在CentOS 7中设置Python环境变量的步骤如下:
1. 打开命令终端,使用以下命令安装Python:
```bash
yum install python
```
2. 确认Python已正确安装,使用以下命令查看Python版本号:
```bash
python --version
```
3. 使用以下命令查找Python的安装路径:
```bash
which python
```
这将返回Python的安装路径,例如`/usr/bin/python`。
4. 打开`.bashrc`文件,使用以下命令:
```bash
vi ~/.bashrc
```
5. 在文件末尾添加以下内容:
```bash
export PATH=/usr/bin/python:$PATH
```
这将把Python的路径添加到系统的环境变量中。
6. 保存并退出`.bashrc`文件。
7. 重新加载`.bashrc`文件,使更改生效:
```bash
source ~/.bashrc
```
现在,您已经成功设置了Python环境变量。

centos 设置python环境变量
To set the Python environment variable on CentOS, you can follow these steps:
1. Determine the path to your Python installation by running the following command:
```
which python
```
This will give you the path to the Python executable, which is usually `/usr/bin/python` for the system Python installation.
2. Set the `PATH` environment variable to include the path to your Python installation. You can do this by running the following command:
```
export PATH=/path/to/python/bin:$PATH
```
Replace `/path/to/python/bin` with the path to your Python installation. For example, if your Python executable is located at `/usr/bin/python3.6`, the command would be:
```
export PATH=/usr/bin/python3.6:$PATH
```
3. To make this change permanent, add the `export` command to your shell's configuration file (e.g. `~/.bashrc` for Bash). Open the file in a text editor and add the following line at the end:
```
export PATH=/path/to/python/bin:$PATH
```
Save the file and exit the editor.
4. Finally, reload your shell's configuration by running:
```
source ~/.bashrc
```
This will apply the changes to your current shell session. You can now verify that the Python environment variable is set correctly by running `python` or `python3` in the terminal.

2. 然后确认 Python 安装成功,可以使用以下命令:
```
python --version
```
3. 打开 /etc/profile 文件,可以使用以下命令:
```
sudo vi /etc/profile
```
4. 在文件末尾添加以下内容:
```
# Python Environment Variables
export PYTHON_HOME=/usr/bin/python
export PATH=$PYTHON_HOME:$PATH
```
其中,PYTHON_HOME 的路径要根据实际安装路径进行修改。
5. 保存并退出文件,然后使用以下命令使配置文件生效:
```
source /etc/profile
```
6. 最后,可以使用以下命令验证环境变量是否配置成功:
```
echo $PATH
```
如果输出结果中包含 Python 的安装路径,则说明配置成功。
