Question

我已经运行pip install pandas并且似乎收到了大量的警告，但最终似乎已经成功安装了所有内容。我也跑pip install requests。

当我用这一行调用函数时：

getTeamRoster("http://modules.ussquash.com/ssm/pages/leagues/Team_Information.asp?id=11325")

我收到此错误（似乎不喜欢read_html调用并要我安装lxml？）：

Traceback (most recent call last):
  File "SquashScraper.py", line 51, in <module>
    main()
  File "SquashScraper.py", line 48, in main
    getTeamRoster("http://modules.ussquash.com/ssm/pages/leagues/Team_Information.asp?id=11325")
  File "SquashScraper.py", line 39, in getTeamRoster
    tables = pd.read_html(requests.get(teamURL).content)
  File "/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages/pandas/io/html.py", line 865, in read_html
    parse_dates, tupleize_cols, thousands, attrs, encoding)
  File "/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages/pandas/io/html.py", line 718, in _parse
    parser = _parser_dispatch(flav)
  File "/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages/pandas/io/html.py", line 677, in _parser_dispatch
    raise ImportError("lxml not found, please install it")
ImportError: lxml not found, please install it

有什么想法在这里发生了什么？

如果需要，很高兴提供更多信息。

谢谢， bclayman

Answer 1

请注意，您收到以下错误消息：

ImportError: lxml not found, please install it

这意味着您需要在Linux上安装python-lxml软件包。

在Ubuntu上

sudo apt-get -y install python-lxml

在Fedora上

sudo yum -y install python-lxml

在Mac上

brew install libxml2
brew install libxslt
STATIC_DEPS=true sudo pip install lxml

Answer 2

如果您使用的是Mac，则必须下载并安装开发人员工具，这可以通过以下命令实现：

xcode-select --install

在我执行pip install lxml
