Conda 仅针对 env 设置 LD_LIBRARY_PATH

Question

我安装了 miniconda3，我在其中创建了一个名为 py35 的虚拟环境。我有一些我只想在此环境中使用的库。因此他们在

 /.../miniconda3/envs/py35/libs

但是在环境中找不到它们，因为 LD_LIBRARY_PATH 不包含所述文件夹。我现在想设置 LD_LIBRARY_PATH 仅当我在虚拟环境中时才包含 /lib。

我正在考虑修改 miniconda 用于启动环境的激活脚本，但不太确定这是否是标准做法，或者是否有更简单的方法来实现此目的。

Answer 1

您可以在通过编辑 activate.d/env_vars.sh 脚本激活环境时设置环境变量。看这里：https://conda.io/docs/user-guide/tasks/manage-environments.html#macos-and-linux

link 的关键部分是：

Locate the directory for the conda environment in your Terminal window, such as /home/jsmith/anaconda3/envs/analytics.
Enter that directory and create these subdirectories and files:
cd /home/jsmith/anaconda3/envs/analytics
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.sh as follows:
#!/bin/sh

export MY_KEY='secret-key-value'
export MY_FILE=/path/to/my/file/
Edit ./etc/conda/deactivate.d/env_vars.sh as 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.

我只是想补充一点，您可以在 activate.d/env_vars.sh 中声明 2 个变量，这样可以更轻松地将变量重置为 pre-activation 状态：

export OLD_LD_LIBRARY_PATH=${LD_LIBRARY_PATH}
export LD_LIBRARY_PATH=/your/path:${LD_LIBRARY_PATH}

然后在deactivate.d/env_vars.sh:

export LD_LIBRARY_PATH=${OLD_LD_LIBRARY_PATH}
unset OLD_LD_LIBRARY_PATH

Conda 仅针对 env 设置 LD_LIBRARY_PATH

Conda set LD_LIBRARY_PATH for env only

python

virtualenv

anaconda
