最近，需要在linux系统下，使用pyinstaller生成py文件的可执行文件，但遇到一些报错，最后总算解决。
首先运行pyinstaller –onefile test.py，显示报错信息
OSError: Python library not found: libpython3.7.so.1.0, libpython3.7mu.so.1.0, libpython3.7m.so.1.0. This would mean your Python installation doesn’t come with proper library files. This usually happens by missing development package, or unsuitable build parameters of Python installation.

搜了搜，需要安装python-devel，运行yum install python-devel，结果显示找不到这个包。后来又搜了搜，是使用./configure –enable-shared重新编译python，编译后，make，make install安装好后，运行python3，又报错
python3: error while loading shared libraries: libpython3.7m.so.1.0: cannot open shared object file: No such file or directory

这时，
cd /etc/ld.so.conf.d
vi python3.conf
输入/usr/local/lib，然后:wq保存退出
运行ldconfig

之后在运行python3就没问题了
python3

运行pyinstaller也好了pyinstaller –onefile test.py
