Python 安装pycurl 7.19.0时出错

我需要安装这个特定版本（7.19.0）的pycurl

当我尝试使用此命令安装时：

pip安装pycurl==7.19.0

我收到这个错误

Failed building wheel for pycurl   Running setup.py clean for pycurl Failed to build pycurl Installing collected packages: pycurl

..... // MULTIPLE LINES

如何安装此特定版本

我正在使用Ubuntu 16

谢谢

我遇到了同样的错误，无法找到在Ubuntu 16.04上安装

pycurl==7.19.0

。相反，我切换到了

pycurl==7.43.0

，pip安装得很好。

在环境中运行：

apt-cache depends python-pycurl

它将输出类似于：

  Depends: python
  Depends: python
  Depends: <python:any>
    python
  Depends: libc6
  Depends: libcurl3-gnutls
  Suggests: libcurl4-gnutls-dev
  Suggests: python-pycurl-dbg
  Suggests: python-pycurl-doc

现在检查是否可以在env中安装pycurl：

pip install pycurl

如果它不工作并抛出错误“无法创建轮子”或类似错误，请进一步执行以下操作：

apt-cache search gnutl | grep dev

输出为：

libcurl4-gnutls-dev - development files and documentation for libcurl (GnuTLS flavour)
libgnutls-dev - GNU TLS library - development files
libgnutls28-dev - dummy transitional package for GNU TLS library - development files
libneon27-gnutls-dev - Header and static library files for libneon27 (GnuTLS enabled)
libsoup-gnome2.4-dev - HTTP library implementation in C -- GNOME support development files

在我的情况下，安装后：

sudo apt-get install libgnutls-dev

我能够在virtualenv中安装PyCurl

你能试试

sudo-apt-get-install-python-dev

并重试

pip-install

？sudo-apt-get-install-libgnutls-dev帮我完成了这个技巧（Ubuntu 16.04），如果你得到错误包libgnutls-dev不能用于最后一个命令，然后，使用

sudo-apt-get-install-libgnutls-dev

代替

sudo-apt-get-install-libgnutls28-dev

THx@Sherlock。我使用的是Ubuntu18.04，你的建议有效（与答案中最初的建议相反）。

sudo apt-get install libgnutls-dev
