Pyinstaller不能识别为内部或外部命令

Question

我试图在cmd中使用pyinstaller，但收到错误：

C:\Users\username>pyinstaller
'pyinstaller' is not recognized as an internal or external command,
operable program or batch file.

C:\Users\username>

当我在python的Scripts文件夹中使用此命令时，它可以工作：

C:\Users\username\AppData\Local\Programs\Python\Python36-32\Scripts>pyinstaller
usage: pyinstaller [-h] [-v] [-D] [-F] [--specpath DIR] [-n NAME]
                   [--add-data <SRC;DEST or SRC:DEST>]
                   [--add-binary <SRC;DEST or SRC:DEST>] [-p DIR]

                   [--upx-dir UPX_DIR] [-a] [--clean] [--log-level LEVEL]
                   [--upx UPX]
                   scriptname [scriptname ...]
pyinstaller: error: the following arguments are required: scriptname

C:\Users\username\AppData\Local\Programs\Python\Python36-32\Scripts>

如何解决这个问题？

Answer 1

必须修改路径环境以包含C:\Users\username\AppData\Local\Programs\Python\Python36-32\Scripts> 如果你不知道怎么做 看here
祝你好运

Answer 2

对于Python 3.7，必须将AppData/Roaming中的Scripts文件夹（%AppData%）添加到PATH变量中。

C:\Users\%USERNAME%AppData\Roaming\Python\Python37\Scripts
