無法使用pip安裝lxml

Question

這是我用來安裝lxml的命令：

sudo pip install lxml

我在清理階段收到以下消息：

Cleaning up...
Command /usr/bin/python -c "import setuptools,     tokenize;__file__='/private/tmp/pip_build_root/lxml/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-rUFjFN-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /private/tmp/pip_build_root/lxml
Storing debug log for failure in /Users/georgejor/Library/Logs/pip.log

在那之后，我得到了：

ImportError: No module named lxml

請幫忙。 謝謝！

以下輸出來自pip.log：

Answer 1

只需安裝這些東西：

sudo apt-get install libxml2-dev libxslt-dev  python-dev  python-setuptools

然后再試一次：

pip install lxml

Answer 2

這是一個類似的問題。

安裝枕頭（和PIL）時出錯

你在使用MacOS嗎？ 也許您可以嘗試更新命令行工具並嘗試'brew'工具。 如果沒有，您可以嘗試再次安裝pip和easy_intall工具，並進行更新。

Answer 3

lxml有C依賴性，當我缺少libxslt或libxml2時，我經常遇到問題。 您確定所有非python依賴項都已安裝嗎？
