要在Linux上安装virtualenvwrapper,您需要使用pip3安装virtualenvwrapper。您可以使用以下命令安装virtualenvwrapper:
```
pip3 install virtualenvwrapper
```
安装完成后,您需要配置virtualenvwrapper。您需要在.bashrc文件中添加以下行:
```
export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
source /usr/local/bin/virtualenvwrapper.sh
```
然后,您需要重新加载.bashrc文件:
```
source ~/.bashrc
```
现在,您可以使用virtualenvwrapper创建和管理虚拟环境了。例如,要创建一个名为myenv的虚拟环境,请使用以下命令:
```
mkvirtualenv myenv
```
要激活虚拟环境,请使用以下命令:
```
workon myenv
```
要退出虚拟环境,请使用以下命令:
```
deactivate
```

linux virtualenvwrapper
Virtualenvwrapper is a tool that simplifies the management of Python virtual environments in Linux. It provides a set of commands to create, activate, and delete virtual environments, making it easier to work with different Python projects with their own dependencies.
To use Virtualenvwrapper, you need to have Python and Virtualenv installed on your system. Here are the steps to set up Virtualenvwrapper on Linux:
1. Install Virtualenv:
```
$ pip install virtualenv
```
2. Install Virtualenvwrapper:
```
$ pip install virtualenvwrapper
```
3. Add the following lines to your shell startup file (e.g., `~/.bashrc` or `~/.bash_profile`):
```
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3 # Path to your Python interpreter
export WORKON_HOME=~/.virtualenvs # Directory to store virtual environments
source /usr/local/bin/virtualenvwrapper.sh # Path to virtualenvwrapper.sh
```
4. Reload the shell startup file:
```
$ source ~/.bashrc
```
5. Create a virtual environment:
```
$ mkvirtualenv myenv
```
6. Activate the virtual environment:
```
$ workon myenv
```
Now you can install Python packages within the virtual environment without affecting your system-wide Python installation. You can also switch between different virtual environments using the `workon` command.
Remember, Virtualenvwrapper is just a wrapper around Virtualenv, so it uses the same underlying mechanisms for creating and managing virtual environments. It provides additional convenience commands and organizes virtual environments in a more structured way.
如何在window下安装 virtualenvwrapper
在 Windows 上,安装 virtualenvwrapper 的步骤与在 Linux 或 macOS 上略有不同。您可以按照以下步骤进行操作:
1. 安装 virtualenv 和 virtualenvwrapper:
```
pip install virtualenv virtualenvwrapper-win
```
2. 创建一个目录用于存放 Python 虚拟环境。在 Windows 上,您可以将其创建在任何您喜欢的位置。
```
mkdir C:\path\to\envs
```
3. 打开您的 shell 配置文件,例如 PowerShell 或 Git Bash:
```
notepad $PROFILE
```
4. 在文件末尾添加以下内容:
```
$ENV:WORKON_HOME = 'C:\path\to\envs'
$ENV:VIRTUALENVWRAPPER_PYTHON = 'C:\Python\python.exe'
. 'C:\Python\Scripts\virtualenvwrapper.ps1'
```
注意,如果您的 Python 安装位置不同,则需要将 `VIRTUALENVWRAPPER_PYTHON` 的值更改为正确的路径。
5. 让配置文件生效:
```
. $PROFILE
```
6. 现在,您可以使用 `mkvirtualenv` 命令创建新的 Python 虚拟环境了,例如:
```
mkvirtualenv myenv
```
这将创建一个名为 `myenv` 的虚拟环境,并自动激活它。您可以使用 `workon` 命令列出所有虚拟环境,并使用 `deactivate` 命令退出当前的虚拟环境。
