安装 pip pyicu 出错

Question

我一直在尝试在我的 mac 上安装 musicbrainz 服务器，并且有一个步骤我必须安装 pip pyicu。我不断收到此错误：

Command "python setup.py egg_info" failed with error code 1 in /private/tmp/pip-build-E50o2C/pyicu/

我已经尝试下载 ez_setup.py 并执行 python ez_setup.py。我已经升级了 setuptools 并单独下载了它们。我不确定还有什么可以尝试的。请帮忙！

Answer 1

我在 mac 上尝试安装多语言时遇到了这个问题（多语言需要 pyicu）。以下为我解决了这个问题。

# Install icu
brew install icu4c

# check newest version
ls /usr/local/Cellar/icu4c/

# Edit pyicu installer to work
git clone https://github.com/ovalhub/pyicu.git

# edit setup.py not to query for the version, i.e. change
# ICU_VERSION = subprocess.check_output(('icu-config', '--version')).strip()
# to whatever your version is, e.g.
# ICU_VERSION = '57.1'

# Install pyicu
env LDFLAGS=-L/usr/local/opt/icu4c/lib CPPFLAGS=-I/usr/local/opt/icu4c/include DYLD_LIBRARY_PATH=-L/usr/local/opt/icu4c/lib python setup.py build
env LDFLAGS=-L/usr/local/opt/icu4c/lib CPPFLAGS=-I/usr/local/opt/icu4c/include DYLD_LIBRARY_PATH=-L/usr/local/opt/icu4c/lib sudo python setup.py install

# Change DYLD_LIBRARY_PATH (not sure if req'd)
DYLD_LIBRARY_PATH=/usr/local/Cellar/icu4c/{version, e.g. 57.1}/:$DYLD_LIBRARY_PATH
echo $DYLD_LIBRARY_PATH

# Icu works now from python, and you can proceed with polyglot
$ python
>>> import icu
$ pip install polyglot
$ python
>>> import polyglot

我在 ubuntu 14.04 和 16.04 遇到过这个问题。要解决此问题，请安装 libicu-dev，然后再次尝试安装。我做到了

$sudo apt install libicu-dev
$pip install pyicu

Answer 3

以下解决方案仅适用于 MAC OSX-

尝试使用 brew 安装 pyICU：

brew install icu4c

如果它说它已经安装并且只需要链接，那么试试这个：

brew link icu4c

这会在“/usr/local/Cellar/icu4c/...”中创建相对符号链接

Answer 4

以下解决方案在 OSX 上对我有用：

# Install ucu4c via Brew
brew install icu4c

# Create relative symlinks for icu4c
brew link --force icu4c

# Install pyicu via pip
# Make sure ICU_VERSION matches the one you just installed
sudo ICU_VERSION=60.2 pip install pyicu

Answer 5

让我让它工作：

1) 用 brew 安装 icu4c:

brew install icu4c
brew link icu4c --force

2) 检查版本：

ls /usr/local/Cellar/icu4c/

它提示如下： 64.2

3) 执行以下命令并替换上一步的正确版本（第一行只有整数部分，第二和第三行有小数部分）：

export ICU_VERSION=64
export PYICU_INCLUDES=/usr/local/Cellar/icu4c/64.2/include
export PYICU_LFLAGS=-L/usr/local/Cellar/icu4c/64.2/lib

4) 最后为 pyicu 安装 python 包:

pip install pyicu --upgrade

如果你在上面失败了（在 OS X 10.15 上已经发生在我身上）你可能需要：

brew install pkg-config

export PYICU_CFLAGS=-std=c++11:-DPYICU_VER='"2.3.1"'

Answer 6

在 macOS 10.14.2 上，只需将包含 icu-config 的目录添加到 PATH 就可以解决问题：

brew install icu4c
export PATH="/usr/local/opt/icu4c/bin:$PATH"
pip install pyicu

其实这是brew info icu4c建议的：

==> Caveats
icu4c is keg-only, which means it was not symlinked into /usr/local,
because macOS provides libicucore.dylib (but nothing else).

If you need to have icu4c first in your PATH run:
  echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> ~/.zshrc
  echo 'export PATH="/usr/local/opt/icu4c/sbin:$PATH"' >> ~/.zshrc

For compilers to find icu4c you may need to set:
  export LDFLAGS="-L/usr/local/opt/icu4c/lib"
  export CPPFLAGS="-I/usr/local/opt/icu4c/include"

For pkg-config to find icu4c you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/icu4c/lib/pkgconfig"

Answer 7

似乎为 brew 打包的当前版本 icu4c 没有正确 link icu-config 文件。

运行 brew link icu4c --force 为您提供解决此问题的必要信息，但无法自动 link。

$ brew link --force icu4c
Warning: Refusing to link macOS-provided software: icu4c
If you need to have icu4c first in your PATH run:
  echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> ~/.bash_profile
  echo 'export PATH="/usr/local/opt/icu4c/sbin:$PATH"' >> ~/.bash_profile

For compilers to find icu4c you may need to set:
  export LDFLAGS="-L/usr/local/opt/icu4c/lib"
  export CPPFLAGS="-I/usr/local/opt/icu4c/include"

For pkg-config to find icu4c you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/icu4c/lib/pkgconfig"

在安装 icu4c 到 brew 之后，您需要运行以下内容才能让 icu-config 进入您的路径（假设您运行ning bash 作为你的 shell):

echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> ~/.bash_profile
echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> ~/.bash_profile
source ~/.bash_profile

之后，您应该可以安装 pyicu 而无需任何额外的环境变量：

$ pip install --no-cache-dir pyicu
Collecting pyicu

    100% |████████████████████████████████| 215kB 4.9MB/s 
Installing collected packages: pyicu
  Running setup.py install for pyicu ... done
Successfully installed pyicu-2.2

总而言之，这是我运行完成这项工作的完整命令列表：

brew install icu4c
brew link icu4c --force
echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> ~/.bash_profile
echo 'export PATH="/usr/local/opt/icu4c/bin:$PATH"' >> ~/.bash_profile
source ~/.bash_profile
pip install --no-cache-dir pyicu

（顺便说一句，我遇到的许多解决方案都没有将 --no-cache-dir 选项与 pip install 一起使用。我认为其中一些可能已经缓存了 pyicu 的构建版本.我做了一段时间，掩盖了这个问题。直到我尝试了这个选项，我才能够重现并适当地修复。）

我试图在 RHEL 中安装，但我是从 tar.gz 文件安装的。以下是命令：

    /usr/local/bin/pip3 install -U setuptools
    /usr/local/bin/pip3 install -U wheel
    wget http://download.icu-project.org/files/icu4c/50.1.2/icu4c-50_1_2-src.tgz
    tar -zxvf icu4c-50_1_2-src.tgz
    cd icu
    cd source
    sudo ./configure --prefix=/usr
    sudo make
    sudo make install
    icu-config --version
    /usr/local/bin/pip3 install PyICU==2.0.6

Answer 9

这失败了，因为 icu4c 是一个仅限小桶的公式，您可以在 brew info icu4c 的注意事项部分看到。

一些其他答案建议使用 brew link icu4c 但这可能 导致其他问题 因为 macOS 已经提供 libicucore.dylib.

pip install pyicu 失败，因为

将尝试运行 icu-config 命令，因此 icu-config 必须在 PATH
将尝试运行 pkgconfig ... icu-i18n 因此 icu4c 的 .pc 文件必须在 PKG_CONFIG_PATH

对于 macOS，如果您不想 brew link icu4c 并且只想让 icu4c 可用于您的 pip install 命令，那么您可以改为这样做：

brew install pkg-config icu4c

# brew info icu4c 
export PATH="/usr/local/opt/icu4c/bin:$PATH"
export PATH="/usr/local/opt/icu4c/sbin:$PATH"
export PKG_CONFIG_PATH="/usr/local/opt/icu4c/lib/pkgconfig"

icu-config --version # 68.2
pkg-config --modversion icu-i18n # 68.2

pip install pyicu==2.6.0 # works because icu-config in PATH and pkgconfig can find icu4c
