我通过下载virtualenv
安装了pip,并创建了一个bootstrap virtualenv,如this answer中所述。
现在我想尝试pipenv
,所以我使用我的bootstrap virtualenv来创建一个新的virtualenv,然后运行pip install pipenv
。现在我可以使用pipenv
,但它发现它已经在virtualenv中运行,并且没有创建新的。
如何让pipenv
创建一个新的virtualenv,这样我就可以为每个项目提供单独的virtualenv?我试过了pipenv install -h
,但没有一个选项看起来很有希望。

current documentation听起来像你可以设置环境变量{
"size": 0,
"aggs": {
"HEATMAP": {
"date_histogram": {
"field": "created",
"interval": "day"
},
"aggs": {
"BEHAVIOUR_CHANGE": {
"terms": {
"field": "labels",
"include": "behavior-change"
}
},
"FIRST_OCCURRENCE": {
"terms": {
"field": "labels",
"include": "first-occurrence"
}
}
}
}
}
}
,以避免重用已经激活的virtualenv:
{
"size": 0,
"aggs": {
"HEATMAP": {
"date_histogram": {
"field": "created",
"interval": "day"
},
"aggs": {
"BEHAVIOUR_CHANGE": {
"filter": {
"regexp": {
"labels": "behavior-change"
}
}
},
"FIRST_OCCURRENCE": {
"filter": {
"regexp": {
"labels": "first-occurrence"
}
}
}
}
}
}
}
我必须承认,我还没试过这个。

如果您在新项目目录中,这些命令会使用pipenv创建一个新的virtualenv:
使用python 2创建一个新的virtualenv:
pipenv --two
使用python 3创建一个新的virtualenv:
pipenv --three
使用任意python版本创建一个新的virtualenv:
pipenv --python 3.6.4

对于这种情况,pipenv似乎变得越来越聪明。这对我有用。首先,我在virtualenv的installation documentation之后安装了一个引导环境,以从源代码本地使用它。这样,我无需接触系统Python,就可以在引导环境中安装pipenv:
test/foo/__init__.py", line 2, in <module>
from test.foo.a import begin
File "/test/foo/a.py", line 17, in <module>
from . import foo
ImportError: cannot import name api
然后我创建了一个新的项目文件夹,并使用pipenv安装了numpy:
$ curl --location --output virtualenv.tar.gz https://github.com/pypa/virtualenv/tarball/16.1.0
$ tar -xzf virtualenv.tar.gz
$ python pypa-virtualenv-4ad2742/src/virtualenv.py vbootstrap
$ rm -r virtualenv.tar.gz pypa-virtualenv-4ad2742/
$ vbootstrap/bin/pip install pipenv
为了易于使用,我创建了一个符号链接:
$ mkdir my_project
$ cd my_project
$ ../vbootstrap/bin/pipenv install numpy

To activate this project's virtualenv, run pipenv shell.
Alternatively, run a command inside the virtualenv with pipenv run.
