pip在未安装git时尝试使用git

我有一个项目文件夹,它是一个git存储库(有一个.git文件夹).当我使用该命令时pip freeze,pip尝试使用git.但是,我的系统上没有安装git,因此会导致错误:

(env) PS C:\Users\eclaird\work\myproject> pip freeze
Cannot find command 'git'
Storing complete log in C:\Users\eclaird\pip\pip.log
(env) PS C:\Users\eclaird\work\myproject>

pip.log:

有没有办法在pip中禁用git集成？

(pip 1.4.1,Python 2.7.6)

很不幸的是,不行.没有配置选项来启用/禁用后端.

通过挖掘代码找到的详细信息:

Git模块始终注册:在pip/install .py中,导入git模块.在它结束时,它会自己注册,因此只要在'git.Git'中声明的一个方案与依赖的url匹配,就会被查询.
```
schemes = ('git', 'git+http', 'git+https', 'git+ssh', 'git+git', 'git+file')
```
没有处理异常 Funnily,冻结预计在确定要冻结的依赖URL时可能会发生错误.来自pip.FrozenRequirement的摘录:
```
try:
    req = get_src_requirement(dist, location, find_tags)
except InstallationError:
    logger.warn("Error when trying to get requirement for VCS system %s, falling back to uneditable format" % ex)
```
InstallationError继承自PipError.不幸的是,引发了类型'BadCommand'的例外,它继承自'aptError'.

所以,除了黑客攻击:你无能为力.如果你需要这个,你需要安装git,破解源代码或模拟git可执行文件.如果你选择后者,对于初学者你需要伪造'git config remote.origin.url',它在pip.vcs.git.Git.get_url中被调用(并失败).

希望有所帮助,即使它不是肯定的.;)
