问题 I created a Windows (10) Python virtual environment (env3.7.3).

问题 I am fairly new to creating Python applications. I have fooling around with some small tutorials and applications using PyCharm and have always created a new project using the Virtualenv environment, ending up with a "venv" folder under my project folder. I have not had any problems with this, but then again I have not done any large projects. However, I have been wanting to learn Flask want to try to create a new Flask project the proper way. I see in many tutorials that people are creating

问题 I'm trying to create a virtual environment for my current Django project using python3 -m venv env however the command doesn't create any directory with bin/include/lib folders. What exactly am I missing here? 回答1: I was having this same problem. I was able to get venv working by uninstalling Python and reinstalling it (I'm using the Anaconda distribution). The py -m venv test command still doesn't have any output after running it, but now it creates a folder for me and I can activate the

问题 1) I installed virtualenv using pip. 2) I ran the command virtualenv venv 3) Then I ran source venv/bin/activate but it says that there is no such file or directory. When I cd into venv/bin I find 3 things - python, python 2.7, and python 3.5. Does anyone know the problem? 回答1: i have had the same problem. and what i did is just run the command virtualenv env again. And then more files were generated under directory env/bin, including the activate file. it's so weird. maybe you can have more

问题 I am learning Django. I installed two different versions of python on my laptop, 2 and 3. I configured my Laptop to use Python 3, so when I check version using the command line, I got this output. Then, I installed the Django and Python Virtual Environment following this link. I could install the Django and Virtual Environment successfully. But my virtual environment is using the python 2. When I check the version in the virtual environment, I got this output. So, how can I configure that

问题 I isolate my data science projects into virtual environments using pipenv . However, running a Jupyter notebok does not access the local environment and uses the default IPyKernel. I've seen that you can register virtual environments from within the environment, but this requires installing the ipykernel package which itself requires Jupyter! Is there anyway to avoid this and just use a single Jupyter install for all virtual environments? 回答1: Generally, you'd install jupyter once and do the

问题 I'm using Ubuntu system with python 3.5 installed by default. When I use the venv module to create virtual environment, I can't find the standard library in my virtual environment but only the binary file for python interpreter. However I can import standard library modules in my python script when I switch to use this virtual environment. So how does venv work? Does the newly created virtual environment just use the standard library of the system python? If so, what if I want to create a

问题 I am trying to install packages in a python 3.6.3 virtual environment. I keep getting errors. I have tried pip with --ignore-installed flag like: pip install -I -r package-list.txt .
