PyPDF2在终端已经安装过了，在pycharm新建项目后又说没有，究竟怎么回事

明明安装了PyPDF2， 怎么还出现这个问题？

img

import os
import PyPDF2

from PyPDF2 import PdfFileMerger

target_folder = '/Users/ericlam3288/Desktop/test'

pdfs = []

#Find all pdf files in a folder
for file in os.listdir(target_folder):
    if file.lower().endswith('.pdf'):
        pdfs.append(file)

#PDFs are merged
merger = PdfFileMerger()
for pdf in pdfs:
    merger.append(pdf)

#Output a merged pdf file
merger.write('Merged_2.pdf')
merger.close()

确定终端环境和pycharm使用环境, 不是同一环境, 需要单独在使用环境中安装

路径写得有问题吧:
target_folder = '/Users/ericlam3288/Desktop/test'
改成:
target_folder = r'\Users\ericlam3288\Desktop\test'
