Moving node_modules location under a Python venv

由 余生颓废 提交于 2019-12-11 14:47:42
问题 I have a Python venv to develop a Django application and I use babel to transpile my javascript. Currently, I install node.js with nodeenv -p whilst working under my Python venv. Everything works fine if I have the node_modules and package.json folder at the root of my project, but it is messing up the project folder structure. I would rather have node_modules under venv : project_folder | |- venv |- node_modules package.json or even: project_folder | |- venv |- node |- node_modules package

Why conda cannot create environment with python=3.4 installed in it

问题 I have miniconda 3 installation and want to create conda environment with Python 3.4. I used the command: conda create -n myenv python=3.4 and get the error: PackagesNotFoundError: The following packages are not available from current channels: - python=3.4 I tried to change the version to 3.7, typing conda create -n myenv python=3.7 There was no error with version 3.7.

There is no activate when I am trying to run my virtual env

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? 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 try. I solved a similar problem by naming it venv2 when I ran virtualenv. I already had a virtual

When I checked, the virtualenv got installed in "/usr/local/lib/python3.5/dist-packages" location, so when I'm trying to create virtualenv using python3 -m venv ./venv1 it's throwing me errors: Error Command: ['/home/wgetdj/WorkPlace/Programming/Python
