SECRET_KEY errors with environment variables

问题 I am working through the TaskBuster Django tutorial whose goal is to help in the process of setting up a good development setup for a project. When I run the command echo $SECRET_KEY In either my "Dev" environment or my "Test" environment I get the same output so I believe that my $ENVIROMENTS/bin/postactivate and predeativate variables are set up correctly. my base.py folder contains # Build paths inside the project like this: os.path.join(BASE_DIR, ...) import os BASE_DIR = os.path.dirname

virtualenv 可以用来建立一个专属于项目的python环境,保持一个干净的环境。只需要通过命令创建一个虚拟环境,不用的时候通过命令退出,删除。实践证明用虚拟环境能避免很多糟心的事。 下面介绍一下安装方法: 安装 virtualenv; 安装 virtualenvwrapper; 安装 Numpy,Scipy,Matplotlib 等Python科学计算的库; 1.安装 virtualenv $ sudo pip install virtualenv 然后建立一个测试目录: $ mkdir testvirtual $ cd testvirtual 就可以成功创建一个虚拟环境 env1: $ virtualenv env1 进入env1: source env1/bin/activate 退出: deactivate 2.安装 virtualenvwrapper Virtaulenvwrapper是virtualenv的扩展包,可以更方便地新增,删除,复制,切换虚拟环境。 运行下面命令就安装成功了,默认安装在 /usr/local/bin下面: $ sudo easy_install virtualenvwrapper 接下来创建一个文件夹,用来存放所有的虚拟环境: $ mkdir ~/workspaces $ cd ~/workspaces

Module installed with PIP in virtualenv not found

问题 Getting a very strange error. I am making a virtual environment and initializing it with a pip requirements.txt file, but when I go to run code in the activated environment, the virtual environment interpreter claims to be missing some (and only some) of the modules: (venv) $ pip list certifi (2017.7.27.1) chardet (3.0.4) decorator (4.1.2) idna (2.5) ipython (6.1.0) ipython-genutils (0.2.0) jedi (0.10.2) numpy (1.13.1) olefile (0.44) pexpect (4.2.1) pickleshare (0.7.4) Pillow (4.2.1) pip (9.0

大咖揭秘Java人都栽在了哪?点击免费领取《大厂面试清单》,攻克面试难关~>>> 本文介绍了如何下载鸿蒙系统源码,如何一次性配置可以编译三个目标平台(Hi3516,Hi3518和Hi3861)的编译环境,以及如何将源码编译为三个目标平台的二进制文件。 坑点总结: 下载源码基本上没有太多坑,可以很顺利的进行 编译源码主要的一个大坑是,默认版本的scons依赖python 3.7+,鸿蒙基础编译代码依赖python3,需要安装python 3.7+,并和当前系统上的python2.7/python3.6和谐共处!解决方法一般有两种: 使用virtualenv管理多个版本的python环境,这种方式好处是只在当前shell会话生效不影响系统环境、其他用户和其他shell会话,缺点是使用前需要source active脚本稍微有点麻烦; 使用update-alternatives管理系统的多个版本python命令,这种方式需要切换系统的链接/usr/bin/python和/usr/bin/python3,可能会影响依赖python的应用程序(例如apt)的正常使用、其他用户和其他shell会话; 准备环境 本节介绍下载、编译和烧写鸿蒙系统所需的软硬件环境。 硬件环境 其中,Linux主机用于源码下载和编译,Windows主机用于烧写程序到单板以及源码编辑。 软件环境 硬件 说明

virtualenv “workon” doesn't work

孤人 提交于 2020-11-27 02:00:59
问题 I made a virtualenv environment for a project. "workon projectname" worked and activated the environment but after I shut down my laptop it starts not working. Could someone tell me how to fix this? 回答1: Since I don't have enough reputation to comment I'll simply attempt an answer as I think I know what the issue is. Firstly, if you could provide more details as to what you mean by "not working" I will edit my answer if need be and attempt to help more. Typically this happens because
