npm ERR! Error: EPERM, chmod
Solution 1
I had similar error and calling:
npm cache clean
Helped me solve it.
Solution 2
npm
is telling you that you lack the permissions to modify permissions on the affected file. This is probably a race condition, several of which were fixed in the [email protected]
codebase. I will guess that the reason you see it on one disk and not the other is that the disks have different latency and read access times, causing non-reproducible behavior.
You should upgrade to the current version of npm
(and node, for that matter). If you are using a Debian-based distribution, you can follow the instructions here < https://github.com/nodesource/distributions#usage-instructions >
curl -sL https://deb.nodesource.com/setup | sudo bash -
sudo apt-get install -y nodejs nodejs-legacy
sudo npm -g install npm@latest
If that doesn't fix your problem, please let me know; for a quicker response, create an issue on the npm
tracker https://github.com/npm/npm/issues and tag me ( @smikes ) in the issue.

If have some problems using npm on my raspberry pi when trying to build a node.js application on an usb device.
package.json looks like this:
{ "name" : "node-todo", "version" : "1.0.0", "description" : "TodoApp", "main" : "server.js", "autho" : "Stephan", "dependencies" : { "express" : "*" } }
Using npm install results in:
npm WARN package.json [email protected] No repository field. npm WARN package.json [email protected] No README data npm http GET https://registry.npmjs.org/express npm http 304 https://registry.npmjs.org/express npm ERR!

If i try to run npm install in /home/myUser/Appfolder everything works fine. All files on the ServerHD are created by the same user the homefolder belongs to. I tried using:
- npm install -no-bin-links which results in the same problems
- trying to change the folder on ServerHD to 777 has no effects for npm
- trying to run npm install with sudo
Using express-generator causes simular problems.
Hope someone can help. Thanks so far.

Salem over 9 yearsWhat partition type is in ServerHD? NTFS/FAT32?
-
Stephan over 9 yearsIt's a Fat32 partition, also used via Samba.
-
Stephan over 9 yearsI use node / npm on an arm device, so i think the version i use is the newest for this architecture.
-
Sam Mikes over 9 yearsNodesource offers an
armhf
version - ARMv7 and up.. so I think you can't use it on a raspberry pi. Then please just update yournpm
, since I don't know enough about different-architecture versions of thenode
binary. (npm is js-only)
