在（pip）安装后使用pyinstaller时出现无法识别的命令错误

Question

当试图找到一种将python文件“捆绑”到.exe中的好方法时，我遇到了pyinstaller。我查了一下如何使用它的指南，发现了这个guide。我只是使用pip install pyinstaller安装了pyinstaller，它似乎安装得很好，但当试图在控制台中使用pyinstaller时，它出现了一个错误，说'pyinstaller' is not recognized as an internal or external command, operable program or batch file.我甚至试图将文件所在的目录更改为，但仍然出现了相同的错误。当尝试通过pip再次安装时（以防发生错误），我收到以下消息：

Answer 1

尝试在命令pyinstaller前面加上python -m：

python -m PyInstaller yourscript.py

如果不起作用，请尝试使用python3 -m或py -m：

python3 -m PyInstaller yourscript.py
py -m PyInstaller yourscript.py

Answer 2

您可以通过在python3前面加前缀来执行pyinstaller

python3 -m pyinstaller file.py

如果没有前缀，则应遵循以下方法

在Windows中，pyinstaller可执行文件，位于

C:\Users\USER_NAME\AppData\Roaming\Python\Python37\Scripts
                             (or)
C:\Program Files\Python37\Scripts

并复制pyinstaller executable路径并将其添加到Windows System Environment Variables

1. 单击开始菜单中的搜索并搜索Edit System Environment Variables

2. 点击底部的Environment variables。 单击Path并单击edit

3. 单击New并在path部分添加复制的pyinstaller executable路径 然后单击OK

4. 现在检查CMD中的pyinstaller
