我想在.bash_profile
中设置以下内容bash_profile_content = %Q(
export EDITOR=vi
export ENV=#{role}
export PATH=$PATH:/usr/local/bin
export PS1="${debian_chroot:+($debian_chroot)}\u@\h:\w [$ENV]\$ "
)
file '/home/me/.bash_profile' do
cotent bash_profile_conent
end
Chef抛出此错误:
==> Server-002: [2015-10-07T03:02:23+00:00] ERROR: Exception handlers complete
==> Server-002: Chef Client failed. 0 resources updated in 322.419863736 seconds

显然,厨师认为@
字符是用于unicode逃脱的。
我想按原样使用@
。我该如何解决这个错误?
答案 0 :(得分:3)
这不是真正的问题,\u
是。例如:
irb > "\u@"
SyntaxError: (irb):1: invalid Unicode escape
"\u@"
^
但:
irb > "\u0611"
=> "ؑ"
请记住,%Q(...)
的行为类似于双引号字符串,因此适用所有常用的转义符(例如Unicode的\u
)。添加更多反斜杠应该解决问题:
bash_profile_content = %Q(
export EDITOR=vi
export ENV=#{role}
export PATH=$PATH:/usr/local/bin
export PS1="${debian_chroot:+($debian_chroot)}\\u@\\h:\\w [$ENV]\\$ "
)
