How to uninstall package in Anaconda installed with pip

问题

The problem:

I have installed Anaconda:

conda -V
conda 4.4.7

Also I installed a lot of packages for it using python3 setup.py install. I used it for some packages created from setup.py files.

Now I want to uninstall one package.

What I tried:

pip uninstall packageName
pip3 uninstall packageName
conda uninstall packageName

It works for python: check pip list and pip3 list and there isn't such package.

Error:

But for conda I got this:

conda uninstall packageName
Solving environment: failed

PackagesNotFoundError: The following packages are missing from the target environment:
  - packageName

Let's check:

conda list
packageName

P.S. I found info that conda uninstall and conda remove doesn't work in this case. But what to do then?

P.S.S. Actually I changed real package name at packageName but if this information is important I will add it.

My info:

回答1:

You can use Jupyter Notebook to solve this problem :

open Jupyter Notebook
open a new notebook with the right kernel
type !pip uninstall -y [package] in a code cell
run the cell code

回答2:

If you installed the package using setup.py, then you will most likely have to delete the package files manually.

You'd find the Uninstalling setup.py install wiki useful. Unix instructions quoted below:

sudo python setup.py install --record files.txt
# inspect files.txt to make sure it looks ok. Then in bash:
tr '\n' '\0' < files.txt | xargs -0 sudo rm -f --

One has to be careful when using pip inside a conda environment, whether for installing and unistalling packages. What works for me is based on https://stackoverflow.com/a/43729857/1047213.

Install pip that is specific to the conda environment by running conda install pip inside the conda environment.
Specify the entire path of that specific pip while installing or uninstalling a package. Usually, you will find it inside the bin folder of the virtual environment (e.g., /anaconda/envs/venv_name/bin/). Thus, the following works for me: /anaconda/envs/venv_name/bin/pip install_or_uninstall package_name.
