I usually just lurk and read on this list. I don't reply since there's usually more competent people that regularly post helpful answers. (I lurk to learn from them!)

If no one's replied yet, I'll give it my 2 cents ...

Without being a pip expert, I see from 'pip install -h' that you can specify where you want the package to be installed.

Install Options:
  -r, --requirement <file>    Install from the given requirements file. This option can be used multiple times.
  -c, --constraint <file>     Constrain versions using the given constraints file. This option can be used multiple
                              times.
  --no-deps                   Don't install package dependencies.
  --pre                       Include pre-release and development versions. By default, pip only finds stable
                              versions.
  -e, --editable <path/url>   Install a project in editable mode (i.e. setuptools "develop mode") from a local project
                              path or a VCS url.
  -t, --target <dir>          Install packages into <dir>. By default this will not replace existing files/folders in
                              <dir>. Use --upgrade to replace existing packages in <dir> with new versions.
  --user                      Install to the Python user install directory for your platform. Typically ~/.local/, or
                              %APPDATA%\Python on Windows. (See the Python documentation for site.USER_BASE for full
                              details.)
  --root <dir>                Install everything relative to this alternate root directory.
  --prefix <dir>              Installation prefix where lib, bin and other top-level folders are placed
  -b, --build <dir>           Directory to unpack packages into and build in. Note that an initial build still takes
                              place in a temporary directory. The location of temporary directories can be controlled
                              by setting the TMPDIR environment variable (TEMP on Windows) appropriately. When passed,
                              build directories are not cleaned in case of failures.
  --src <dir>                 Directory to check out editable projects into. The default in a virtualenv is "<venv
                              path>/src". The default for global installs is "<current dir>/src".
  -U, --upgrade               Upgrade all specified packages to the newest available version. The handling of
                              dependencies depends on the upgrade-strategy used.
  --upgrade-strategy <upgrade_strategy>
                              Determines how dependency upgrading should be handled [default: only-if-needed]. "eager"
                              - dependencies are upgraded regardless of whether the currently installed version
                              satisfies the requirements of the upgraded package(s). "only-if-needed" -  are upgraded
                              only when they do not satisfy the requirements of the upgraded package(s).
  --force-reinstall           Reinstall all packages even if they are already up-to-date.
  -I, --ignore-installed      Ignore the installed packages (reinstalling instead).
  --ignore-requires-python    Ignore the Requires-Python information.
  --no-build-isolation        Disable isolation when building a modern source distribution. Build dependencies
                              specified by PEP 518 must be already installed if this option is used.
  --install-option <options>  Extra arguments to be supplied to the setup.py install command (use like --install-
                              option="--install-scripts=/usr/local/bin"). Use multiple --install-option options to
                              pass multiple options to setup.py install. If you are using an option with a directory
                              path, be sure to use absolute path.
  --global-option <options>   Extra global options to be supplied to the setup.py call before the install command.
  --compile                   Compile Python source files to bytecode
  --no-compile                Do not compile Python source files to bytecode
  --no-warn-script-location   Do not warn when installing scripts outside PATH
  --no-warn-conflicts         Do not warn about broken dependencies
  --no-binary <format_control>
                              Do not use binary packages. Can be supplied multiple times, and each time adds to the
                              existing value. Accepts either :all: to disable all binary packages, :none: to empty the
                              set, or one or more package names with commas between them. Note that some packages are
                              tricky to compile and may fail to install when this option is used on them.
  --only-binary <format_control>
                              Do not use source packages. Can be supplied multiple times, and each time adds to the
                              existing value. Accepts either :all: to disable all source packages, :none: to empty the
                              set, or one or more package names with commas between them. Packages without binary
                              distributions will fail to install when this option is used on them.
  --no-clean                  Don't clean up build directories).
  --require-hashes            Require a hash to check each requirement against, for repeatable installs. This option
                              is implied when any package in a requirements file has a --hash option.
  --progress-bar <progress_bar>
                              Specify type of progress to be displayed [off|on|ascii|pretty|emoji] (default: on)

I'm thinking the the --target option may be the solution.

Again, just my 2 cents.
