error: externally-managed-environment
× This environment is externally managed
> To install Python packages system-wide, try apt install
python3-xyz, where xyz is the package you are trying to
install.
If you wish to install a non-Debian-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
sure you have python3-full installed.
If you wish to install a non-Debian packaged Python application,
it may be easiest to use pipx install xyz, which will manage a
virtual environment for you. Make sure you have pipx installed.
See /usr/share/doc/python3.11/README.venv for more information.
note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.

我不希望将反斜杠解释为转义序列,而是将其解释为文字反斜杠。我该怎么做?
Note that if the string should
only
contain a backslash - more generally, should have an
odd number of backslashes at the end
- then raw strings
cannot
be used
. See
如何打印单个反斜杠?
. If you want to avoid the need for escape sequences, see
如何在 Python 中编写字符串文字而不对其进行转义?
.
请考虑
