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

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:
Using express-generator causes simular problems.
Hope someone can help. Thanks so far.
I had similar error and calling:
npm cache clean
Helped me solve it.
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.
