Are you sure the three dots isn’t a typo? (Is it intended to be ../ instead of .../?) If not, what is the desired behavior? (If I recall, you could use ... in DOS, and it was equivalent to Unix ../.., i.e., the directory above the directory above the current working directory.)
no, the syntaxis is right in Unix. …/ is the directory above. The solution is simple: call docker from the parent directory and then go to the src directory, in this way the syntaxis …/ works.
By the way, the command fenicsproject run does not work on macOS 10.14.6.
(using Docker instead)
