每当我在 tmux 或 screen 会话中使用 Tensorflow（一个 Python 库）时，我都必须手动更改环境变量。具体来说，我必须输入export PATH blah blah blah和export LD_LIBRARY_PATH blah blah blah。通常（在 tmux 和 screen 之外）我不需要这样做，因为我的 .bashrc 包含正是这些行。
奇怪的是，由于某种原因，source ~/.bashrc从 tmux 或 screen 运行不会更新路径变量。我也尝试添加source ~/.bashrc到我的.profile.所以，我的问题是，我需要做什么才能让 tmux 和 screen 自动运行我的两条导出线？
编辑：运行后set -x; source ~/.bashrc，打印输出的末尾显示：
