[英]“unknown type name 'decltype'”: Installing pyicu on mac failed, with gcc error
[英]Error installing pip pyicu
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:

我试过下载 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!
我在 ubuntu 14.04 和 16.04 上遇到过这个问题。 要解决此问题,请安装 libicu-dev,然后再次尝试安装。 我做了
$sudo apt install libicu-dev
$pip install pyicu
尝试安装多语言时,我在我的 mac 上遇到了这个问题(多语言需要 pyicu)。 以下为我解决了这个问题。
# Install icu
brew install icu4c
# check newest version
ls /usr/local/Cellar/icu4c/
# Edit pyicu installer to work
git clone https://github.com/ovalhub/pyicu.git
# edit setup.py not to query for the version, i.e. change
# ICU_VERSION = subprocess.check_output(('icu-config', '--version')).strip()
# to whatever your version is, e.g.
# ICU_VERSION = '57.1'
# Install pyicu
env LDFLAGS=-L/usr/local/opt/icu4c/lib CPPFLAGS=-I/usr/local/opt/icu4c/include DYLD_LIBRARY_PATH=-L/usr/local/opt/icu4c/lib python setup.py build
env LDFLAGS=-L/usr/local/opt/icu4c/lib CPPFLAGS=-I/usr/local/opt/icu4c/include DYLD_LIBRARY_PATH=-L/usr/local/opt/icu4c/lib sudo python setup.py install
# Change DYLD_LIBRARY_PATH (not sure if req'd)
DYLD_LIBRARY_PATH=/usr/local/Cellar/icu4c/{version, e.g. 57.1}/:$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
让我得到它的工作:
1)用brew安装icu4c
:
brew install icu4c
brew link icu4c --force
2)检查版本:
ls /usr/local/Cellar/icu4c/
它提示类似: 64.2
3)执行波纹管命令,并替换上一步中的正确版本(第一行只有整数部分,第二行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
如果您在上面失败(在 OS X 10.15
上已经发生在我身上),您可能需要:
brew install pkg-config
export PYICU_CFLAGS=-std=c++11:-DPYICU_VER='"2.3.1"'
在 macOS 10.14.2 上,只需将包含icu-config
的目录添加到PATH
就对我有用:
brew install icu4c
export PATH="/usr/local/opt/icu4c/bin:$PATH"
pip install pyicu
事实上,这是brew info icu4c
建议的:
==> Caveats
icu4c is keg-only, which means it was not symlinked into /usr/local,
because macOS provides libicucore.dylib (but nothing else).
If you need to have icu4c first in your PATH run:
echo 'export PATH="/usr/local/opt/icu4c/bin:$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"
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
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
似乎为brew
打包的当前版本的icu4c
没有正确链接icu-config
文件。
运行brew link icu4c --force
为您提供解决此问题的必要信息,但无法自动链接它。
$ 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"
在通过brew
安装icu4c
后,您需要运行以下icu4c
以将icu-config
放入您的路径(假设您正在运行 bash 作为您的 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,您应该能够在没有任何额外环境变量的情况下安装pyicu
:
$ pip install --no-cache-dir pyicu

总而言之,这是我为完成这项工作而运行的完整命令列表:
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
( pyicu
,我遇到的许多解决方案都没有在pip install
使用--no-cache-dir
选项。我认为其中一些可能已经缓存了pyicu
构建版本。我做了一段时间,这掩盖了问题。直到我尝试了这个选项,我才能够正确地重现和修复。)
我试图在 RHEL 中安装,我从 tar.gz 文件安装。 下面是命令:
/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
这失败了,因为icu4c
是一个仅限桶的公式,您可以在brew info icu4c
的警告部分brew info icu4c
。
其他一些答案建议使用brew link icu4c
但这可能会导致其他问题,因为 macOS 已经提供libicucore.dylib
。
pip install pyicu
失败,因为
icu-config
命令,因此icu-config
必须在 PATH 中pkgconfig ... icu-i18n
所以.pc
文件必须在PKG_CONFIG_PATH
对于 macOS,如果您不想brew link icu4c
并且只想使 icu4c 可用于您的pip install
命令,那么您可以这样做:
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
