我需要安装这个特定版本（7.19.0）pycurl。
当我尝试使用此命令安装时：
点安装pycurl==7.19.0
我收到此错误。
Failed building wheel for pycurl Running setup.py clean for pycurl Failed to build pycurl Installing collected packages: pycurl

如何安装此特定版本？
我正在使用 Ubuntu 16。
谢谢！
在环境中运行：
apt-cache depends python-pycurl
它将输出类似于以下内容的内容：
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
安装 libcurl4-gnutls-dev：
sudo apt-get install libcurl4-gnutls-dev
现在检查是否可以在 env 中安装 pycurl：
pip install pycurl
如果它不起作用并抛出错误"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
就我而言，安装后：
sudo apt-get install libgnutls-dev
我能够在虚拟环境中安装 PyCurl。
我遇到了同样的错误，无法找到在 Ubuntu 16.04 上安装pycurl==7.19.0的方法。相反，我切换到pycurl==7.43.0，pip安装得很好。
apt-get install libpython3.x-dev libnss3 libnss3-dev
修复了此问题。将 X 替换为您的 Python 版本
