pip install 找不到包 - 从 PyPi 中消失了

Question

我正在编写一个 bash 脚本来将新安装的 Ubuntu VM 设置为在虚拟环境中使用 Django 和 gUnicorn 的开发和测试机器。它使用 apt-get 成功安装了软件包，但是当我对 requirements.txt 文件递归运行 pip 时，它找不到任何软件包。我尝试手动激活虚拟环境并运行 点安装 == 这工作得很好，pip 开始说 Django 已经安装，但其他人都失败了。我试过 --pre 和 --no-index 无济于事。然而，--no-index 确实摆脱了它一直在打印的非常巨大（3000 多行）的 Traceback。

这是脚本：

# VARIABLES
# none for now

# COLORED OUTPUT
function echo_green {
    tput setaf 2
    echo $1
    tput sgr0
}

function echo_yellow {
    tput setaf 3
    echo $1
    tput sgr0
}
function echo_red {
    tput setaf 1
    echo "Important Note: $1"
    tput sgr0
}
function echo_blue {
    tput setaf 4
    echo $1
    tput sgr0
}

sudo easy_install 'distribute==0.6.28'
echo_yellow "If pip tries to install a specific version of something, this can be a mess if it's already installed. Use pip uninstall first. Do not install with anything but pip if possible. Use pip in virtual env. Anything else has potential for mess making and bug hiding."
# TODO: make sure python is v 2.7.5
# Note the lack of sudo. This is related to virtualenv. We're not doing this globally.
 # pip install --upgrade pip
easy_install --upgrade pip
pip install -r ./Services/requirements.txt --pre # --no-index might solve some errors

# mysqlclient-dev

# mysql server?

# then put the dump into it

我得到的错误：

使用 /home/bret/Work/Environment/lib/python2.7/site-packages/pip-1.5.2-py2.7.egg pip 处理依赖关系 完成处理依赖关系 pip 忽略索引：https://pypi.python.org/simple/ 要求 已经满足（使用--upgrade 升级）：Django==1.5.1 in ./Environment/lib/python2.7/site-packages（来自 -r ./Services/requirements.txt（第 1 行））下载/解包 Fabric==1.7.0（来自 -r ./Services/requirements.txt（第 2 行））可以 找不到任何满足 Fabric==1.7.0 要求的下载 （来自 -r ./Services/requirements.txt（第 2 行））清理...否 Fabric==1.7.0 的所有分布（来自 -r ./Services/requirements.txt（第 2 行））为失败存储调试日志 /home/bret/.pip/pip.log

几个线索：

pip install "Django==1.5.1"
pip install "distribute==0.6.28"
cat Services/requirements.txt | sed '/distribute/d' | sed '/distribute/d' > .requirements_tmp.txt
pip install -r .requirements_tmp.txt --use-mirrors --pre  --no-index #might solve some errors
rm .requirements_tmp.txt

这适用于明确给出自己行的包。它使用 sed 将它们从需求的临时副本中删除，然后运行 ​​pip。出于某种原因，使用 -r 导致 pip 找不到任何东西

我已经尝试过标志： --pre --无索引 --使用镜像

我也尝试更新和升级 Ubuntu

确保

• 包确实存在并且没有被删除（PyPi 的第一条规则是永远不要删除包）。见简单索引https://pypi.python.org/simple/

• 没有--no-site-packages，没有与virtualenv版本冲突的系统范围包。

• 包名不存在区分大小写的问题
