问题 I am following a tutorial on virtual environments (for Python) from the Coding Train (Here: https://www.youtube.com/watch?v=nnhjvHYRsmM). As I follow the tutorial, I see that, when which python is typed (in Terminal), the output should be the venv's Python in which it had installed. However, my system, for whatever reason this may be, decided to use it's own installed version of Python, instead. This means that all the dependencies (/modules) are screwed up and that I can't simply type out

在virtualenv中使用Python 3

由 蓝咒 提交于 2021-02-11 02:27:53
问题： Using virtualenv , I run my projects with the default version of Python (2.7). 使用 virtualenv ，我使用默认版本的Python（2.7）运行项目。 On one project, I need to use Python 3.4. 在一个项目中，我需要使用Python 3.4。 I used brew install python3 to install it on my Mac. 我使用 brew install python3 将其安装在Mac上。 Now, how do I create a virtualenv that uses the new version? 现在，如何创建使用新版本的virtualenv？ eg sudo virtualenv envPython3 例如sudo virtualenv envPython3 If I try: 如果我尝试： virtualenv -p python3 test I get: 我得到： Running virtualenv with interpreter /usr/local/bin/python3 Using base prefix '/usr/local/Cellar/python3/3.4.0_1

Pyenv: How to 'rebuild' virtualenvs after rebuilding python

由 孤人 提交于 2021-02-10 13:29:10
问题 I rebuilt python 3.7 to get pyinstaller to work on Mac, and it seems to have deleted all my virtualenvs using 3.7.0. The .python-version files still exist, and they point at the location I would expect. But when I run 'pyenv virtualenvs' there's no python3 environments at all, and in the project directory, the python command doesn't work at all. 3.7.0/envs/some-scripts``` ```$ ls ~/.pyenv/versions/3.7.0/envs/some-scripts/bin/ activate chardetect macho_find netaddr pydoc pyi-makespec python3

问题 I was trying to install the bokeh Python package via pip but I was thrown this error: error: Microsoft Visual C++ 10.0 is required (Unable to find vcvarsall.bat). I fixed that error by installing Microsoft Visual C+ and installed successfully after that. However, now I want to install bokeh inside my virtual environment which I created with virtualenv. My intent is to build a Flask app. I got the same error again, but this time I have no idea what to do. Any help would be greatly appreciated.

How to customize virtualenv shell prompt

由 一曲冷凌霜 提交于 2021-02-07 14:33:21
问题 How do you define a custom prompt to use when activating a Python virtual environment? I have a bash script for activating a virtualenv I use when calling specific Fabric commands. I want the shell prompt to say something like "(fab)" so I can easily distinguish it from other shells I have open.
