在我的 Conda 环境中安装 pip 包的位置？

Question

As I understand it, if I use pip install ___, that package will go to my global version of python. If I change directory to the within my Conda environment then that package will be isolated within the environment. Is this correct?

I have searched to try and find where to put the pip packages (within my Conda environment). It used to be that you would install the pip packages in /Anaconda3/envs/venv_name/bin/ . It appears the bin folder is now located within the Library folder, like this: /Anaconda3/envs/venv_name/Library/bin . Is the bin folder still the recommended place to put the packages installed by pip?

In other words should I be placing the pip installed packages here: /Anaconda3/envs/venv_name/Library/bin ?

Answer 1

No Specification Needed

Fortunately, one doesn't have to manually designate where to install the packages. Instead, if one uses the pip associated with the environment, it will install them to the site-packages directory of env's python .

Example

 > conda activate venv_name
 
 # check that you are using the right pip
 > which pip
 /Anaconda3/envs/venv_name/bin/pip  # should be something like this

 > pip install <package name>

This will install packages into /Anaconda3/envs/venv_name/lib/python3.7/site-packages/ , or whatever Python version you have install for the env.

Caution: Mixing PyPI and Conda Packages

Be aware that (as @WilliamDIrons pointed out), it is usually preferable to use conda install -n venv_name <package name> instead of pip . The common practice is to only use pip in a Conda env when the package is not available through a Conda repository. It is strongly recommended to read and follow the best practices found in the " Using pip in an environment " documentation.
