折腾：
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：

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 Collecting pip Downloading https://files.pythonhosted.org/packages/62/a1/0d452b6901b0157a0134fd27ba89bf95a857fbda64ba52e1ca2cf61d8412/pip-10.0.0-py2.py3-none-any.whl (1.3MB) 100% |████████████████████████████████| 1.3MB 746kB/s Installing collected packages: pip Found existing installation: pip 9.0.3 Uninstalling pip-9.0.3: Successfully uninstalled pip-9.0.3 Successfully installed pip-10.0.0 </code>
然后顺带看看pip3：
<code>➜ robotDemo which pip3 /usr/local/bin/pip3 ➜ robotDemo ll /usr/local/bin/pip* -rwxr-xr-x 1 crifan admin 235B 4 17 11:05 /usr/local/bin/pip -rwxr-xr-x 1 crifan admin 235B 4 17 10:18 /usr/local/bin/pip2 -rwxr-xr-x 1 crifan admin 235B 4 17 10:18 /usr/local/bin/pip2.7 lrwxr-xr-x 1 crifan admin 33B 4 17 10:52 /usr/local/bin/pip3 -> ../Cellar/python/3.6.4_4/bin/pip3 lrwxr-xr-x 1 crifan admin 35B 4 17 10:52 /usr/local/bin/pip3.6 -> ../Cellar/python/3.6.4_4/bin/pip3.6 ➜ robotDemo pip3 --version pip 10.0.0 from /usr/local/lib/python3.6/site-packages/pip (python 3.6) </code>
以用户模式安装pipenv：

【已解决】pipenv安装后警告：The script virtualenv is installed in which is not on PATH
然后再看看能否找到刚安装的程序了，分别看看版本：
<code>➜ robotDemo pipenv --version pipenv, version 11.10.0 ➜ robotDemo pipenv-resolver --version Traceback (most recent call last): File "/Users/crifan/Library/Python/3.6/bin/pipenv-resolver", line 11, in <module> sys.exit(main()) File "/Users/crifan/Library/Python/3.6/lib/python/site-packages/pipenv/resolver.py", line 71, in main sources=project.sources, File "/Users/crifan/Library/Python/3.6/lib/python/site-packages/pipenv/project.py", line 620, in sources if 'source' in self.parsed_pipfile: File "/Users/crifan/Library/Python/3.6/lib/python/site-packages/pipenv/project.py", line 373, in parsed_pipfile with open(self.pipfile_location) as f: TypeError: expected str, bytes or os.PathLike object, not NoneType ➜ robotDemo pipenv-resolver --help Traceback (most recent call last): File "/Users/crifan/Library/Python/3.6/bin/pipenv-resolver", line 11, in <module> sys.exit(main()) File "/Users/crifan/Library/Python/3.6/lib/python/site-packages/pipenv/resolver.py", line 71, in main sources=project.sources, File "/Users/crifan/Library/Python/3.6/lib/python/site-packages/pipenv/project.py", line 620, in sources if 'source' in self.parsed_pipfile: File "/Users/crifan/Library/Python/3.6/lib/python/site-packages/pipenv/project.py", line 373, in parsed_pipfile with open(self.pipfile_location) as f: TypeError: expected str, bytes or os.PathLike object, not NoneType ➜ robotDemo pewtwo --version It seems that you're running pew for the first time do you want to modify /Users/crifan/.zshrc to source completions and update your prompt?

结果是：
pewtwo
pipenv-resolver
virtualenv-clone
都是没有版本的：
而：
pipenv： 11.10.0
virtualenv：15.2.0

继续去操作

彩色输出很好看：

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：
<code>➜ robotDemo ll -lha

</code>看看此时的PATH：
<code>➜ robotDemo echo $PATH /Users/crifan/.local/share/virtualenvs/robotDemo-HXjMJQEQ/bin:/Users/crifan/Library/Python/3.6/bin:/Users/crifan/.nvm/versions/node/v5.4.1/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin </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。
后续，就是普通的，安装/下载模块了：
后面应该是
pipenv install flask
之类的了。
看看当前环境再退出：
<code>➜ robotDemo pipenv --where /Users/crifan/dev/dev_root/company/naturling/projects/robotDemo ➜ robotDemo pipenv --venv /Users/crifan/.local/share/virtualenvs/robotDemo-HXjMJQEQ ➜ robotDemo pipenv --py /Users/crifan/.local/share/virtualenvs/robotDemo-HXjMJQEQ/bin/python ➜ robotDemo pipenv --envs The following environment variables can be set, to do various things: - PIPENV_SHELL_FANCY - PIPENV_PYTHON - PIPENV_VENV_IN_PROJECT - PIPENV_TEST_INDEX - PIPENV_COLORBLIND - PIPENV_NOSPIN - PIPENV_MAX_ROUNDS - PIPENV_PIPFILE - PIPENV_DEFAULT_PYTHON_VERSION - PIPENV_DONT_LOAD_ENV - PIPENV_YES - PIPENV_MAX_SUBPROCESS - PIPENV_MAX_DEPTH - PIPENV_NO_INHERIT - PIPENV_VIRTUALENV - PIPENV_USE_SYSTEM - PIPENV_USE_HASHES - PIPENV_SKIP_VALIDATION - PIPENV_DOTENV_LOCATION - PIPENV_HIDE_EMOJIS - PIPENV_TIMEOUT - PIPENV_INSTALL_TIMEOUT - PIPENV_DONT_USE_PYENV - PIPENV_SHELL - PIPENV_CACHE_DIR You can learn more at: http://docs.pipenv.org/advanced/#configuration-with-environment-variables ➜ robotDemo pipenv graph ➜ robotDemo exit ➜ robotDemo which python /usr/bin/python </code>
【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" ] && .

【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。
