怎么回事？谢谢。
答案1
sqlite并且sqlite3是同一程序的两个不同、不兼容的版本。
sqlite适用于 SQLite 数据库版本 2。sqlite3适用于 SQLite 数据库版本 3。 之所以有两个版本，是因为数据库格式在版本 2 和版本 3 之间发生了变化，所以这两种格式不兼容。
如果您安装了该sqlite3软件包，则需要使用该sqlite3命令。 如果您安装了该sqlite软件包，则需要使用该sqlite命令。
另外需要注意的是，二进制文件安装在/bin或中/usr/bin，而不是 中/var，后者通常用于程序数据。您还需要使用 命令which，它会根据您的 打印命令的位置$PATH。运行which sqlite3会返回/usr/bin/sqlite3。
