【问题描述】:
当我使用 Jenkins 在 python 脚本下运行时,它会抛出错误。
Jenkins Cannot run program "python" CreateProcess error=2, The system cannot find the file specified
以下是我的代码,当我直接执行时它可以工作。
import _mssql,os,datetime
if (os.getenv('ColumnName').isspace() or not os.getenv('ColumnName')):
print("White space Entered")
else:
print(var)
我正在运行 Python 3.5。
谢谢。
尝试了 python -v 并得到同样的错误
The system cannot find the file specified

【问题讨论】:
-
在您的 jenkins 作业中,不要执行上述脚本,而是执行此命令 - “python -V”。如果成功执行,则执行此脚本为 - python "
-
您的代码无关紧要。找不到 python 可执行文件,因为它不在 PATH 中。尝试从詹金斯呼应路径。
-
遇到同样的错误。
-
jenkin 作业在哪台机器上执行? Windows 还是 Linux?
-
我在 windows 机器上运行并确认路径已添加到环境变量中。
