我正在尝试在厨师中使用python解释器。以下是我没有用的天真尝试。在python中完成下面的正确方法是什么?
script "install_something" do
interpreter "python"
user "root"
cwd "/tmp"
code <<-EOH
import boto
f = open('test.txt','r')
f.write('adfadf')
f.close()
EOH
not_if {File.exists?("/tmp/test.txt")}
end

答案 0 :(得分:9)
的内容
code <<-EOH
import boto
f = open('test.txt','r')
f.write('adfadf')
f.close()
EOH
逐字传递给解释器,也就是说包括前导缩进。因为缩进形成了python语法的一部分,所以您的脚本(在<<-EOH
/ EOH
之间)不是有效的python。
此案例中的解决方案是删除<<-EOH
/ EOH
块中的缩进。
