Emacs 24.3 on OS X ansi-term 没有颜色

Question

我使用自制软件安装了 Emacs 24.3（使用 --cocoa 和 --srgb 安装）。每当我启动 emacs.app，然后启动 ansi-term 时，它就没有颜色。但是，当我执行emacs -q 并启动应用程序时，ansi-term 有颜色。

所以我想我的init.el 文件中可能有什么问题。我注释掉了所有内容，仍然 ansi-term 不适用于颜色。

这一切中最奇怪的部分是，当我启用init.el 中的所有内容时，我执行emacs -nw，然后在那里执行 ansi-term（我知道，令人费解，但我正在尝试测试这个东西）它适用于所有主题和所有运行的附加组件。这太奇怪了，我什至不知道从哪里开始。

似乎在应用程序运行时，它没有使用我的bash_profile 中的设置。我为什么这么说？因为当 ansi-term 运行良好（使用emacs -nw）时，它说：bash: _powerline_prompt: command not found 这意味着它正在尝试加载我为终端安装的电力线，但不知道如何处理它。我只是禁用了电力线，看看它是否是罪魁祸首，即使这样也不能解决问题。

但是，当 ansi-term 没有颜色时，它不会喷出那条线。

那么有人知道到底发生了什么吗？ （自制 emacs.app 是否使用另一个 .bash_profile 可能？）

这是我的init.el 禁用了外部包，所以其中的所有内容都是由 emacs 和包自动设置的：

Answer 1

似乎在应用程序运行时，它没有使用中的设置 我的 bash_profile

我相信这是问题所在，似乎 emacs 在作为应用程序启动时（即不是从 shell 启动）并没有选择正确的 PATH。这解释了为什么在从 shell 启动 emacs 时ansi-term 有颜色（我合理假设您从 shell 运行 emacs -q 和 emacs -nw :)）。

请参阅this 了解可能的解决方案。您可能会发现this 也很有帮助。

Answer 2

这可能是一个 hack，但我通过将我的 .bash_profile 复制到 .bashrc 解决了这个问题（所以我同时拥有 .bash_profile 和 .bashrc）。

如果我从 Terminal.app 启动 Emacs.app，它会读取我的 .bash_profile。当我通过单击 Applications 文件夹中的 Emacs 图标启动它时，它会读取我的.bashrc。我不知道这是否是正常行为，但出于我的目的，它运行完美，因为我已从 .bashrc 中删除了电力线，因此 ansi-term 不会一直抛出错误。

总而言之，这是一个非常简单的解决方案，我希望其他人可以从中受益。
