How to evaluate all code blocks when exporting in emacs org-mode

Question

I have an org-mode document with many different R source code blocks. Whenever I hit Cc Ce and export to PDF or HTML I get a different prompt asking to evaluate each code block. This wasn't a big deal, but now I have to type yes 20+ times. Is there an option to automatically evaluate all the code blocks?

Answer 1

我想这就是你想要的：

(setq org-confirm-babel-evaluate nil)

Answer 2

将以下行放在文件的顶部，这样一旦打开它就会被问到一次，而更安全的非评估默认值对于其他文件仍然是正确的

# -*- org-confirm-babel-evaluate: nil -*-
