rails 6 webpacker in production: rake assets:precompile fails

Question

I have a typical rails 6.0.2 app set up on a production server and I'm using git hooks to deploy the app. When I try to run: rails assets:precompile I get the following error:

rake aborted!
Sprockets::ArgumentError: link_directory argument must be a directory
/home/user/myapp/app/assets/config/manifest.js:2

Here is the manifest.js file

//= link_tree ../images
//= link_directory ../stylesheets .css

I cant figure out what Im doing wrong. Unless I'm mistaken, doesn't webpacker replace sprockets?

Answer 1

For anyone else who got this error, I simply added a directory in assets , called stylesheets , and added a file .keep within it. That fixed my problem.

Answer 2

In manifest.js , your error tells that in manifest.js line 2, link_directory argument must be a directory, and not a file. It should probably look like this

//= link_directory ../stylesheets .css

If you notice there is gap between stylesheets and .css , it means that link all the css files from stylesheets directory, there must be some formatting problem in your code. Fix it and it should work!

Answer 3

double check all the asset folder for an empt .keep file

common culprit could be images folder

Answer 4

在images和javascript文件夹中添加一个.keep文件为我修复了它。
