linux 下 pip3 报错“ File “/usr/bin/pip3”, line 9, in from pip import mainImportError: canno”处理

这个错误提示是你调用了 `find_intersections` 函数,但是传递给函数的参数中包含了单位,导致出现了参数数量不匹配的错误。
这个问题通常出现在使用了 Pint 库进行单位转换时。你可以尝试将参数中的单位去掉,或者使用 Pint 库提供的 `magnitude` 函数来获取参数的数值部分。例如,如果你的代码中有这样的语句:
```python
x = 10 * units.meters
a = 2 * units.seconds
b = 5 * units.seconds
find_intersections(x, a, b)
```
你可以改成这样:
```python
x = 10 * units.meters
a = 2 * units.seconds
b = 5 * units.seconds
find_intersections(x.magnitude, a.magnitude, b.magnitude)
```
或者这样:
```python
x = 10 * units.meters
a = 2 * units.seconds
b = 5 * units.seconds
find_intersections(x.to(units.dimensionless).magnitude, a.to(units.dimensionless).magnitude, b.to(units.dimensionless).magnitude)
```
这两种方法都可以将单位去掉,避免出现参数数量不匹配的错误。
