python - 关于pyinstaller的路径问题

Question

我运行的是 Windows 7 和 Python 3.7(32 位)。我正在尝试使用命令提示符来安装 pyinstaller，但遇到了我可以解决的问题。

我让它短暂工作，直到我决定更新 pyinstaller 并且失败了。在那之后，一切都乱了套。作为实习生，我花了几乎一整天的工作日试图找出问题所在，但感觉自己束手无策。我知道这是我在数小时的寻找解决方案的过程中经常被问到的问题，但我真的很挣扎。最令人沮丧的部分是我可以运行 pip，但即使它看起来已正确安装，我也无法运行 pyinstaller。

1. 我通过“环境变量”将以下路径添加到系统路径:

C:\Users\awilliamson\AppData\Local\Programs\Python\Python37-32\Scripts

我确保编辑“路径”并在上一个路径后添加分号。这是我生成的系统路径:

C:\Program Files (x86)\Intel\iCLS Client\;C:\Program Files\Intel\iCLS Client\;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Intel\UCRT\;C:\Program Files\Intel\UCRT\;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files (x86)\Intel\Intel(R) Management Engie Components\IPT;C:\Program Files\Intel\Intel(R) Management Engine Components\IPT;C:\Users\awilliamson\AppData\Local\Programs\Python\Python37-32\Scripts

添加到“Path”后，我打开命令提示符并输入以下内容并运行:

pip安装pyinstaller

这是输出:

它似乎已经开始工作 - 所以我运行了:

看起来还是不错的。然后我通过运行以下命令来测试 pyinstaller:

pyinstaller

这是输出:

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

C:\Users\awilliamson>

这些都是我在“环境变量”中的路径

用户:

C:\Users\awilliamson\AppData\Local\Programs\Python\Python37-32\;C:\Users\awilliamson\AppData\Local\Programs\Python\Python37-32\Scripts;%PyCharm Community Edition%

系统:

C:\Program Files (x86)\Intel\iCLS Client\;C:\Program Files\Intel\iCLS Client\;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Intel\UCRT\;C:\Program Files\Intel\UCRT\;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files (x86)\Intel\Intel(R) Management Engie Components\IPT;C:\Program Files\Intel\Intel(R) Management Engine Components\IPT;C:\Users\awilliamson\AppData\Local\Programs\Python\Python37-32\Scripts

我尝试解决该问题的方法:

1. 卸载/重新安装 Python 和 pyCharm
2. 重新启动计算机
3. 更新计算机
4. 研究了系统恢复，但我认为恢复点太新了
5. 使用 Regedit 恢复旧的路径扩展。

Answer 1

感谢 M. R.，我终于弄清楚了

我确实安装了 pyinstaller；但是，它没有出现在脚本中。因此，如果您运行的是 Python 2，请使用:

pip install https://github.com/pyinstaller/pyinstaller/archive/develop.tar.gz

对于 Python 3:

pip3 install https://github.com/pyinstaller/pyinstaller/archive/develop.tar.gz

有关这方面的信息可以在以下位置找到:

https://www.pyinstaller.org/downloads.html

运行上面的正确代码后，pyinstaller卸载了旧版本并安装了新版本，然后出现在脚本中并再次工作。
