pyinstaller第三方库打包文件“ValueError”：找不到文件_python找不到pyinstaller文件

安装pyinstaller，按照命令提示安装成功，但打包文件的时候总是失败，如下：

错误提示：ValueError: script’C:\Users\Administrator\SevenDigitsDraw.py’ not found
刚开始我一直不理解，因为我明明安装pyinstaller成功了，但是打包文件一直这样。后来我又细看了上边的提示，以为是python版本与所安装的pyinstaller版本不一致造成的，但后来证明我是多想了…

话不多说，错误原因及解决方案：
（1）错误原因
我想打包的文件在E盘中，但我直接在C盘的情况下输入了“pyinstaller - F SevenDigitsDraw.py”，所以才导致文件找不到。
（2）解决办法
涉及到在windows命令行中换盘的问题，以我的E盘为例：
1、先将C盘换为E盘：直接输入“ e: ” ——>即转为E盘

C:\Users\Administrator>e:
1

2、接着输入自己所要打包文件所要的目录，一定要在前边加上cd！即**“ cd <文件夹名称>”**

E:\>cd python编程
1

3、开始打包——pyinstaller -F <文件名.py>，等待运行即可
4、恭喜你，打包成功！
