python - 用 pip 安装 plyvel

Question

我在尝试安装 plyvel 时遇到此错误:

  Running setup.py install for plyvel

谁能解释一下这是怎么回事，我该如何解决？

需要安装leveldb开发包。

基于 deb 的发行版:

sudo apt-get install libleveldb-dev

基于 RPM 的发行版:

sudo yum install leveldb-devel

请注意 dnf 正在缓慢但肯定会取代 yum。如果您的发行版使用 dnf(例如，Fedora 23 和更新版本)，您可以将它放在那里而不是 yum:

sudo dnf install leveldb-devel
