我正在运行Windows 7和Python 3.7（32位）。我正在尝试使用命令提示符安装pyinstaller，但遇到了我可以解决的问题。
在决定更新pyinstaller并失败之前，我做了短暂的工作。在那之后，所有的地狱都崩溃了。作为实习生，我花了将近一整天的时间，试图弄清楚出了什么问题，并觉得自己处于机智。我知道这是我在寻求解决方案的过程中经常问到的问题，但我确实很挣扎。最令人沮丧的部分是我可以运行pip，但是即使看起来安装正确，我也无法运行pyinstaller。
我已通过“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”，并在上一个路径之后添加分号。这是我得到的系统路径：
C：\ Program Files（x86）\ Intel \ iCLS Client \; C：\ Program Files \ Intel \ iCLS
客户端\; C：\ Windows \ system32; C：\ Windows; C：\ Windows \ System32 \ Wbem; C：\ Windows \ System32 \ WindowsPowerShell \ v1.0 \; C：\ Program
文件（x86）\ Intel \ UCRT \; C：\ Program Files \ Intel \ UCRT \; C：\ Program Files

Files \ Intel \ Intel（R）管理引擎
组件\ IPT; C：\ Users \ awilliamson \ AppData \ Local \ Programs \ Python \ Python37-32 \ Scripts
添加到“路径”后，我打开命令提示符并键入以下内容并运行：
点安装pyinstaller
这是输出：

它似乎已经在工作-所以我跑了：

看起来还是不错的。因此，我通过运行以下命令测试pyinstaller：
pyinstaller这是输出：
C：\ Users \ awilliamson> pyinstaller'pyinstaller'无法识别为
内部或外部命令，可操作程序或批处理文件。

这些都是我在“环境变量”中拥有的路径

我尝试解决此问题的方法：
卸载/重新安装Python和pyCharm
重新启动电脑
更新电脑
研究了系统恢复，但是我认为恢复点太新了
使用Regedit恢复旧的路径扩展。
最佳答案
感谢M.R.
我确实安装了pyinstaller；但是，它没有出现在脚本中。因此，如果您正在运行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
有关此信息，请访问：
https://www.pyinstaller.org/downloads.html
在运行完上面正确的代码之后，pyinstaller卸载了旧版本并安装了新版本，然后出现在脚本中并且可以再次使用。
关于python - 有关pyinstaller的路径问题，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/56567522/
