E: Unable to locate package Kdevelop-dev这是一个小伙伴安装软件包时出现的问题其实LZ通过sudo apt-get install name安装软件的时候也会经常不记得一些依赖项的具体名字毕竟脑容量有限只能记得关键词下面就以Kdevelop为例。sudo apt-cache search Kdevelop //以下为输出 c-cpp-reference - C and C programming reference kdev-python - KDevelop Python Plugin kdevelop - integrated development environment for KDE kdevelop-data - data files for the KDevelop IDE kdevelop-dbg - debugging symbols for KDevelop kdevelop-dev - development files for the KDevelop IDE kdevelop-l10n - localization files for the KDevelop IDE kdevelop-pg-qt - LL(1) parser generator based on Qt kdevelop-php - PHP plugin for KDevelop kdevelop-php-dbg - debugging symbols for the KDevelop PHP plugin kdevelop-php-docs - PHP documentation plugin for KDevelop kdevelop-php-docs-l10n - localization files for KDevelop PHP documentation plugin kdevelop-php-l10n - localization files for KDevelop PHP plugin kdevplatform-dbg - debugging symbols for the KDevelop platform kdevplatform-dev - development files for the KDevelop platform kdevplatform-l10n - language package for the KDevelop platform kdevplatform7-libs - shared libraries for the KDevelop platform libkomparediff2-4 - Library to compare files and strings libkomparediff2-dev - Library to compare files and strings - development files libsublime-dev - development files for the sublime user interface library libsublime7 - User interface library qdevelop - A development environment entirely dedicated to Qt4可以对照自己的需求进行安装了♪(∇*)按照上面输出显示sudo apt-get install Kdevelop可能是ubuntu内核更新包名也会经常改变如果遇到这种sudo apt-get update后发现还是没有找到对应的包名那就使用sudo apt-cache search keyword是不是一个比较有用的小技巧呢O(∩_∩)O哈哈~
