The directory C:\Users\me\AppData\Roaming\nvm\v8.10.0\node_modules exists, but is empty.

I have the exact same issue.

Check that your user name does not have space, in some cases "C:\Users\Name LastName\AppData\Roaming\nvm", when I changed the nvm installation folder to another location "C:\node\nvm" , the installation of node + npm worked fine.

[OrangeDog]

There are no spaces (or other odd characters) in nvm root.

I have the exact same issue also with nvm 1.1.6 and installing node 10.6.0 (or any other node version).

If I navigate to <nvm-root>/v10.6.0/node_modules the folder is just empty. This fits to the error message when trying to run npm.

 Directory of C:\Users\flawi\AppData\Roaming\nvm\v10.6.0\node_modules

09.07.2018  18:22    <DIR>          .
09.07.2018  18:22    <DIR>          ..
               0 File(s)              0 bytes
               2 Dir(s)  220.739.076.096 bytes free

If I observe the installation process after nvm install 10.6.0, I can see how npm is downloaded and extracted in C:\Users\flawi\AppData\Roaming\nvm\temp (I see the npm-v6.1.0.zip and the extracted folders). However, after the installation nothing is moved to <nvm-root>/v10.6.0/node_modules.

For completeness here is my settings.txt:

root: C:\Users\flawi\AppData\Roaming\nvm
path: C:\Program Files\nodejs

By the way, I have same issue also with nvm versions 1.1.5 and 1.1.4 (also if I use paths without spaces).

Mitigation

If you copy npm-v6.1.0.zip from <nvm-root>/v10.6.0/temp after the download is complete and extract it yourself into <nvm-root>/v10.6.0/node_modules/npm everything is working fine.

I saw this to trying to install node 10.6.0 with 1.1.5. I even ran in an admin command prompt from the get-go.

If I downloaded the 10.6.0 package from the nodejs.org website and compared it to what was in the nvm/v10.6.0 directory, what nvm installed was missing over half the npm packages.

After copying, everything worked fine, but nvm gave no indication that the install hadn't completed successfully.

#353 related?

[AvinZarlez]

I have the same issue. Installed 10.7.0, npm does not work. No spaces in nvm root

[AvinZarlez]

To clarify, I had a node_modules folder and an npm folder in it, but it was missing files and was given no errors in any of my attempts to install or reinstall. Once I deleted that npm folder, downloaded npm-v6.1.0.zip manually and extracted my npm works fine.

Similar problem (with fresh install of nvm 1.1.5 - after uninstalling node and removing any npm directories in user\AppData...). When I type npm I get the following.

So, I was having a similar problem to this and resolved it. I'll relay the steps I took to resolve it, and hopefully it helps someone.
tldr;
try: nvm install <nodeversion> <32 or 64>
nvm install 8.11.4 64

First, I installed nvm, then node 8.11.4.
Did nvm use 8.11.4
When I tried npm, windows couldn't find it, and the node_modules folder in the 8.11.4 install was empty.
Uninstalled nvm.
Tried to install nodejs straight from nodejs.org and it gave me a long filepath error.
May not need to be done, but I did it...
Edited my system registry to allow long file paths for all users ->
In regedit go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Policies and set/create a DWORD (32-bit) entry called LongPathsEnabled with a value of 1. (There's a way to do this in Windows Pro without going into the registry, but I'm on Home, and that's not an option)

---

Installed nvm again, then nvm install 8.11.4.
Got some security error.
uninstalled 8.11.4
reinstalled SPECIFYING 64-bit with command nvm install 8.11.4 64

After that, everything seems to work.
Like I said, hopefully this helps someone else, but I'm sure mileage may vary. Good luck!

I'm having the same problem with nvm 1.1.7.

• I have deleted all references to node/npm
• Clean install nvm 1.1.7
• nvm install 6.5.0
• nvm use 6.5.0
• npm install -g gulp
• Creates a npm folder in my AppData\Roaming\ folder and puts gulp in \npm\node_modules
• My AppData\Roaming\nvm\v6.5.0\node_modules only has npm folder in it

Am I missing some PATH parameters? I have %NVM_HOME% and %NVM_SYMLINK%

[dfibuch]

Further to this, it seems that even though gulp is installed into the main npm folder in Roaming, it is not being used. If I type the gulp command it can't find it, if I move the gulp files to the relevant nvm folder it works.

So it looks in the right place for its commands, just doesn't install it to the right place.

[dfibuch]

Ok I think I have found the problem. Looks like internally npm is still really holding on to the AppData\Roaming folder for its settings, one of which is the prefix. If you do npm config get prefix it will most likely point to the wrong location. You need to run npm config set prefix with the location of the special nodejs folder that nvm creates which is the %NVM_SYMLINK%. Now when I run all my npm installs it puts it in the right location, even if I switch nvm versions.

Source for fix (unrelated to nvm): https://stackoverflow.com/a/38270345/1535244

EDIT: The setting for prefix is in the .npmrc file in C:\Users\You\ folder. If for some reason that setting exists in there it will be used and it doesn't look like nvm changes it so it will always look at the wrong location. Removing this entry in this file also fixes the issue.

I'm not sure if this will help anyone, but I'll leave it here just in case. I also had this issue and I found what @dfibuch and @Flawi said was pretty useful for finding understanding the issue that I was having. So here's all my info:

• I don't have any spaces in my path
• nvm version 1.1.6
• Working with 64-bit executables
• Using Git Bash in Windows
• I did delete the setting for ; prefix=C:\Program Files\nodejs from my .npmrc and the value I was getting with npm config get prefix didn't change, it continues to be ~\AppData\Roaming\npm.

In my case, I was trying to install the latest node version (currently 10.9.0) because I needed my npm version to be >6 to be able to run npm audit, and the last node version I had installed was 8.11.3, which came with npm version 5.6.0.

Before deleting the prefix setting, when I installed node version 10.9.0 with nvm install latest 64 all I did get in my ~\AppData\Roaming\nvm folder was a new folder called v10.9.0 that only had node.exe in it, but no node_modules (it's like it wasn't even trying to install npm). After I deleted the prefix, I started to get the node_modules folder created inside nvm\v10.9.0, but I was still getting an error during installation:

$ nvm install latest 64
Downloading node.js version 10.9.0 (64-bit)...
Complete
Downloading npm version 6.2.0... Download failed. Rolling Back.
Rollback failed. remove ~\AppData\Roaming\nvm\temp\npm-v6.2.0.zip: The process cannot access the file because it is being used by another process.
Could not download npm for node v10.9.0.
Please visit https://github.com/npm/npm/releases/tag/v6.2.0 to download npm.
It should be extracted to ~\AppData\Roaming\nvm\v10.9.0

So deleting the prefix setting improved things a little bit for me, but did not solve the issue completely. I also closed everything and re-tried, so there's no way that "it is being used by another process".

After that, I decided to try @Flawi's process. I did find the npm-v6.1.0.zip file in my nvm/temp folder and tried to extract npm into my nvm\v10.9.0 folder, and that threw the error that the zip file is corrupted or has incorrect format. That might be the reason why nvm can't move it or extract it into my latest installation of node.

Maybe the issue is not completely nvm, but also the latest version of npm inside node's v 10.9.0.

I got back to using v 8.11.3 and updated npm with npm install npm@latest -g. It got updated correctly and I'm able to run npm audit. So that's why I think it could be an issue with the package inside 10.9.0 but not the package itself.

I would also like to add that I had a similar problem like @dfibuch. I installed serve globally a week ago and it got installed in a different folder than ~\AppData\Roaming\npm\version\node_modules, and also did gulp. Gulp worked anyway (I'm not completely sure why) but in order to make the serve package work, I had to copy it manually from where it got installed into my version folder inside nvm.

Upgrade to v1.1.7, which resolves #373 (issues with npm for Node 10.x.x+). The issue with spaces in the path has been resolved in master (via PR #355) and is scheduled for release in 1.1.8. If you need the functionality right now, you can build from source. I'll get 1.1.8 out as soon as I can, but there are a few other fixes still being merged in.

Closing since the aforementioned issues/resolutions should resolve this one.
