Could not find a version that satisfies the requirement PyPDF2 (from versions: none)
To resolve the issue with the PyPDF2 library, you can try the following steps:
1. Make sure you have the latest version of pip installed:
```
pip install --upgrade pip
```
2. Check if PyPDF2 is available in the Python Package Index (PyPI) by running:
```
pip search PyPDF2
```
If it's available, you should see a list of versions that are compatible with your Python version.
3. If PyPDF2 is listed, you can install a specific version by running:
```
pip install PyPDF2==<version>
```
Replace `<version>` with the specific version you want to install.
4. If PyPDF2 is not available in PyPI or you encounter any other issues, you can try an alternative library called `PyPDF4`. Install it using the following command:
```
pip install PyPDF4
```
Remember to update your code to use `PyPDF4` instead of `PyPDF2` if you decide to go with this alternative.
I hope this helps! Let me know if you have any further questions.
error: expected an expression
This error typically occurs when the compiler or interpreter is expecting to see a valid expression in a specific context, but instead encounters something that does not evaluate to a value.
For example, consider the following code snippet:
```
if (x == 5) {
printf("x is equal to 5");
} else
```
Here, the `else` statement is incomplete and does not provide an expression that the compiler can use to decide what to do next. This will result in the "expected an expression" error.
To fix this error, you need to provide a valid expression that the compiler can evaluate. In the above example, you could complete the `else` statement like this:
```
if (x == 5) {
printf("x is equal to 5");
} else {
printf("x is not equal to 5");
}
```
Now, the compiler has a valid expression to evaluate and the error should be resolved.
