    Cause in the range read

    requirements.txSome of the dependent packages listed in are file path-based specifications when prepared in the local environment rather than simple versions.

    Therefore, since you have specified a path that does not exist under heroku's environment, you cannot install it.

    Action example

    The safest way isrequirements.txtI think that it is to "change the contents to the state where the file path is not specified".

    For examplepip freezeIf you use etc., it has version information instead of specifying the file pathrequirements.txtYou can fix it to.
    By committing that file, the installation will proceed even on the heroku environment.

    Command example(It may be different in the conda environment, but please check it individually)

    $pip freeze>requirements.txt

    However, if for some reason you specify the file path as a result of editing the package locally, all the edits may be missing.
    In that case, it is necessary to consider some measures separately.
