根据提供的引用内容,'adds2.xlsx' 文件不存在的错误是由于在尝试打开该文件时,Excel无法找到该文件或目录引起的。
要解决这个问题,有几个可能的解决方法:
1. 确保你输入的文件名和路径是正确的。检查是否拼写错误或者文件是否在指定的目录中。
2. 检查文件是否存在。你可以手动在文件资源管理器中查找文件或者使用命令行工具来确认文件是否存在。
3. 如果你使用的是自动化工具来打开文件,可以在代码中添加错误处理机制。在TRY...CATCH...ENDTRY块中捕获错误,并提供有关错误的详细信息。
总之,要解决"No such file or directory: 'adds2.xlsx'"错误,请确保文件名和路径正确,并检查文件是否存在。如果问题仍然存在,可能需要进一步检查文件系统或程序逻辑。

error while loading shared libraries: libncurses.so.5
This error typically occurs when a program or package depends on the libncurses.so.5 library, but it is not installed or is not in the expected location.
To resolve this issue, you can try the following steps:
1. Check if the library is installed on your system by running the following command:
```bash
sudo ldconfig -p | grep libncurses.so.5
```
If the library is not found, you may need to install it. On Ubuntu or Debian-based systems, you can do this with the following command:
```bash
sudo apt-get install libncurses5
```
2. If the library is installed but not in the default location, you can create a symbolic link to it. For example, if the library is located in /usr/local/lib, you can create a symbolic link to it with the following command:
```bash
sudo ln -s /usr/local/lib/libncurses.so.5 /usr/lib/libncurses.so.5
```
This command creates a symbolic link from /usr/lib/libncurses.so.5 to /usr/local/lib/libncurses.so.5.
3. If none of the above steps work, you may need to update your LD_LIBRARY_PATH environment variable to include the directory where the libncurses.so.5 library is located. For example, if the library is located in /usr/local/lib, you can add the following line to your .bashrc file:
```bash
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
```
This command adds /usr/local/lib to the beginning of the LD_LIBRARY_PATH variable, so that the system looks for libraries in that directory before looking in the default locations.
After performing any of these steps, try running the program again to see if the error has been resolved.
解释这段代码 type Person struct { Name string } const luaPersonTypeName = "person" // Registers my person type to given L. func registerPersonType(L *lua.LState) { mt := L.NewTypeMetatable(luaPersonTypeName) L.SetGlobal("person", mt) // static attributes L.SetField(mt, "new", L.NewFunction(newPerson)) // methods L.SetField(mt, "__index", L.SetFuncs(L.NewTable(), personMethods)) } // Constructor func newPerson(L *lua.LState) int { person := &Person{L.CheckString(1)} ud := L.NewUserData() ud.Value = person L.SetMetatable(ud, L.GetTypeMetatable(luaPersonTypeName)) L.Push(ud) return 1 } // Checks whether the first lua argument is a *LUserData with *Person and returns this *Person. func checkPerson(L *lua.LState) *Person { ud := L.CheckUserData(1) if v, ok := ud.Value.(*Person); ok { return v } L.ArgError(1, "person expected") return nil } var personMethods = map[string]lua.LGFunction{ "name": personGetSetName, } // Getter and setter for the Person#Name func personGetSetName(L *lua.LState) int { p := checkPerson(L) if L.GetTop() == 2 { p.Name = L.CheckString(2) return 0 } L.Push(lua.LString(p.Name)) return 1 } func main() { L := lua.NewState() defer L.Close() registerPersonType(L) if err := L.DoString(` p = person.new("Steeve") print(p:name()) -- "Steeve" p:name("Alice") print(p:name()) -- "Alice" `); err != nil { panic(err) } }
This code defines a Person struct with a single field "Name". It also defines a constant string "luaPersonTypeName" with the value "person". The code then defines a function "registerPersonType", which registers the "Person" type with a Lua state. This function sets up a metatable for the "person" type, and adds a "new" function to create a new instance of a Person object. It also sets up a getter and a setter for the "Name" field of the Person object.
The "newPerson" function is the constructor for a new Person object. It takes a Lua string argument for the Person's name, creates a new Person object with that name, and returns a Lua user data object that contains a pointer to the Person object.
The "checkPerson" function checks if a given Lua argument is a user data object containing a pointer to a Person object. If the argument is not a user data object or if it does not contain a pointer to a Person object, it raises an error and returns nil.
Finally, the "main" function creates a new Lua state, registers the Person type with the state, and executes a Lua script that creates a new Person object, sets and gets its name, and prints the name.
