Actually, it worse than I thought.  Uninstalling the user-installed version of the UI bundle is not doable from within ChimeraX.  And uninstalling ChimeraX and reinstalling it doesn't help, because that only takes care of system files, not any of the user's customization. To get rid of the user installed bundle, the first step is to find where on the filesystem the files are.  So start the Shell tool from the Tools / General menu.  And then type in it:     import chimerax     chimerax.app_dirs.user_data_dir That will  show where to go.  For example, for me on Windows, it prints:     'C:\\Users\\gregc\\AppData\\Local\\UCSF\\ChimeraX\\1.2' So using the Windows file brower, I would navigate to C:\Users\gregc\AppData\Local\UCSF\ChimeraX\1.2.   You may need to check "Hidden Items" in the View menu to navigate into AppData directory.  macOS and Linux users should have an easier time going to the correct directory.  And they would use forward slash, /, instead of backslash, \. The next step is to remove two directories: (1) site-packages\ChimeraX_UI-1.2.1.dist-info, and (2) site-packages\chimerax\ui. And then, when you restart ChimeraX, you'll be back to the version that came with ChimeraX.     HTH,     Greg On 9/27/2021 2:22 PM, Greg Couch via ChimeraX-users wrote:

Hi Haijing,

The output you pasted says that ISOLDE is already installed, so you don't need to install it again.  It should be reinstallable, so that is a bug.  If you use the graphical toolshed interface (click on More Tools... in the Tools menu), you would have seen that the install button for ISOLDE said Installed, meaning it is already installed.

In this particular case, it looks you made things worse by deliberately installing an older version of the UI bundle from the toolshed than the version that came with ChimeraX.  Using the graphical toolshed interface, you would have seen that it was a downgrade, which means do not install it unless necessary.  Or maybe you used the Updates tool to do that?  If so, you should have seen that installed version was 1.7.6 and the version on the toolshed is 1.2.1, so much older.  Regardless of how you did it, to fix it, give the command:

    toolshed uninstall ui

And that should revert back to version of the UI bundle that came with ChimeraX.  The fact that you  could install an older, incompatible, version of the UI bundle is a bug that is difficult to fix in the general case.

    Best regards,

Hi all！

I can’t install the plugin isolde using command 'toolshed install isolde'.

The conflict is caused by: chimerax-nucleotides 2.0.1 depends on ChimeraX-UI~=1.0 chimerax-opencommand 1.5 depends on ChimeraX-UI~=1.0 chimerax-savecommand 1.4 depends on ChimeraX-UI~=1.4

To fix this you could try to: 1. loosen the range of package versions you've specified 2. remove package versions to allow pip attempt to solve the dependency conflict ERROR: Cannot install chimerax-nucleotides==2.0.1, chimerax-opencommand==1.5 and chimerax-savecommand==1.4 because these package versions have conflicting dependencies. ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/user_guide/#fixing-conflicting-dependencies WARNING: You are using pip version 21.0.1; however, version 21.2.4 is available. You should consider upgrading via the 'C:\Program Files\ChimeraX\bin\ChimeraX.exe -m pip install --upgrade pip' command.
