我pyenv在 Ubuntu 16.04 上安裝了多個 Python 版本。我創建了虛擬環境來處理使用不同版本的項目pipenv。然而，為Python 3.5.x的只有我得到這樣的錯誤，當我嘗試用Vim編輯8（通過安裝的文件PPA）在激活的virtualenv："test.py" 49L, 1434CError detected while processing function jedi#init_python[4]..<SNR>48_init_python[27]..jedi#setup_python_imports:line   25:Traceback (most recent call last):  File "<string>", line 1, in <module>  File "/home/user/.local/share/virtualenvs/test-AYf6DmHL/lib/python3.5/imp.py", line 19, in <module>    from importlib._bootstrap import _ERR_MSG, _exec, _load, _builtin_from_name  File "/home/user/.local/share/virtualenvs/test-AYf6DmHL/lib/python3.5/importlib/__init__.py", line 57, in <module>    import types  File "/home/user/.local/share/virtualenvs/test-AYf6DmHL/lib/python3.5/types.py", line 166, in <module>    import functools as _functools  File "/home/user/.local/share/virtualenvs/test-AYf6DmHL/lib/python3.5/functools.py", line 23, in <module>    from weakref import WeakKeyDictionary  File "/home/user/.local/share/virtualenvs/test-AYf6DmHL/lib/python3.5/weakref.py", line 12, in <module>    from _weakref import (ImportError: cannot import name '_remove_dead_weakref'這個問題似乎影響了所有與 python 相關的 Vim 插件。對于其他 Python 版本（例如 3.6.x、3.7.x），不會發生這種情況。什么可能導致這個問題？更新：似乎當我在 3.5.x virtualenv 中運行 Vim 時，Vim 的解釋器sys.path會以某種方式更新。例如，這是:py3 import sys; print(sys.path)3.6.0 virtualenv 內部的輸出：['/usr/lib/python35.zip', '/usr/lib/python3.5', '/usr/lib/python3.5/plat-x86_64-linux-gnu', '/usr/lib/python3.5/lib-dynload', '/usr/local/lib/python3.5/dist-packages', '/usr/lib/python3/dist-packages', '_vim_path_']這是 3.5.3：Traceback (most recent call last):  File "<string>", line 1, in <module>  File "/home/testuser/.local/share/virtualenvs/venv-3.5-8feRiT5s/lib/python3.5/imp.py", line 19, in <module>    from importlib._bootstrap import _ERR_MSG, _exec, _load, _builtin_from_name  File "/home/testuser/.local/share/virtualenvs/venv-3.5-8feRiT5s/lib/python3.5/importlib/__init__.py", line 57, in <module>    import types該問題可以在ubuntu:16.04docker 容器中重現。
