找不到符号：_lua_objlen
Symbol not found: _lua_objlen
我正在使用 lua-cjson
package.path = package.path .. ";../?.lua"
local json = require('cjson')
我得到：
lua: error loading module 'cjson' from file '/usr/local/lib/lua/5.3/cjson.so':
dlopen(/usr/local/lib/lua/5.3/cjson.so, 6): Symbol not found: _lua_objlen
Referenced from: /usr/local/lib/lua/5.3/cjson.so

stack traceback:

有什么想法吗？使用 lua 5.3
似乎刚刚在 github 上针对这个问题打开了一个问题：https://github.com/mpx/lua-cjson/issues/56。对于它的价值，这是我在 github:
上发布的解决方法
我在 alpine linux 上看到与 lua-cjson 2.1.0.6-1 版相同的问题，我目前正在通过明确指定 2.1 版来解决这个问题。 0-1.
降级到 2.1.0-1 如@James Penick
