Conda Environment Settings如何用conda创建环境并配置环境变量

Create a new environment
To create a new conda environment, use the following command:
1
conda create --name myenv
Replace myenv with the name you want for your environment. You can also specify the Python version:
1
conda create --name myenv python=3.8
Alternatively, you can create an environment at a specific path using the -p option:
1
conda create -p /path/to/myenv
Replace /path/to/myenv with your desired path. You can also specify the Python version:
1
conda create -p /path/to/myenv python=3.8
Set environment variables for a specific environment
To set environment variables for a specific conda environment, use the conda env config vars set command. For example:
1
conda env config vars set MY_VAR=value
Replace MY_VAR and value with your desired variable name and value.
Activate the environment to apply the changes:
1
conda activate myenv
To view the environment variables set for the active environment, use:
1
conda env config vars list
To unset an environment variable, use:
1
conda env config vars unset MY_VAR
Replace MY_VAR with the name of the variable you want to unset.
For more details, refer to the official conda documentation.
Example: Setting PYTHONPATH
To set the PYTHONPATH environment variable for a specific conda environment, use the following command:
1
conda env config vars set PYTHONPATH=/path/to/your/modules
Replace /path/to/your/modules with the path you want to add to PYTHONPATH.
Activate the environment to apply the changes:
1
conda activate myenv
To verify that PYTHONPATH has been set, you can list the environment variables:
1
conda env config vars list
Delete an environment
To delete a conda environment, use the conda remove command with the --name option. For example:
1
conda remove --name myenv --all
Replace myenv with the name of the environment you want to delete. The --all flag ensures that all packages in the environment are removed.
Alternatively, if you created the environment at a specific path, use the -p option:
1
conda remove -p /path/to/myenv --all
Replace /path/to/myenv with the path to the environment you want to delete.
For more details, refer to the official conda documentation.
