"pip install -U" doesn't upgrade

[ronaldoussoren]

On at least one of my machines "pip install -U" doesn't always upgrade packages.

This might be because there happened to be a subdirectory named "build" in the current working directory that contained a extracted source archive of an older version.

Command-line output:

$ $ pip install -U pytz lxml

Not how pip downloaded lxml 2.3.5 and then says it is building 2.3.4.

After this I noticed a directory named "build" in the current working directory. After removing this directory I could perform the upgrade.

IMHO this is a bug because pip shouldn't take notice of the contents of the CWD.

Yes, this is a known bug, and should be fixed. It may already have an issue, but I'm not finding it at the moment, so leaving this open to track it.
