# pip3安装问题

## 1、直接在命令终端输入：pip3

```shell
raise DistributionNotFound(req, requirers)

pkg_resources.DistributionNotFound: The 'pip==20.0.2' distribution was not found and is required by the application
```

## 2、更新pip：

```shell
% sudo python -m pip install -U pip
```
### 结果提示如下：

```shell
subprocess.CalledProcessError: Command '('lsb_release', '-a')' returned non-zero exit status 1.
```

## 3、查找lsb_release的位置：

```shell
 % find / -name lsb_release
```
### 结果提示如下：

```shell
/usr/bin/lsb_release
```

## 4、删除lsb_release：

```shell
% sudo rm -rf /usr/bin/lsb_release
```

## 5、再次更新pip：

```shell
% sudo python -m pip install -U pip
```
### 结果提示如下：

```shell
Successfully uninstalled pip-19.0.3
Successfully installed pip-20.2.4
```
#### 20.2.4就是新的pip版本号

## 6、修改默认的版本号：

```shell
% sudo vim /usr/bin/pip3
```
### 把里面的pip==修改如下：
```shell
#!/usr/bin/python3
# EASY-INSTALL-ENTRY-SCRIPT: 'pip==20.2.4','console_scripts','pip3'
__requires__ = 'pip==20.2.4'
import re
import sys
from pkg_resources import load_entry_point

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(
        load_entry_point('pip==20.2.4', 'console_scripts', 'pip3')()
    )
```

### 修改完保存退出，然后就可以用pip3安装python需要的模块了
### 如安装pygame:
```shell
% pip3 install pygame
```

### 注意：python3.8以上不支持pygame，所以本处默认用python3.7
