如何使用pip
到get-pip.py
设置/usr/local/bin/
的安装路径?我无法在setup guide或命令行选项中找到任何提及。
澄清我并不是指安装pip包的路径,而是安装pip本身的路径(它应该在/usr/local/bin/pip
中)。
修改
我同意很多评论/答案,一般来说,virtualenv会更好。然而,它对我来说根本不是最好的,因为它太具有破坏性;我们的许多用户脚本依赖于python2.7神奇可用;这也不方便也应该改变,但是我们之前一直在使用python,因为在virtualenv之前就是这样。

Pip本身是一个Python包,实际的pip命令只运行一个小的Python脚本,然后导入并运行pip包。
您可以编辑locations.py来更改安装目录,但是,如上所述,我高度建议您不要这样做。
Pip Command
Pip接受一个标志,' - install-option =" - install-scripts"',可用于更改安装目录:
pip install somepackage --install-option="--install-scripts=/usr/local/bin"
来源方法
在pip / locations.py的第124行,我们看到以下内容:
site_packages = sysconfig.get_python_lib()
user_site = site.USER_SITE
您可以在技术上编辑这些以更改默认安装路径,但是,使用虚拟环境将是非常可取的。然后用它来查找egglink路径,然后找到dist路径(下面的代码来自pip/__init__.py
)。
def egg_link_path(dist):
"""
Return the path for the .egg-link file if it exists, otherwise, None.
There's 3 scenarios:
1) not in a virtualenv
try to find in site.USER_SITE, then site_packages
2) in a no-global virtualenv
try to find in site_packages
3) in a yes-global virtualenv
try to find in site_packages, then site.USER_SITE
(don't look in global location)
For #1 and #3, there could be odd cases, where there's an egg-link in 2
locations.
This method will just return the first one found.
"""
sites = []
if running_under_virtualenv():
if virtualenv_no_global():
sites.append(site_packages)
else:
sites.append(site_packages)
if user_site:
sites.append(user_site)
else:
if user_site:
sites.append(user_site)
sites.append(site_packages)
for site in sites:
egglink = os.path.join(site, dist.project_name) + '.egg-link'
if os.path.isfile(egglink):
return egglink
def dist_location(dist):
"""
Get the site-packages location of this distribution. Generally
this is dist.location, except in the case of develop-installed
packages, where dist.location is the source code location, and we
want to know where the egg-link file is.
"""
egg_link = egg_link_path(dist)
if egg_link:
return egg_link
return dist.location
然而,再次使用virtualenv更易于追踪,任何Pip更新都会覆盖这些更改,与您自己的virtualenv不同。

我发现这样做最简单的解决方法是:
easy_install
;这将按预期进入/usr/local/bin/
;执行此操作的步骤列于here;我个人最终运行wget https://bootstrap.pypa.io/ez_setup.py -O - | python
/usr/local/bin/easy_install pip
安装点子;这将使pip
进入/usr/local/bin
