今天在查看python文檔中關(guān)于 calendar 模塊的內(nèi)容時(shí)，發(fā)現(xiàn) 3.7 版本增加了一些內(nèi)容，故想使用 pyenv 安裝。

環(huán)境：

• centos 7

# pyenv install --list
# pyenv install 3.7.3

出現(xiàn)以下錯(cuò)誤：

問過度娘，解決方案如下：

# yum install libffi-devel -y
.
.
.
Installed:
  libffi-devel.x86_64 0:3.0.13-18.el7                                                                                                                                 

Complete!

完成 libffi-devel的安裝后，重新運(yùn)行上面的命令即可。
