安装pyinstaller时出现问题

Question

我尝试了pip安装，收到了以下消息：

Requirement already satisfied: pyinstaller in c:\users\sinwe\appdata\local\programs\python\python39\lib\site-packages (4.5.1)
Requirement already satisfied: altgraph in c:\users\sinwe\appdata\local\programs\python\python39\lib\site-packages (from pyinstaller) (0.17)
Requirement already satisfied: pyinstaller-hooks-contrib>=2020.6 in c:\users\sinwe\appdata\local\programs\python\python39\lib\site-packages (from pyinstaller) (2021.2)
Requirement already satisfied: pywin32-ctypes>=0.2.0 in c:\users\sinwe\appdata\local\programs\python\python39\lib\site-packages (from pyinstaller) (0.2.0)
Requirement already satisfied: pefile>=2017.8.1 in c:\users\sinwe\appdata\local\programs\python\python39\lib\site-packages (from pyinstaller) (2021.5.24)
Requirement already satisfied: setuptools in c:\users\sinwe\appdata\local\programs\python\python39\lib\site-packages (from pyinstaller) (49.2.1)
Requirement already satisfied: future in c:\users\sinwe\appdata\local\programs\python\python39\lib\site-packages (from pefile>=2017.8.1->pyinstaller) (0.18.2)

然后我使用setup.py进行了安装

要检查是否已安装，请在cmd中：

pyinstaller --version

我收到了这个：

Traceback (most recent call last):
  File "C:\Users\sinwe\AppData\Local\Programs\Python\Python39\Scripts\pyinstaller-script.py", line 33, in <module>
    sys.exit(load_entry_point('pyinstaller==4.5.1', 'console_scripts', 'pyinstaller')())
  File "C:\Users\sinwe\AppData\Local\Programs\Python\Python39\Scripts\pyinstaller-script.py", line 25, in importlib_load_entry_point
    return next(matches).load()
StopIteration
