安装 pip 包时“正则表达式的构建轮失败”

Question

我在运行 Debian Stretch 的 Windows 10 WSL 上安装 pip 包时遇到问题。

在运行时sudo pip install invoice2data，python3-pip安装后我遇到了以下错误。

error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

Answer 1

WSL 与该问题无关，这是一个相当标准的错误。确保安装了以下软件包。使用apt-get install packagename. 此特定时间的问题已通过安装python-dev.python3python3-pipipython3build-essentialpython-devpython3-dev作为单个命令：sudo apt-get install python3 python3-pip ipython3 build-essential python-dev python3-dev

Answer 2

我在 Ubuntu 上运行 Python 3.5。我是如何安装regexPython 包的：$ sudo apt-get install libpython3.5-dev$ pip3 install regex --no-use-wheel背景研究详情：我Python.h通过使用apt-file来定位它来确定提供丢失文件的包名称。# install the apt-file package in case you don't have it$ sudo apt-get install apt-file# populate/refresh the local apt-file package data$ sudo apt-file update# search for /Python.h.  Since it's a C header file,# I also grep for /include to limit the results.$ sudo apt-file search /Python.h | grep /includelibpython2.7-dbg: /usr/include/python2.7_d/Python.hlibpython2.7-dev: /usr/include/python2.7/Python.hlibpython3.5-dbg: /usr/include/python3.5dm/Python.hlibpython3.5-dev: /usr/include/python3.5m/Python.hpypy-dev: /usr/lib/pypy/include/Python.h然后对我需要哪个包进行了有根据的猜测。忽略Python2，忽略调试（dbg），忽略pypy，从而留下libpython3.5-dev。
