我正在尝试在虚拟环境中使用 pip 安装一个包：
pip install fuse-python
但输出是
Downloading/unpacking fuse-python

Cleaning up...
Command python setup.py egg_info failed with error code 1 in /home/nicu/dev/bacula/ve/build/fuse-python
Storing debug log for failure in /home/nicu/.pip/pip.log
据我所知，pkg-config 和 PKG_CONFIG_PATH 有问题
我正在运行 ubuntu 14.04，并且输出dpkg -l | grep is（所以我的 fuse 安装不是‘太旧’）：
ii fuse 2.9.2-4ubuntu4 amd64 Filesystem in Userspace
ii gvfs-fuse 1.20.1-1ubuntu1 amd64 userspace virtual filesystem - fuse server
ii ifuse 1.1.2-0.1 amd64 FUSE module for iPhone and iPod Touch devices
ii libfuse2:amd64 2.9.2-4ubuntu4 amd64 Filesystem in Userspace (library)
更新：我使用 sudo apt-get install python-fuse 安装了它，但它是全局安装的：
ii python-fuse 2:0.2.1-9 amd64 Python bindings for FUSE (Filesystems in USErland)
答案1
安装sudo apt-get install libfuse-dev并重试。成功了。
