source activate 如何自动更新环境变量
问题: 运行
source activate env_name之后再运行python -V仍然是旧环境中的 python-
解决办法：
Locate the directory for the conda environment in your terminal window by running in the terminal
echo $CONDA_PREFIX.-
Enter that directory and create these subdirectories and files:
cd $CONDA_PREFIX mkdir -p ./etc/conda/activate.d mkdir -p ./etc/conda/deactivate.d touch ./etc/conda/activate.d/env_vars.sh touch ./etc/conda/deactivate.d/env_vars.sh -
Edit
./etc/conda/activate.d/env_vars.shas follows:#!/bin/sh export MY_KEY='secret-key-value' export MY_FILE=/path/to/my/file/ -
Edit
./etc/conda/deactivate.d/env_vars.shas follows:#!/bin/sh unset MY_KEY unset MY_FILE
When you run conda activate analytics, the environment variables MY_KEY and MY_FILE are set to the values you wrote into the file. When you run conda deactivate, those variables are erased.
