Question

我在microSD卡上保留了一个项目，因为我希望能够在设备之间传输它。因此，我将所有库都放在microSD上。

我想安装microSD中的所有库，而不是他们的存储库，所以我在每个设备之间都有相同的版本。因此，我希望程序在我第一次在计算机上运行时自动安装这些库。

我在这里有一大堆代码可以解决这个问题：

import os
import sys

#Get the project base directory (drive located on)
def get_project_base_directory():
    global basedir
    cwd = os.getcwd()
    basedir = "/".join(cwd.split("\\")[:len(cwd.split("\\"))-1])
    print basedir


#Install libraries if they don't exist on this machine.
def install_libs():
    libs_list = ("fbchat", "gTTS", "PyAudio", "pygooglevoice", "espeak", "pywapi", "speech_recognition") #names of libs
    libs_file_list = ("/Libraries/Installed/fbchat-1.0.19/setup.py", "/Libraries/Installed/gTTS-1.2.2/setup.py", "/Libraries/Installed/PyAudio-0.2.11/setup.py", "/Libraries/Installed/pygooglevoice-master/setup.py", "/Libraries/Installed/python-espeak-0.5/setup.py", "/Libraries/Installed/pywapi-0.3.8/setup.py", "/Libraries/Installed/speech_recognition-master/setup.py") #lib location, without drive name
    for lib in libs_list:
        var = lib in sys.modules
        if var == False:
            print "Installing:", lib
            lib_file = basedir + libs_file_list[libs_list.index(lib)] #Temporarily adds drive name during install process
            try:
                os.system("python " + lib_file + " install")
            except:
                print lib, "failed installation. Try manual install."

所有标记为未在此计算机上安装（这是真的）。但是，它们在尝试安装时都会返回错误（“处理”除外）。

这是他们的回报：

但README.rst确实存在（我检查过，所有其他“不存在的”文件也是如此）。为什么会发生这种情况？我怎么能解决这个问题，除了进入并手动安装每个lib（如果我有10个以上的库，这将是一个痛苦的事。）

我也很好奇如何进行版本控制。即，如果此设备上存在旧版本，如何使用我的新版本覆盖它，而不是每次都在我的机器上安装lib？

编辑1：即使我手动执行此操作（通过CMD），我仍然会挂起README.rst不存在...任何想法？

尝试使用python安装python模块
