ImportError: No module named 'bottle' - PyCharm

Solution 1:

in your PyCharm project:

• press Ctrl+Alt+s to open the settings
• on the left column, select Project Interpreter
• on the top right there is a list of python binaries found on your system, pick the right one
• eventually click the + button to install additional python modules
• validate

Solution 2:

In some cases no "No module ..." can appear even on local files. In such cases you just need to mark appropriate directories as "source directories":

Solution 3:

The settings are changed for PyCharm 5+.

• Go to File > Default Settings
• In left sidebar, click Default Project > Project Interpreter
• At bottom of window, click + to install or - to uninstall.
• If we click +, a new window opens where we can decrease the results by entering the package name/keyword.
• Install the package.

• Go to File > Invalidate caches/restart and click Invalidate and Restart to apply changes and restart PyCharm.

Solution 4:

I am using Ubuntu 16.04. For me it was the incorrect interpretor, which was by default using the virtual interpretor from project.

So, make sure you select the correct one, as the pip install will install the package to system python interpretor.
