python - IntelliJ conda 集成

Question

我在 myFile.py 中有:

import pkg_resources
installed_packages = pkg_resources.working_set
installed_packages_list = sorted(["%s==%s" % (i.key, i.version)
                                  for i in installed_packages])
print(installed_packages_list)
import rospy

我在 ros env 中有 ros 包

(ros) $ pip list | grep rospy
rospy                         1.11.21   
rospy-message-converter       0.4.0   

如果我在设置 ros conda env 后从 IDEA 运行此文件

/home/username/anaconda3/envs/ros/bin/python /home/username/Projects/Python/myProject/myFile.py
['argparse==1.4.0', 'catkin-pkg==0.4.9', 'certifi==2018.10.15', 'docutils==0.14', 'numpy==1.15.4', 'pip==18.1', 'pyparsing==2.3.0', 'python-dateutil==2.7.5', 'python==2.7.15', 'pyyaml==3.13', 'rospkg==1.1.7', 'setuptools==40.6.2', 'six==1.11.0', 'wheel==0.32.3', 'wsgiref==0.1.2']
Traceback (most recent call last):
  File "/home/username/Projects/Python/myProject/myFile.py", line 8, in <module>
    import rospy
ImportError: No module named rospy

Process finished with exit code 1

我使用了以下配置:

但是，如果我在终端上运行相同的命令，它就会起作用:

在终端上，即使没有 conda activate ros:

那么IDEA没有执行打印的命令？它正在运行其他东西吗？为什么我看到从 IDEA 内部运行的 conda env ros 安装的软件包少得多？如何解决此问题？

我在

• IDEA 2018.3
• Ubuntu 14.04

更新:

我已经配置了 conda env，并像这样验证了它:

在终端上:

$ conda activate ros
(ros) $ python

当您尝试在系统终端(IDEA 之外)中运行此脚本时，您是否使用相同的解释器？如果没有，请重试，但使用与 IDEA 中使用的相同的解释器。你有同样的错误吗？

如果没有，请尝试以下操作:

• 使用相同的解释器在系统终端中运行import os
• 运行print(os.environ['PATH'])
• 复制结果并将其作为 PATH 环境变量添加到您的运行/调试配置
