pip: force install ignoring dependencies

Question

Is there any way to force install a pip python package ignoring all it's dependencies that cannot be satisfied?

(I don't care how "wrong" it is to do so, I just need to do it, any logic and reasoning aside...)

Answer 1

pip has a --no-dependencies switch. You should use that.

For more information, run pip install -h , where you'll see this line:

--no-deps, --no-dependencies
                        Ignore package dependencies

Answer 2

Try the following:

pip install --no-deps <LIB_NAME>

or

pip install --no-dependencies <LIB_NAME>

or

pip install --no-deps -r requirements.txt

or

pip install --no-dependencies -r requirements.txt

Answer 3

When I were trying install librosa package with pip ( pip install librosa ), this error were appeared:

ERROR: Cannot uninstall 'llvmlite'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

I tried to remove llvmlite , but pip uninstall could not remove it. So, I used capability of ignore of pip by this code:

pip install librosa --ignore-installed llvmlite

Indeed, you can use this rule for ignoring a package you don't want to consider:

pip install {package you want to install} --ignore-installed {installed package you don't want to consider}
