PyCharm import external library

python import pycharm

I am using PyCharm as an editor for python code in Houdini. Whenever I try to import the main Houdini library (hou) I get an error flagged in PyCharm. If I include the code snippet:-

try:  
   import hou  
except ImportError:  
    # Add $HFS/houdini/python2.6libs to sys.path so Python can find the  
    # hou module.  
    sys.path.append(os.environ['HFS'] + "/houdini/python%d.%dlibs" % sys.version_info[:2])  
    import hou

my code executes, without problem, from both Houdini and my selected interpreter.

My problem is with PyCharm itself. The editor flags 'import hou' as an error and any subsequent files that import this file flag modules imported by this file as errors as well. Hence I loose type ahead functionality and get an over abundance of error messages that make it hard to spot the real problems.

How do I get PyCharm to recognize the path to the hou module.

I have tried, for a couple of days, to Google a solution to this problem but they all seem to refer to tabs and settings that are not in my version of PyCharm (Community Edition 3.4.1). E.G. my 'Project Interpreter' setting only has a list of Packages and has no 'path' tab as stated in many 'fixes' to closely related problems.

Let Me Tink About It

Since PyCharm 3.4 the path tab in the 'Project Interpreter' settings has been replaced. In order to add paths to a project you need to select the cogwheel, click on 'More...' and then select the "Show path for the selected interpreter" icon. This allows you to add paths to your project as before.

My project is now behaving as I would expect.

Loving the Jetbrains products, but boy are they good at hiding certain things. (-;

As of PyCharm 2018.3.4 CE (2019-Feb-01), on ubuntu 18.04, they've again changed the location. Refer to Hghowe's answer below

God, that's crazy UX. Thank you.

Can you do the same for a remote python interpreter!? When having your code locally but using a remote interpreter on a more powerful machine?

Answer for PyCharm 2016.1 on OSX: (This is an update to the answer by @GeorgeWilliams993's answer above, but I don't have the rep yet to make comments.)

Go to Pycharm menu --> Preferences --> Project: (projectname) --> Project Interpreter

At the top is a popup for "Project Interpreter," and to the right of it is a button with ellipses (...) - click on this button for a different popup and choose "More" (or, as it turns out, click on the main popup and choose "Show All").

This shows a list of interpreters, with one selected. At the bottom of the screen are a set of tools... pick the rightmost one:

Now you should see all the paths pycharm is searching to find imports, and you can use the "+" button at the bottom to add a new path.

I think the most significant difference from @GeorgeWilliams993's answer is that the gear button has been replaced by a set of ellipses. That threw me off.

This seems to be the right way to go for the current Linux version too.

I just wrote up how to do this on macOS in PyCharm 2018.2. Essentially what you say above, but I included more screenshots, in case that's helpful for anyone: github.com/bobtiki/pycharm-blender-mac/blob/master/README.md

Update (2018-01-06): This answer is obsolete. Modern versions of PyCharm provide Paths via Settings ⇨ Project Interpreter ⇨ ⚙ ⇨ Show All ⇨ Show paths button.

PyCharm Professional Edition has the Paths tab in Python Interpreters settings, but Community Edition apparently doesn't have it.

As a workaround, you can create a symlink for your imported library under your project's root.

For example:

myproject
    mypackage
        __init__.py
    third_party -> /some/other/directory/third_party

Wow! I have only just started using PyCharm, I spent the last 20 years of my working life using MS Visual Studio developing C++ projects, and the idea of an IDE that does not allow you to add an external resource to a project with more than a single click is crazy. I have no idea how to start implementing your solution in Windows.

@GeorgeWilliams993 mklink /J "C:\Link To Folder" "C:\Users\Name\Original Folder"

The path settings do exist in CE as well, this answer worked for me: stackoverflow.com/a/24206781

As of the year 2020, (specifically, February 2), this is the only answer that worked for me! Move this answer to the top!

If the external library is in a folder that is under the project then

File -> Settings -> Project -> Project structure -> select the folder and Mark as Sources!

If not, add content root, and do similar things.

If not, add content root This was a game changer, thank you!

Thanks a lot. I tried to add the library under my project with File -> Settings -> Project -> Project Interpeter -> "wheel" (Show All...) -> Interpreter Path, but this only helps for debugging/executing (if I'm not wrong), but definitely not for code insight. For that you need to mark the directory as source in your project structure as you say.

In my case, the correct menu path was:

File > Default settings > Project Interpreter

I wanted to add an import path, for another project elsewhere in my workspace. MacOS Catalina 10.15.5 PyCharm Community 2020.1.1

PyCharm - Preferences - Project interpreter - Cog symbol - Show All

At the bottom of that dialog, it shows 5 buttons: Plus, Minus, Pencil, Funnel, and Directory tree.

Click Directory tree. You can now use the Plus button in the new dialog to add your 'external library' search path.

If successful, you should now see the directory name in the "External Libraries" pane in the Project panel.
