vim: symbol lookup error: vim: undefined symbol: PyUnicodeUCS4_AsEncodedString

Question

Today I encountered a problem about vim:

vim: symbol lookup error: vim: undefined symbol: PyUnicodeUCS4_AsEncodedString

I didn't install any vim plugins. But I installed some Python projects(Nginx, uwsgi). Seemingly after these installations, vim crushed.

Any clues?

Answer 1

I have encountered the same problem. Here is my solution.

Type in terminal

ldd /usr/bin/vim

it showed that the python lib pointing to a location customized by me.

libpython2.7.so.1.0 => /home/ql/software/vtk/vtkpython-7.0.0-Linux-64bit/lib/libpython2.7.so.1.0 (0x00007f303b99c000)

I opened my .bashrc, finding something related to the above line:

export LD_LIBRARY_PATH=/home/ql/software/vtk/vtkpython-7.0.0-Linux-64bit/lib:$LD_LIBRARY_PATH

Then I commented the above line out.

Open a new terminal and type again:

ldd /usr/bin/vim

It can be noticed that the python lib points to some location other than that in the previous result:

libpython2.7.so.1.0 => /usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0 (0x00007f1ed4a36000)

Now vim runs.
