I have encountered a question about Jinja2 package now. I hope you can take the time to help me answer it. Thank you!

• Firstly, I have successfully built the virtual machine image of ubuntu now：

make: 离开目录“/home/iie-iisd/s2e/images”
SUCCESS: [image_build] Built image(s) 'ubuntu-22.04-x86_64'

• Then I execute the following command to test (the ubuntu virtual machine image in the test is a directory)
  

$ s2e new_project -i /home/iie-iisd/s2e/images/ubuntu-22.04-x86_64 /home/iie-iisd/project/test-01/test-01

• At present, there seems to be no problem, but after a while, an error was reported as follows:

ModuleNotFoundError: No module named 'jinja2'

• It reminds me that I am missing the package for Jinja2, but I checked and found out that I have this package. Why is this problem still present?

[S2E:s2e] (venv) iie-iisd@vm:~/桌面/s2e-env$ pip list
Package    Version
---------- -------
Jinja2     3.1.2
MarkupSafe 2.1.3
pip        23.2.1
setuptools 59.6.0

• I would greatly appreciate it if you could help me solve this problem!

Hi,

Make sure you run all the s2e commands inside an active venv.

Do you mean I need to start over from scratch?
