# 安装环境

## 安装xwPython

### 问题

当前使用的python环境为python 3.10.2[wxPython 4.1.1目前最高版本支持仅到Python 3.9](https://discuss.wxpython.org/t/wxpython-for-python-3-10-1-windows-64bit/35745)，因此在安装时会出现如下问题, 主要是：

note: This error originates from a subprocess, and is likely not a problem with pip.

error: legacy-install-failure

╰─> wxPython

note: This is an issue with the package mentioned above, not pip.

hint: See above for output from the failure.

```

### 解决办法：

1. 降级Python 3到python 3.9或更低

2. 安装wxPython310

```

pip3 install wxpython310

```
