我使用的是Ruby 2.2.2。当我class MainServer
{
private:
SOCKET soo;
bool init;
public:
MainServer()
: soo(INVALID_SOCKET), init(false)
{
WSADATA wsa;
printf("\nInitialising Winsock...");
int err = WSAStartup(MAKEWORD(2, 2), &wsa);
if (err != 0)
{
printf("Failed. Error Code : %d\n", err);
MessageBox(NULL, L"WSAStartup Failed", L"Failed", NULL);
}
else
{
init = true;
printf("Initialized.\n");
//MessageBox(NULL, L"Initialized", L"Simple Message", NULL);
}
}
~MainServer()
{
close_server_socket();
if (init)
WSACleanup();
}
SOCKET socket_control_mob()
{
struct sockaddr_in server = {0};
close_server_socket();
//Create a socket
soo = socket(AF_INET, SOCK_STREAM, 0);
if (soo == INVALID_SOCKET)
{
printf("Could not create socket. Error Code : %d\n", WSAGetLastError());
MessageBox(NULL, L"Socket Not Created", L"socket Failed", NULL);
return INVALID_SOCKET;
}
printf("Socket created.\n");
//Prepare the sockaddr_in structure
server.sin_family = AF_INET;
server.sin_addr.s_addr = INADDR_ANY;
server.sin_port = htons(8890);
//Bind
if (bind(soo, (struct sockaddr *)&server, sizeof(server)) == SOCKET_ERROR)
{
printf("Bind failed. Error Code : %d", WSAGetLastError());
MessageBox(NULL, L"Binding Error", L"bind Failed", NULL);
close_server_socket();
return INVALID_SOCKET;
}
printf("Bind done.\n");
//MessageBox(NULL, L"Bind Done", L"Simple Message", NULL);
return soo;
}
void server_close_socket()
{
if (soo != INVALID_SOCKET)
{
closesocket(soo);
soo = INVALID_SOCKET;
}
}
};
时，我得到了一个名为bundle --path vendor/bundle的文件夹。
My Gemfile指定Ruby 2.2.2。我的vendor/bundle/ruby/2.2.0指定2.2.2。
当我.ruby-version时，我得到rvm list。当我=> ruby-2.2.2 [ x86_64 ]时，我得到ruby -v。我甚至卸载了Ruby 2.2.0，当我ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin14]时，我仍然得到2.2.0文件夹。
为什么使用Ruby 2.2.0，如何才能使用2.2.2？
答案 0 :(得分：3)
我之前也见过这个，我想这可能是你问题的答案：
vendor/bundle and ruby version
您可以在rails控制台中快速验证：
> Loading development environment (Rails 4.2.4)
> 2.1.2 :001 > RbConfig::CONFIG['ruby_version'] => "2.1.0"
