Dependency installation failing using prescribed method #18

Closed ghost closed 3 years ago

ghost commented 3 years ago

I am trying to install dependencies according to instructions but am getting a failed response.

May I just install them using pip install dependency?

I am using pyenv for my python install on macOS Big Sur. 

$ pip install --upgrade webchanges[use_browser]

Suggestion: In your example code don't include brackets. Just use the code as it should be entered - sans brackets. The wording and the example work together to make it seem as though they are a required part of the command.

as shown:

pip install --upgrade webchanges[use_browser]
pip install --upgrade webchanges[use_browser,redis]

whereas this is the correct command:

pip install --upgrade webchanges pushover

Using the new format some dependencies aren't found:

$ pip install --upgrade webchanges safe_password

$ pip install --upgrade webchanges use_browser

Looks like its a ZSH issue for some reason. Can't understand it.

Not sure what to do because I incorrectly assumed that the command didn't require brackets. In fact pip was seeing it as a list of packages to install. It looks like those packages weren't linked correctly to webchanges.

I switched to the BASH shell and used the syntax you provided and the command worked but now I am thinking I have duplicate packages installed? How can I remove or fix this issue?

Thanks for opening the issue.

As you found out, the syntax is for setuptools extras and is correct with brackets as per pip examples. It also works (see below).

I recommend you open an issue with ZSH and/or pip.

I am sorry you had to go through this but it nothing that this project can fix (and I don't use ZSH). But please do update this issue if you find anything useful that can be added to the documentation for future users!

I just moved from bash to zsh a day ago so... bound to be "features" I am unaware of. Hope this helps others. Maybe include this in your documentation?

In zsh shell [ does pattern matching. Brackets need to be escaped: \[package\]

$ python -m pip install --upgrade webchanges\[use_browser\]
