ubuntu16.04安装python3.7+pipenv
1. 安装python3.7
ubuntu默认是python3.5
1. 下载、解压、编译，安装
# 下载python3的安装包
wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz
# 解压源码：
tar -zxvf Python-3.7.0.tgz -C ~
cd Python-3.7.0
# 安装源码编译所需的各种依赖库：（Ubuntu16.04环境下）
sudo apt-get install zlib1g-dev libbz2-dev libssl-dev libncurses5-dev libsqlite3-dev libreadline-dev tk-dev libgdbm-dev libdb-dev libpcap-dev xz-utils libexpat1-dev liblzma-dev libffi-dev libc6-dev
# 配置安装位置 配置优化：
./configure --prefix=/usr/local --enable-optimizations
# 编译：
make -j 4
# 安装：
sudo make install
sudo make altinstall
2. 创建python3.7的软连接
cd /usr/bin/
mv python python.backup # 备份python
ln -s /usr/local/bin/python3.7 /usr/bin/python # 为p3.7创建软连接名为python
ln -s /usr/local/bin/pip3.7 /usr/bin/pip3.7 # 为pip3.7创建软连接为pip3.7
python -V # 查看python版本
pip3.7 -V # 查看pip版本
2.安装pipenv
1.安装
pip3.7 install --user pipenv
2. 修改配置项
使用命令：python -m site --user-base和python3 -m site --user-base,查看电脑用户的基础目录路径，会得到：
类似与 /home/python/.local 或 /home/python/./local/lib/python3.6/site-packages
使用命令：vi ~/.profile,在最后添加：
export PATH=$PATH:/home/python/.local/bin # 注意：末尾添加/bin
执行：source ~/.profile
若报错:
/usr/bin/python: Error while finding module specification for 'virtualenvwrapper.hook_loader' (ModuleNotFoundError: No module named 'virtualenvwrapper')
virtualenvwrapper.sh: There was a problem running the initialization hooks.
If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/bin/python and that PATH is
解决：
sudo pip3 install virtualenv virtualenvwrapper
source .bashrc
再次：
source ~/.profile
执行pipenv查看是否成功。
