Missing numpy dependency when installing via pip

[rleigh-codelibre]

If numpy is not already installed, installation will fail.

If numpy is manually installed, installation will succeed.

Example runs shown below.

$ python3 -m venv /tmp/test-libtiff
$ . /tmp/test-libtiff/bin/activate
(test-libtiff) $ pip install libtiff

also experiancing the same issue.... anyone has a workaround that doesnt involve installing directly?

You need to install:

pip install pylibtiff

Pip, setuptools, and pylibtiff have changed a lot since this was originally created. Closing now but if someone is still having this issue with modern versions of everything then please open a new issue.

I created https://github.com/pearu/pylibtiff/issues/180. It doesn't look like there has been any change at all. It still fails in the same way originally reported. The stack trace is slightly different but the cause is the same.
