Creating an environment fails with "post-link failed for..."

[stmax82]

I'm trying to create a new environment. I get several "The system cannot find the file specified." errors followed by the error "post-link failed for: pyqt-4.11.4-py34_3".

OS is Win8 x64, conda version is 3.18.5.

Below is the complete console output.

I noticed that the problem only happens when one of the parent directories contains a "!" character. :)

Having the same issue right now, did you manage to solve it?

[msarahan]

Sorry, this might also be a package installation order problem. The Qt package creates a file that the PyQt packages uses. Unfortunately, packages are getting installed alphabetically. We are working on this issue. For now, a workaround is to just reinstall pyqt after activating your new env:

conda install -f pyqt

[stmax82]

For me the problem only happens when I'm in some directory that contains a "!" bang character. The error hasn't happend again since I moved all my projects into another directory.

I just tried this and it's still reproducible:

cd c:\temp
conda create -p pyenv python=3.4 scikit-learn pandas matplotlib scipy ipython-notebook

=> works flawlessly

mkdir c:\temp\bang!
cd c:\temp\bang!
conda create -p pyenv python=3.4 scikit-learn pandas matplotlib scipy ipython-notebook

=> fails with error:

The system cannot find the path specified.
The system cannot find the file specified.

I am having a similar issue trying to setup a new environment with

conda create -n py34 python=3.4 anaconda

I have then tried to force install of qt and pyqt with no success:

`conda install -f qt

The following specifications were found to be in conflict:
qt
Use "conda info " to see the dependencies for each package.`

Also if I do a conda list on the new environment any package that comes alphabetically after pyqt is not installed. Any thoughts or suggestions?

Problem seems to be fixed - I cannot reproduce it anymore. Close?

[tombardo]

I haven’t tried in a while. I say close it.
