bash 正在寻找丢失的 ' " ' ，意外的 EOF

Question

我有 bash 问题，它正在寻找丢失的字符，但我找不到它。也许还有其他问题？

每次打开终端时都会出现此错误：

bash：/home/chill/.bashrc：第 132 行：寻找匹配的“”时出现意外 EOF

.bashrc文件内容：

"我能找到的唯一缺失是在第 120 行，但如果我用"sudo补充它，那么 sudo 将停止工作。

我一定是遗漏了一些东西，或者只是不明白。有什么建议？

Answer 1

在ShellCheck 中粘贴代码揭示了问题：

120  export PATH="/home/chill/android-studio/bin
                  ^––SC1078 Did you forget to close this double quoted string?

121  export PATH="$HOME/.rbenv/bin:$PATH"
                  ^––SC1079 This is actually an end quote, but due to next char it looks suspect.

所以你需要在这一行添加一个结束双引号：

export PATH="/home/chill/android-studio/bin

变成这样：

export PATH="/home/chill/android-studio/bin"
                                           ^

Answer 2

问题出在您的第 120 行。您是对的，缺少 '"'，您应该将其添加到那里。

当您在第 120 行末尾添加 '"' 时，第 120 行会以不应该的方式更改您的 PATH 环境变量。它会覆盖 PATH 并且不关心 PATH 的先前值。正确的第 120 行将是:

export PATH="/home/chill/android-studio/bin:$PATH"

看一下其他类似的行，您会发现末尾总是有“:$PATH”。这意味着您只需将新目录添加到 $PATH 中现有的目录列表中。第 120 行只是用一个目录覆盖 PATH。最后加上 $PATH 你的 sudo 也可以工作。不仅仅是 bashrc 脚本。
