python - How to solve the issue of the conflict of anaconda and virtualenv -

i using virtualenv time , had installed anaconda. tried activate virtual environment using way of anaconda source activate helloworld. (indeed don't remember if command typed in). , environment had been activated. when tried run notebook, said libraries didn't exist if had installed them in environment. not until did realize had activated wrong environment. , close tab , cd hellowworld , did source bin/activate. late. got output prepending /home/lcc/anaconda3/envs/bin path , environment not activated expectedly. know how solve issue? thanks!

here full content of activate file under /hello/world:

it's not clear question expect "activate" do. activating virtualenv, or activating conda environment.

when install miniconda or anaconda, given option add path. if so, comes before virtualenv activate script. can rename 1 or other, or create alias virtualenv 1 calls absolute path activate script. can move anaconda it's appended rather prepended, virtualenv activate used rather conda 1 (barring absolute paths).

to append conda's path, in ~/.bashrc or ~/.bash_profile , change

export path=<anaconda path>:$path 

to

export path=$path:<anaconda path>
