首先我要说的是，我配置了一个 conky 文件并使其工作，但是当我添加 lua rings 时，它无需重新启动即可运行，但是一旦我重新启动，rings 就不会启动，我收到标题中的错误消息，这是我的 conky 脚本

Clock Rings by Linux Mint (2011) reEdited by despot77
This script draws percentage meters as rings, and also draws clock hands if you want! It is fully customisable; all options are described in the script. This script is based off a combination of my clock.lua script and my rings.lua script.
IMPORTANT: if you are using the 'cpu' function, it will cause a segmentation fault if it tries to draw a ring straight away. The if statement on line 145 uses a delay to make sure that this doesn't happen. It calculates the length of the delay by the number of updates since Conky started. Generally, a value of 5s is long enough, so if you update Conky every 1s, use update_num>5 in that if statement (the default). If you only update Conky every 2s, you should change it to update_num>3; conversely if you update Conky every 0.5s, you should use update_num>10. ALSO, if you change your Conky, is it best to use "killall conky; conky" to update it, otherwise the update_num will not be reset and you will get an error.
To call this script in Conky, use the following (assuming that you save this script to ~/scripts/rings.lua):
lua_load ~/scripts/clock_rings.lua

请帮忙，这是哪里出了问题？
答案1
我在 16.04 中遇到了同样的问题。我用 解决了sudo apt install conky-all -y。
希望它对你有用！
答案2
在函数conky_clock_rings()后面添加以下代码value=tonumber(str)
if not value then
value=0
end
答案3
您可以通过将以下行添加到您的 lua 脚本来解决您的问题：
str=string.format('${%s %s}',pt['name'],pt['arg'])
if str=='${time %I.%M}' then
str=conky_parse('${time %I}')+(conky_parse('${time %M}')/60)
elseif str=='${time %M.%S}' then
str=conky_parse('${time %M}')+(conky_parse('${time %S}')/60)
else
str=conky_parse(str)
end
value=tonumber(str)
if ( value == nil ) then value = 0 end
pct=value/pt['max']
这是我第一次使用 lua，但我解决了我的问题：
