【已解决】Mac本地用pipenv搭建Flask开发环境

期间,为了在本地开发Flask,先去本地Mac中安装pipenv虚拟环境。

最开始不小心,好像是安装了python2的pipenv了:

<code>➜  robotDemo python --version

➜  robotDemo which python

➜  robotDemo  python -m site --user-base

结果报错:

但是发现好像应该安装Python3的pipenv:

https://segmentfault.com/a/1190000012837890

“作者推荐在python3下边安装,会提高与virtualenv的兼容性。”

但是此处默认好像是用python2安装的。

http://www.dongwm.com/archives/使用pipenv管理你的项目/

“brew install python3  # 如果已经安装了可以忽略”

去找找,此处的记得之前安装过Python3的,查查之前是否安装,已经安装的版本:

【已解决】Mac中用brew查看之前已安装过的Python3的信息

那就去用python3去安装试试:

先重新安装python3中的pip

<code>➜  robotDemo python3 -m pip install --upgrade --force-reinstall pip

</code>

然后顺带看看pip3:

<code>➜  robotDemo which pip3

然后再看看能否找到刚安装的程序了,分别看看版本:

可见,进入pipenv的shell后,就自动激活了虚拟环境了,python也是用的默认的Python3的版本了(应为是用python3的pip3安装的pipenv)

看看对应生成的文件:

看看此时的PATH:

</code>

添加了当前的虚拟环境的路径了。

-》所以前面找python时,找到的是虚拟环境中的python了。

【后记1】

还是为了避免之前安装的python2的pipenv和python3的pipenv互相影响,去删除掉python2的pipenv吧:

<code>➜  robotDemo pip --version
whpip 10.0.0 from /usr/local/lib/python3.6/site-packages/pip (python 3.6)
➜  robotDemo which pip
pip: aliased to noglob pip
➜  robotDemo pip uninstall pipenv
Uninstalling pipenv-11.10.0:
  Would remove:
    /Users/crifan/Library/Python/3.6/bin/pewtwo
    /Users/crifan/Library/Python/3.6/bin/pipenv
    /Users/crifan/Library/Python/3.6/bin/pipenv-resolver
    /Users/crifan/Library/Python/3.6/lib/python/site-packages/pipenv-11.10.0.dist-info/*
    /Users/crifan/Library/Python/3.6/lib/python/site-packages/pipenv/*
Proceed (y/n)? y
  Successfully uninstalled pipenv-11.10.0
➜  robotDemo where pipenv
pipenv not found
</code>

好像是把之前的python3的pipenv删除掉了。

所以先去恢复.bashrc的PATH,确认pip和pip3以及python 和python3是没问题的 :

<code>➜  robotDemo source ~/.bashrc
➜  robotDemo echo $PATH
/Users/crifan/.nvm/versions/node/v5.4.1/bin:/Users/crifan/Library/Python/3.6/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
➜  robotDemo vi ~/.bashrc
➜  robotDemo cat ~/.bashrc

export NVM_DIR="/Users/crifan/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] &amp;&amp; . "$NVM_DIR/nvm.sh"  # This loads nvm


➜  robotDemo source ~/.bashrc
➜  robotDemo echo $PATH

【总结】

所以此处Mac中本地安装Python3的pipenv的过程就是:

背景是此处之前已经用brew安装过了python3,如果没有,则先去安装:

<code>brew install python3
</code>

然后再去更新python3中的pip:

<code>python3 -m pip install --upgrade --force-reinstall pip
</code>

然后再去,以用户模式安装pipenv:

<code>pip3 install pipenv --user
</code>

注:用户模式的话,不会对全局的python有影响。

然后再去把此处提示的,PATH中缺少的路径:

<code>/Users/crifan/Library/Python/3.6/bin
</code>

加到PATH中去:

先把:

<code>export PATH="/Users/crifan/Library/Python/3.6/bin:$PATH"
</code>

加到.bashrc中 -》为了以后每次启动电脑后,PATH中都包含该路径。

再去:

<code>source ~/.bashrc
</code>

是为了当前此刻,PATH中包含该路径。

这样命令行中就可以找到这些pipenv等工具了。

然后即可切换到你的项目所在的目录,再去:

<code>pipenv install
</code>

即可:

创建对应的虚拟环境所需内容,以及相关的Pipfile和Pipfile.lock

接着,进入对应的虚拟环境:

<code>pipenv shell
</code>

接着就可以做自己要做的事情了,比如安装某个库:

<code>pipenv install flask
</code>

使用完毕后,用:

<code>exit
</code>

或 快捷键:Control+D,即可退出虚拟环境。
