我尝试在PyCharm中运行一个google ortools示例,得到了以下错误:
/Users/edamame/project/ortools/simple_program.py
Traceback (most recent call last):
File "/Users/edamame/project/ortools/simple_program.py", line 3, in <module>
from ortools.linear_solver import pywraplp
ModuleNotFoundError: No module named 'ortools.linear_solver'
Process finished with exit code 1
字符串
然而,如果我在PyCharm之外运行相同的代码(在相应的项目venv下),它工作得很好:
(venv) edamame$ pwd
/Users/edamame/project/ortools/
(venv) edamame$ python simple_program.py
Solution:
Objective value = 4.0
x = 1.0
y = 1.0
型
然后我试着在下面两种情况下打印:
import sys
print('\n'.join(sys.path))
型
输出:
在PyCharm中:
/Users/edamame/project/venv/bin/python
/Users/edamame/project/ortools/so_example.py

PyCharm外部:
(venv) edamame$ python so_example.py
/Users/edamame/project/ortools
/Library/Frameworks/Python.framework/Versions/3.6/lib/python36.zip
/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6

他们似乎是一样的,虽然.
如何让同样的代码在PyCharm中工作?

您在自定义
ortools
包和安装的包之间存在命名空间冲突。PyCharm默认将项目根(/Users/edamame/project
)添加到PYTHONPATH
,这导致了问题。重命名您的自定义
ortools
软件包,或者在PYCharm的专用运行配置中禁用将内容根目录添加到PYTHONPATH选项。mpbci0fu2#
环境变量PYTHONPATH是相关的。在这两种情况下,打印
sys.path
的值:字符串
在bash中,你可能会发现输入venv然后输入
$ open /Applications/PyCharm.app
(或者你的Mac上的任何名称)会很有帮助。这里是另一种方法。在pycharm中输入CMD-,(命令逗号)作为首选项,搜索Project Structure,右键单击edamame/project文件夹,然后选择alt-S Sources。这将把文件夹添加到pycharm中的路径中。同样,使用
print()
来验证sys.path
包含的内容是否与您期望的相同。
