Question

我正在按照本教程中的说明尝试$ sudo pip3 install iconservice： https://medium.com/@2infiniti/creating-icon-dapp-from-a-z-part-1-tools-environment-dd56f8dfc905。

我正在运行OS-X。

我收到以下错误消息，我不确定发生了什么。我已经按照其他地方的指示弄乱了cflags，但是没有任何变化。

35 warnings and 4 errors generated.
error: command 'clang' failed with exit status 1

似乎iconservice软件包requires libsecp256k已安装在您的系统上。

Building wheel for secp256k1 (setup.py) ... error
ERROR: ...
ERROR: 0.29.1
Using bundled libsecp256k1
...
Failed to build secp256k1

对于Linux，只需按照Setup on Linux步骤首先安装即可：

$ sudo apt-get install libleveldb1 libleveldb-dev libsecp256k1-dev
$ pip install iconservice

对于Mac OS X，它需要执行更多步骤：

# install leveldb
$ brew install pkg-config automake libtool leveldb

# install libsecp256k (from source)
# based on this (https://github.com/bitcoin-core/secp256k1#build-steps)
$ git clone https://github.com/bitcoin-core/secp256k1.git
$ cd secp256k1/
$ ./autogen.sh
$ ./configure
$ make

# install plyvel
# based on this (https://github.com/wbolster/plyvel/issues/66#issuecomment-460094085)
$ mv /Applications/XCode.app /Applications/Xcode_cp.app
$ leveldb_version=$(ls /usr/local/Cellar/leveldb/ | tail -1)
$ CFLAGS="-mmacosx-version-min=10.7 -stdlib=libc++" \
pip install plyvel \
--no-cache-dir \
--global-option=build_ext \
--global-option="-I/usr/local/Cellar/leveldb/${leveldb_version}/include/" \
--global-option="-L/usr/local/lib"
$ mv /Applications/XCode_cp.app /Applications/Xcode.app
$ pip freeze | grep plyvel
plyvel==1.1.0

# download icon-service source
$ git clone https://github.com/icon-project/icon-service.git

# edit the requirements.txt included with the icon-service source
# to update the plyvel version to match what's already installed
# on your machine (from the previous step)
$ cd icon-service
$ vim requirements.txt
$ cat requirements.txt
    ...
    plyvel==1.1.0  <-- I updated this from 1.0.5
    ...

# build and install iconservice from wheels
$ ./build.sh
$ CFLAGS="-mmacosx-version-min=10.7 -stdlib=libc++" \
pip install dist/iconservice-1.3.0-py3-none-any.whl \
--no-cache-dir \
--global-option=build_ext \
--global-option="-I/usr/local/Cellar/leveldb/${leveldb_version}/include/" \
--global-option="-L/usr/local/lib"

请注意，我从源代码安装了iconservice，因为pip install iconservice仍然失败（我认为该轮子不适用于Mac OS X）。然后，我还从plyvel源文件中的 requirements.txt 文件中更新了iconservice版本，因为从车轮上安装它需要1.0.5版本，但是我已经有了plyvel为1.1.0（我不知道这是否会对软件包的行为产生影响。）。

另一方面，如果您已经在使用虚拟环境，那么您不应该再将sudo与pip install一起使用。使用virtualenv的目的是避免“弄脏”系统软件包，如果您使用sudo，则有悖于virtualenv的目的。
