当将 DYLD_LIBRARY_PATH 添加到 bashrc 时，Anaconda 停止工作

我在 macOS Mojave 10.14.5 上使用 Anaconda Navigator 版本 1.9.7。我发现当我将以下命令添加到 .bashrc 时，大多数 anaconda-navigator、pip 等命令都停止工作。

export DYLD_LIBRARY_PATH=/opt/x11/lib/:/opt/local/lib/libgcc/:/opt/local/lib/gcc47/:$DYLD_LIBRARY_PATH

对于 pip 命令，我收到以下错误：

该文件/opt/x11/lib//libPng.dylib确实存在。

答案1

DYLD_FALLBACK_LIBRARY_PATH我发现如果我使用而不是DYLD_LIBRARY_PATH遵循， 错误就会消失这里的讨论
