我通常通过pip安装了python包.

对于Google App Engine,我需要将软件包安装到另一个目标目录.

我试过了:

pip install -I flask-restful --target ./lib

但它失败了:

必须提供home或prefix/exec-prefix - 而不是两者

我怎样才能让它发挥作用？

在macOS Sierra中,启用openmp的xgboost安装总是失败.

来自https://xgboost.readthedocs.io/en/latest/build.html,

我试过了:

cp make/config.mk ./config.mk; make -j4

随着,

export CC=/usr/local/Cellar/llvm/4.0.0_1/bin/clang
export CXX=/usr/local/Cellar/llvm/4.0.0_1/bin/clang++
export CXX1X=/usr/local/Cellar/llvm/4.0.0_1/bin/clang++

它失败了,

clang-4.0clang-4.0: : warning: argument unused during compilation: '-pthread' [-Wunused-command-line-argument]warning:
argument unused during compilation: '-pthread' [-Wunused-command-line-argument]
ld: library not found for -lomp
ld: library not found for -lomp
clang-4.0: error: linker command failed with exit code 1 (use -v to see invocation)

llvm支持openmp,但它失败了 ld: library not found for -lomp

相关问题 在Mac上安装xgboost - ld:找不到库

但是,clang-omp去了boneyard,并停止了llvm的OpenMP支持.

我已经钻了,(有-v选项)
