pyinstaller错误:OSError:找不到Python库:libpython3.4mu.so.1.0,libpython3.4m.so.1.0,libpython3.4.so.1.0

Question

我在Centos7上使用Python 3.4.4.

我在我的本地机器上创建了一个使用qt模块的python程序.该程序在我的本地计算机上正常运行.我现在正在尝试使用pyinstaller创建可执行文件.我正在使用命令:

pyinstaller main.py

我得到以下输出:

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.

* On Debian/Ubuntu, you would need to install Python development packages
  * apt-get install python3-dev
  * apt-get install python-dev
* If you're building Python by yourself, please rebuild your Python with `--enable-shared` (or, `--enable-framework` on Darwin)

有谁知道这个问题是什么？只是说我安装了python3-devel和python-devel(相对于打印输出结尾的建议.)谢谢

Answer 1

对于像您这样的 Linux 系统CentOS，请尝试使用以下命令重建 python 以生成共享库：

env PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install 3.4.4

正如pyenv官方文档中所说

Answer 2

你必须为你的 python 版本安装 python-dev

例如：

Debian/Ubuntu - Python 2.7 ---> python2.7-dev

CentOs/RedHat - Python 3.4 ---> python34-devel

CentOs/RedHat - Python 2.7 ---> python27-devel

然而，这些错误之一可能令人费解： IOError("Python library not found!") PyInstaller 需要捆绑 Python 库，它是 Python 解释器的主要部分，链接为动态加载库。此文件的名称和位置因使用的平台而异。默认情况下，某些 Python 安装不包含动态 Python 库（静态链接的库可能存在但无法使用）。您可能需要安装某种开发包。或者，该库可能存在但不在 PyInstaller 正在搜索的文件夹中。

PyInstaller查找python库的地方在不同的操作系统中是不一样的，但是/lib和/usr/lib在大多数系统中都是被勾选的。如果您不能将 python 库放在那里，请尝试在 Linux 中的环境变量 LD_LIBRARY_PATH 或 OS X 中的 DYLD_LIBRARY_PATH 中设置正确的路径。
