is this so? When we find the installed Express directory, we find a lot less than the previously familiar express. What do we do? The speculation is that the Express version is updated, but we don't know how to play the new version. So I had to remove the currently installed express and reinstall the previous version to try it. Test OK.The commands used here areUninstall: NPM Uninstall-g ExpressInstall the specified version: NPM install-g [email protected]View version: Express-

. This parameter is useful and makes samba configuration more flexible. A samba server can simulate multiple servers with different configurations. For example, if you want PC1 (host name) to use its own configuration file when accessing the Samba Server, configure an smb name for PC1 under/etc/samba/host. conf. pc1 file, and then in smb. add: config file =/etc/samba/host/smb to conf. conf. % m. In this way, when PC1 requests to connect to the Samba Server, smb. conf. % m is replaced with smb. c
