我在.bashrc文件中添加了scala,但当我关闭mac并重新打开它时,它找不到它
source ~/.bashrc
一切恢复正常。我想说,问题是整个文件,但问题是,我在那里有其他东西,以前工作得很好,但scala的问题一直存在。有人知道为什么会这样,并解释为什么我会遇到这个问题吗?这是我的.bashrc文件中的内容,它正确运行rvm和mysql,但不运行scala:
PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
export PATH="/usr/local/mysql/bin:$PATH"
export PATH="/Users/Zeroe/scala-2.9.1-1/bin:$PATH"
我通过将echo "${BASH_SOURCE[0]}"
添加到这些脚本中,得出了这个图。

您的shell可能是一个登录shell,在这种情况下,bash将按顺序读取各种配置文件:
/etc/profile
~/.bash_profile
~/.bash_login
~/.profile
通常从其中一个文件中获取~/.bashrc
,这样您也可以获得相同的登录shell配置。
这就是我的~/.profile
包含的内容:
# ~/.profile: executed by the command interpreter for login shells.
# This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login
# exists.
# see /usr/share/doc/bash/examples/startup-files for examples.
# the files are located in the bash-doc package.
# the default umask is set in /etc/profile; for setting the umask
# for ssh logins, install and configure the libpam-umask package.
#umask 022
# if running bash
if [ -n "$BASH_VERSION" ]; then
# include .bashrc if it exists
if [ -f "$HOME/.bashrc" ]; then
. "$HOME/.bashrc"
fi
fi
# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
PATH="$HOME/bin:$PATH"
