我无法安装pyPDF包根本找不到适用于pyPdf的发行版

Question

我试着安装这个包...

$ pip search pyPdf     
PyPDFLite                 - Simple PDF Writer.
pypdfocr                  - Converts a scanned PDF into an OCR'ed pdf using Tesseract-OCR and Ghostscript
pyPdf                     - PDF toolkit
PyPDF2                    - PDF toolkit
pyjon.reports             - Pyjon.Reports is a module bridging z3c.rml, genshi and pypdf together to provide a simple mean of creating templated pdf documents in python.
pypdf2xml                 - A reimplementation of pdftoxml in Python, using pdfMiner. Handles unicode characters better.
pypdflib                  - Pango Cairo based Python PDF Library
pypdf2table               - PDF table extraction tool

然后我运行install the package

$ pip install pyPdf                 
Downloading/unpacking pyPdf
  Could not find any downloads that satisfy the requirement pyPdf
  Some externally hosted files were ignored (use --allow-external pyPdf to allow).
Cleaning up...
No distributions at all found for pyPdf
Storing debug log for failure in /tmp/tmpgEc3B

有什么问题吗？

Answer 1

指定--allow-external，--allow-unverified选项：

pip install --allow-external pyPdf --allow-unverified pyPdf pyPdf

指定--allow-unverified隐含--allow-external；，但省略。

pip install --allow-unverified pyPdf pyPdf

Answer 2

pyPdf不再更新，您可以在其网站here上查看

所以你最好使用其他的包，比如pyPdf2。如果您坚持使用pyPdf，您可以尝试falsetru posted方法

Answer 3

如果您使用的是Debian/Ubuntu，可以使用标准仓库安装相应的包：

$sudo apt-get update
$sudo apt-get install python-pypdf
