[ACCEPTED]-Ruby on Rails: permission denied when using "rails generate controller welcome-ruby-on-rails-3

I solved that problem by running

sudo chmod -R 1777 /tmp

hope this 2 helps other people like me who would prefer 1 not having to deactivate the spring gem

It needs ownership to write the re-write 3 the pid for each server start.

I had to 2 run it with my full local path & sudo

$ sudo 1 chmod -R 777 /Users/MyName/Desktop/projects/my_project/tmp/

I took a look at the library that's trying 5 to write the pid file, lib/spring/env.rb.

The function in 4 question tries to create a temporary directory 3 at the same location each time unless the 2 XDG_RUNTIME_DIR is set:

path = Pathname.new(File.join(ENV['XDG_RUNTIME_DIR'] || Dir.tmpdir, "spring"))

Setting said variable to a unique 1 directory does the trick for me:

export XDG_RUNTIME_DIR=/tmp/`whoami`

Missing permission for tmp folder to writable 1 . run chmod 777 tmp/

I had this same issue when working on a 21 Rails 6 application in Ubuntu 20.04.

Each 20 time I run the command rails assets:clobber to remove the old 19 assets in public/assets completely, I get the error:

errno::enotempty: directory 18 not empty @ dir_s_rmdir

errno::eacces: permission 17 denied @ apply2files

And the logs pointed 16 the path to the file causing it, which in 15 my a case was the public/packs/manifest.json file.

I tried deleting 14 it or changing permission but nothing worked. I 13 also tried deleting the tmp directory in the 12 project, but it did not work.

Here's how I fixed it:

I listed all 11 the files and directories in that directory 10 using the ls -lh command, which gave me this output:

-rw-rw-r-- 1 promisechukwuenyem promisechukwuenyem 1.7K Oct  6 20:29 404.html
-rw-rw-r-- 1 promisechukwuenyem promisechukwuenyem 1.7K Oct  6 20:29 422.html
-rw-rw-r-- 1 promisechukwuenyem promisechukwuenyem 1.6K Oct  6 20:29 500.html
-rw-rw-r-- 1 promisechukwuenyem promisechukwuenyem    0 Oct  6 20:29 apple-touch-icon.png
-rw-rw-r-- 1 promisechukwuenyem promisechukwuenyem    0 Oct  6 20:29 apple-touch-icon-precomposed.png
drwxr-xr-x 3 promisechukwuenyem promisechukwuenyem 4.0K Oct 13 09:20 armstrong_tools
-rw-rw-r-- 1 promisechukwuenyem promisechukwuenyem    0 Oct  6 20:29 favicon.ico
drwxr-xr-x 3 root               root               4.0K Oct  8 13:06 packs
-rw-rw-r-- 1 promisechukwuenyem promisechukwuenyem   99 Oct  6 20:29 robots.txt

I 9 realized that the permissions for the files 8 and directories were fine, however, the 7 packs directory had root ownership which was seperate 6 from persmission of other files and directories:

drwxr-xr-x 3 root               root               4.0K Oct  8 13:06 packs

I 5 simply ran the command below to change the 4 ownership from root to promisechukwuenyem:

sudo chown -R promisechukwuenyem:promisechukwuenyem packs/

Now 3 when I ran the command rails assets:clobber to remove the old 2 assets in public/assets completely, it worked just fine.

That's 1 all.

I hope this helps

I am getting this type of error(permission 2 denied @ apply2files) when using rails server.

sudo rails server solve 1 my problem.
