Functional tests do not run anymore : momentjs has circular symbolic link
jbgury opened this issue · comments
Description
Functional tests do not run anymore on develop branch or master branch.
Travis CI performs the install operation. During the static resources collect from django, a circular reference of symbolic link is detected and causes exception.
The circular reference is on the momentjs dependency.
Expected behavior
Functional tests have to run correctly on the CI
Actual behavior
From one execution on the CI without change on the code, the dependency has circular symbolic link.
Analysis
Something changed on the process :
- either the momentjs dependency is used with a buggy version
- either the CI does not manage correctly this dependency
Analysis
Travis CI uses yarn v1.22.4 by default (the last published version). Great, but it causes some troubles.
When the step : python ./manage.py collectstatic --no-input is executed, the error
OSError: [Errno 40] Too many levels of symbolic links: '/home/travis/build/libreosteo/Libreosteo/libreosteoweb/static/components/moment/meteor/moment.js'
After analysis, the problem occurs from the v1.22.0.
This problem is known by yarnpkg/yarn#7890
The workaround of this issue is to switch and stay on the v1.21.1.
Readme has to be updated, on Debian unstable stream,the provided version for yarn is v1.22.1
An alternate solution has to be provided into Readme
