3.2.
Sometimes, I type nvmw use iojs v2.3.2 by mistake.
I think that no duplicate version numbers are existing between NodeJS and iojs.

nvmw throw an error when %NODE_TYPE%\%NODE_VERSION% was not found.
It should set iojs to %NODE_TYPE% and try find again when %NODE_TYPE% is node.

The download path for Node v4.0.0 is https://nodejs.org/dist/v4.0.0/win-x64/node.exe and https://nodejs.org/dist/v4.0.0/win-x86/node.exe, so running nvmw install v4.0.0 fails because it tries to download from paths like https://nodejs.org/dist/v4.0.0/x64/node.exe.

Did they change the url pattern recently?

when use nvmw install v4.1.0, the bat file build link is https://nodejs.org/dist/v4.1.0/x64/node.exe
but real link is "https://nodejs.org/dist/v4.1.0/win-x64/node.exe"
