我想知道如何在 Heroku 服务器上使用 BeautifulSoup4。
在我的requirements.txt文件中我写了:“BeautifulSoup==4.9.1”,
但我收到错误:
ERROR: Could not find a version that satisfies the requirement BeautifulSoup==4 (from -r /tmp/build_d624b770_/requirements.txt (line 1)) (from versions: 3.2.0, 3.2.1, 3.2.2) ERROR: No matching distribution found for BeautifulSoup==4 (from -r /tmp/build_d624b770_/requirements.txt (line 1))
那么我该如何使用BeautifulSoup4呢?
