在运行程序之前,我必须在终端中运行以下代码:

(venv) C:\Users\user pc\PycharmProjects\testProj>pip install -U pip --user
Requirement already up-to-date: pip in c:\users\user pc\pycharmprojects\testproj\venv\lib\site-packages (19.0.3)

(venv) C:\Users\user pc\PycharmProjects\testProj>pip install psycopg2 --user
Requirement already satisfied: psycopg2 in c:\users\user pc\pycharmprojects\testproj\venv\lib\site-packages (2.7.7)

所以,pip被安装了。
只有在运行此程序之后,我才必须运行我的程序,其中正在发生以下错误:
"C:\Users\user pc\PycharmProjects\testProj\venv\Scripts\python.exe" "C:/Users/user pc/PycharmProjects/testProj/auto.py"
The unique id is 1
Traceback (most recent call last):

    startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

Process finished with exit code 1

请您更清楚和具体的过程,以调试这个错误,因为我是非常新的编程领域。

最佳答案

此错误消息表示在“PATH”环境变量中找不到programdscsm047.exe。请在终端/cmd中键入echo %PATH%以查看路径变量。
您可能可以在C:\DSSAT47\DSCSM047.EXE下找到可执行文件
如果没有,请阅读here文档。
如果你真的在dscsm047.exe下找到C:\DSSAT47。然后你可以在终端运行这个

set PATH="C:\DSSAT47;%PATH%"
python  "C:/Users/user pc/PycharmProjects/testProj/auto.py"
