【问题描述】：
我很久以前就安装了 pacman 的 QT5。
qmake -v
QMake version 3.1
Using Qt version 5.15.2 in /usr/lib
我想安装 QT 5.5.1，所以我下载了 qt-everywhere-opensource-src-5.5.1.7z 并按照自述文件进行操作。 这是最终结果：
make[3]: *** [Makefile:21908: .obj/qsslcertificate_openssl.o] Error 1
make[3]: Leaving directory '/home/chippy/Downloads/qt-everywhere-opensource-src-5.5.1/qtbase/src/network'
make[2]: *** [Makefile:192: sub-network-make_first] Error 2
make[2]: Leaving directory '/home/chippy/Downloads/qt-everywhere-opensource-src-5.5.1/qtbase/src'
make[1]: *** [Makefile:46: sub-src-make_first] Error 2
make[1]: Leaving directory '/home/chippy/Downloads/qt-everywhere-opensource-src-5.5.1/qtbase'
make: *** [Makefile:73: module-qtbase-make_first] Error 2
然后我下载了 qt-opensource-linux-x64-5.5.1.run 在 shell 上运行：
$ ./qt-opensource-linux-x64-5.5.1.run

我无法理解错误，我不知道这是否是解决问题的正确方法。
【问题讨论】：
-
这个问题最好在Unix Stack Exchange问，我相信你可能会找到一个已经在那里问过的问题
-
删除之前的qt，然后安装一个新的。
